Physicality

American football is a collision sport. To stop the offense from advancing the ball, the defense must tackle the player with the ball by knocking or pulling him down. As such, defensive players must use some form of physical contact to bring the ball-carrier to the ground, within certain rules and guidelines. Tacklers cannot kick or punch the runner. They also cannot grab the face mask of the runner's helmet or lead into a tackle with their own helmet. Despite these and other rules regarding unnecessary roughness, most other forms of tackling are legal. Blockers and defenders trying to evade them also have wide leeway in trying to force their opponents out of the way. Quarterbacks are regularly hit by defenders coming on full speed from outside the quarterback's field of vision. This is commonly known as a blindside.

To compensate for this, players must wear special protective equipment, such as a padded plastic helmet, shoulder pads, hip pads and knee pads. These protective pads were introduced decades ago and have improved ever since to help minimize lasting injury to players. An unintended consequence of all the safety equipment has resulted in increasing levels of violence in the game. Players may now hurl themselves at one another at high speeds without a significant chance of injury. The injuries that do result tend to be severe and often season or career-ending and sometimes fatal. In previous years with less padding, tackling more closely resembled tackles in Rugby football. Better helmets have allowed players to use their helmets as weapons. This form of tackling is particularly unwise, because of the great potential for brain or spinal injury. All this has caused the various leagues, especially the NFL, to implement a complicated series of penalties for various types of contact. Most recently, virtually any contact with the helmet of a defensive player on the quarterback, or any contact to the quarterback's head, is now a foul.

Despite protective equipment and rule changes to emphasize safety, injuries remain very common in football. It is increasingly rare, for example, for NFL quarterbacks or running backs (who take the most direct hits) to make it through an entire season without missing some time to injury. Additionally, 28 football players, mostly high schoolers, died from direct football injuries in the years 2000-05 and an additional 68 died indirectly from dehydration or other examples of "non-physical" dangers, according to the National Center for Catastrophic Sport Injury Research.^[11] Concussions are common, with about 41,000 suffered every year among high school players according to the Brain Injury Association of Arizona. In 1981, former U.S. President Ronald Reagan, who played football in high school, commented on the contact of the sport: "[Football] is the last thing left in civilization where men can literally fling themselves bodily at one another in combat and not be at war."

Extra and optional equipment such as neck rolls, spider pads, rib protectors (referred to as "flak jackets"), and elbow pads help against injury as well, though they do not tend to be used by the majority of players due to their lack of requirement.

The danger of football and the equipment required to reduce it make regulation football impractical for casual play. Flag football and touch football are less violent variants of the game popular among recreational players.

Basic strategy

Because the game stops after every down, giving teams a chance to call a new play, strategy plays a major role in football. Each team has a playbook of dozens to hundreds of plays. Ideally, each play is a scripted, strategically sound team-coordinated endeavor. Some plays are very safe; they are likely to get only a few yards. Other plays have the potential for long gains but at a greater risk of a loss of yardage or a turnover.

Generally speaking, rushing plays are less risky than passing plays. However, there are relatively safe passing plays and risky running plays. To deceive the other team, some passing plays are designed to resemble running plays and vice versa. These are referred to as play-action passes and draws. There are many trick or gadget plays, such as when a team lines up as if it intends to punt and then tries to run or pass for a first down. Such high-risk plays are a great thrill to the fans when they work. However, they can spell disaster if the opposing team realizes the deception and acts accordingly.

The defense also plans plays in response to expectations of what the offense will do. For example, a "blitz" (using linebackers or defensive backs to charge the quarterback) is often attempted when the team on defense expects a pass. A blitz makes downfield passing more difficult but exposes the defense to big gains if the offensive line stems the rush.

Many hours of preparation and strategizing, including film review by both players and coaches, go into the days between football games. This, along with the demanding physicality of football (see below), is why teams typically play at most one game per week.

Special teams

"Special teams" redirects here. For the ice hockey definition of "special teams," see powerplay and short handed.

Special teams are units that are on the field during kickoffs, free kicks, punts, field goal and extra point attempts. Most special teams players are second- and third-string players from other positions.

Special teams are unique in that they can serve as offensive or defensive units and that they are only seen sporadically throughout a game.

Special teams include a kickoff team, a kick return team, a punting team, a punt blocking/return team, a field goal team and a field goal block team.

There are also specialized players on these teams, including:

• Kicker (K) — Handles kickoffs and field goal attempts, and in some leagues, punts as well.
• Holder (H) — Usually positioned 7-8 yards from the line of scrimmage, he holds the ball for the placekicker to kick. The holder is often a backup quarterback or a punter.
• Long snapper (LS) — A specialized center who snaps the ball directly to the holder or punter. The long snapper is often an offensive linemen or backup Tight End; rarely a center.
• Kick returner (KR) — Returns kickoffs, generally is also a wide receiver or cornerback.
• Punter (P) — Kicks punts. In leagues other than the NFL, the kicker often doubles as the punter.
• Upback — A blocking back that lines up approximately 1-3 yards behind the line of scrimmage in punting and kneel situations. His primary job is to act as a second line of defense for the punter. Upbacks can receive a direct snap in fake punt situations.
• Punt returner (PR) — Returns punts. Often the same player as the kick returner, although not necessarily so.
• Gunner — A player on kickoffs and punts who specializes in running down the field very quickly in an attempt to tackle the kick returner or the punt returner.
• Wedge Buster — A player whose goal is to sprint down the middle of the field on kickoffs. While ideally, their goal is to reach the kick returner, their immediate goal is to disrupt the wall of blockers (the wedge) on kickoffs, preventing the returner from having a lane in which to get a substantial return. Being a wedge buster is a very dangerous position since he may often be running at full speed when coming into contact with a blocker.
• Hands Team — Used only during onside kicks, the members of a hands team are responsible for preventing the kicking team from recovering a kick, usually by recovering the ball themselves.

Because these aspects of the game can be so different from general offensive and defensive play, a specific group of players is drilled in executing them. Though fewer points are scored on special teams than on offense, special teams play determines where the offense will begin each drive, and thus it has a dramatic impact on how easy or difficult it is for the offense to score.

Defense

The defensive team or defense is the team that begins a play from scrimmage not in possession of the ball. The object of the defensive team is to prevent the other team from scoring. The sign that the defensive goal has been accomplished is a fourth down, which usually involves punting the ball.

Unlike the offensive team, there are no formally defined defensive positions. A defensive player may line up anywhere on his side of the line of scrimmage and perform any legal action. However, most sets used in football include a line composed of defensive ends and defensive tackles and (behind the line) linebackers, cornerbacks, and safeties.

Defensive ends and tackles are collectively called defensive line, while the cornerbacks and safeties are collectively called the secondary, or defensive backs.

• Defensive end (DE) — The two defensive ends play on opposite outside edges of the defensive line. Their function is to attack the passer or stop offensive runs to the outer edges of the line of scrimmage (most often referred to as "containment"). The faster of the two is usually placed on the right side of the defensive line (quarterback's left) because that is a right-handed quarterback's blind side.

• Defensive tackle (DT) — Sometimes called a defensive guard, defensive tackles are side-by-side linemen who are between the defensive ends. Their function is to rush the passer (if they can get past the offensive linemen blocking them), and stop running plays directed at the middle of the line of scrimmage. A defensive tackle that lines up directly across from the ball (and therefore, is almost nose-to-nose with the offense's center) is often called a nose tackle or nose guard. The nose tackle is most common in the 3-4 defense and the quarter defense. Most defensive sets have from one to two defensive tackles. Sometimes, but not often, a team will employ three defensive tackles.

• Linebacker (LB) — Linebackers play behind the defensive line and perform various duties depending on the situation, including rushing the passer, covering receivers, and defending against the run. Most defensive sets have between two and three linebackers. Linebackers are usually divided into three types: strongside (left or right outside linebacker: LOLB or ROLB); middle (MLB); and weakside (LOLB or ROLB). The strongside linebacker usually lines up across from the offense's tight end; he is usually the strongest LB because he must be able to shed lead blockers quickly enough to tackle the running back. The middle linebacker must correctly identify the offense's formations and what adjustments the entire defense must make. Because of this, the middle linebacker is nicknamed the "quarterback of the defense". The weakside linebacker is usually the most athletic or fastest linebacker because he usually must defend an open field.

• Cornerback (CB) — Typically two players that primarily cover the wide receivers. Cornerbacks attempt to prevent successful quarterback passes by either swatting the airborne ball away from the receiver or by catching the pass themselves. In rushing situations, their job is to contain the rusher.

• Safety (FS or SS) — The safeties are the last line of defense (farthest from the line of scrimmage) and usually help the corners with deep-pass coverage. The strong safety (SS) is usually the larger and stronger of the two, providing extra protection against run plays by standing somewhere between the free safety and the line of scrimmage. The free safety (FS) is usually the smaller and faster of the two, providing variable and extra pass coverage. Traditionally, teams have looked for safeties with reputations as hard hitters. More recently, however, teams have been looking for hybrid safeties who can do both jobs, as in a cover 2 defense, when the strong safety has a greater role to play in coverage. Safeties are also used in a variety of blitzes.

Defensive back — It is not a specific position, however, it is any position besides the line, including cornerbacks, safeties, etc., that is behind the line of scrimmage.

• Nickelback and Dimeback — In certain formations one extra (a fifth) defensive back (called a nickel defense), two extra (a sixth) DB (called a Dime package), or even three extra (a seventh) DB called a Quarter may be used to augment the backfield or defensive line. Nickelbacks, dimebacks, and Defensive Quarterbacks are usually used to defend pass plays with extra receivers, but they can also be used to rush quarterbacks or running backs more quickly than linemen or most linebackers can. A starting cornerback who is good at blitzing and tackling will sometimes be referred to as a nickelback to distinguish them from cornerbacks.

Offense

The offensive team or offense in football is the team that begins a play from scrimmage in possession of the ball. A play usually begins when the quarterback takes a snap from the center and then either hands off to a back, passes to a receiver or a back, runs the ball himself, spikes the ball, or takes a knee.

The purpose of spiking the ball is to stop the play clock if the offense is running out of time. The purpose of taking a knee is to waste time. If a player runs the ball and stays in bounds, or if a player receives a pass and stays in bounds (this has the same effect as taking a knee), then the clock keeps ticking. But if a player runs out of bounds, or there is an incomplete pass (this also counts as spiking the ball), then the clock stops.

Usually the sign that their goal is accomplished for the offensive team is the touchdown. However, the offensive team can also help the team score by getting good field position for an attempt at a field goal.

The offensive unit in football consists of a quarterback, linemen, backs, tight ends and receivers. The function of most of the linemen is to block. The offensive line consists of a center, two guards, two tackles and one or two tight ends. Backs include running backs (or tailbacks) who frequently carry the ball, and a fullback, who usually blocks, and occasionally carries the ball or receives a pass. The primary function of the wide receivers is to catch passes.

The ultimate makeup of the offense and how it operates is governed by the head coach or offensive coordinator's offensive philosophy.

• Center (C)—the center performs the normal blocking functions of all linemen and is the player who puts the ball in play by means of the snap.
• Offensive guard (OG)—the two guards are the offensive linemen directly on either side of the center and inside the tackles. Like all interior linemen, their function is to block on both running and passing plays. On some plays, rather than blocking straight ahead, a guard will "pull" - moving around behind the other offensive linemen upon the start of the play - in order to block a player on either side of the center, in an inside running play called a "trap" or an outside running play called a "sweep".
• Offensive tackle (OT)—the offensive tackles play on both of the guards outside. Their role is primarily to block on both running and passing plays. The area from one tackle to the other is an area of "close line play" in which some blocks from behind, which are prohibited elsewhere on the field, are allowed. For a right-handed quarterback, the left tackle is charged with protecting the blindside, and is often faster than the other offensive linemen to stop 'speed rushers' at the Defensive End position. Like a guard, the tackle may have to "pull", on a running play, when there is a tight end on his side.

The description above of the guard and tackle positions apply only to a line that is balanced (has equal numbers of players on both sides of the player who is to snap the ball). In an unbalanced line, there may be players designated "guard" or "tackle" next to each other.

Offensive linemen can not catch the ball but may run the ball if they want. In most circumstances, however, they do not. Except for the snap by the offensive center as each play from scrimmage starts, ordinarily the only way an offensive lineman can get the ball during a play is by picking up a fumble. On rare occasions offensive linemen legally catch passes; they can do so either by reporting as an eligible receiver to the referee prior to the snap or by catching a pass which has first been deflected or otherwise touched by an eligible receiver or a defensive player. Any other touching of the ball by an offensive lineman will result in a penalty.

• Tight end (TE) — Tight ends play on either side of, and roughly next to, the tackles. They are a mix between a blocker and a pass receiver. If an end moves away from the tackle, he is called a split end. Modern formations typically have one tight end and one split end. Many modern formations also forego tight ends and replace them with wide receivers. Sometimes a formation is referred to as having "three tight ends." This means in reality that an additional blocker (a wingback or an eighth lineman) has been substituted for a wide receiver. This would be done as in short-yardage situations where receivers are not needed.

• Wide receiver (WR) — The wide receivers are speedy pass-catching specialists. Their main job is to run pass routes and get open for a pass, although they are occasionally called on to block. A wide receiver may line up on the line of scrimmage and be counted as one of the necessary 7 players on the line in a legal formation (a split end), or he may line up at least one step behind the line of scrimmage and be counted as being in the backfield (a flanker if he is on the outside, a slot if he is not). There are generally two types of wide receivers, "speed" and "possession". A speed receiver's primary function is to stretch the field, to be a deep threat, and to pull away an eighth defensive man near the line of scrimmage from moves against the quarterback. A possession receiver is generally the more sure-handed of the two types and is used to keep possession of the ball by making catches that gain first down yardage, but he usually lacks the speed to attack a defensive backfield.

• Fullback (FB) — Positioned behind the middle of the line, a fullback may do some running, some blocking, and some short receiving. A classic fullback is more of a power runner than a running back. Many modern formations do not use a fullback. Most plays utilizing the fullback call for him to block, generally by running up the middle of the line, clearing a path for a running back to run while having the ball to gain yardage.

Penn State Nittany Lions quarterback #14 Anthony Morelli hands the ball off to his tailback #33 Austin Scott in their 2007 season opener.

• Running back (RB) — The modern term for the position formerly called "halfback". The running back carries the ball on most running plays and is also frequently used as a short-yardage receiver. Running backs, along with the wide receivers, are generally the fastest players on the offensive team. Most of them tend not to run straight ahead, preferring to make quick cutbacks to try to find holes in the defense. This, however, is a generalization, since some running backs are more power-oriented. "Fullback" is now regarded as a separate position from running back, with a substantially different role (especially in the NFL).

• Tailback (TB) — A running back that is positioned behind the middle of the line and deepest of all backs.

• H-back — A position that was popularized by Joe Gibbs during his first tenure with the Washington Redskins, the H-back is a hybrid position that combines the skill sets of fullback, tight end, and even wide receiver. An H-back lines up similarly to a slotback—but deeper and not as wide—and frequently serves as a blocker for a more deeply positioned back.

• Wingback — A player positioned just outside the outermost tight end, the wingback is slightly offset from the line of scrimmage which designates the position as wingback rather than tight end. The wingback is typically used in extreme blocking situations or unbalanced offensive formations.

• Slotback — A player positioned just outside the outermost offensive lineman, the slotback is slightly offset from the line of scrimmage which designates the position as a slotback rather than a tight end. The slotback is a typical position in flexbone formations and other Triple Option formations.

• Quarterback (QB) — Typically the quarterback is positioned to take a snap handed between the center's legs. However, recent usage refers imprecisely to a player who is positioned behind the center at any distance, calls signals, is not the usual punter or place kick holder, and usually takes the snap as "quarterback" regardless of exact position, because those functions have typically been performed by quarterbacks. Typical play from formations where the quarterback takes the snap proceeds by the quarterback either handing the ball off to a running back to run, throwing the ball downfield, or running personally.

Teams can vary the number of wide receivers, tight ends and running backs on the field at one time. Football rules limit the flexibility of offensive formations. Seven players must line up on the line of scrimmage, and only the two at the end are eligible to catch passes. Sometimes, offensive lineman can declare eligibility and become "tackle eligible." Jumbo Elliott and Dan Klecko are two tackles who have caught touchdowns while being tackle eligible. Typical formations include:

• One running back, two tight ends and two wide receivers.
• Two running backs, one tight end and two wide receivers.
• One running back, one tight end and three wide receivers.
• One running back, no tight end and four wide receivers.
• No running backs, no tight end and five wide receivers.

A Common Youth and High School Formation is different but effective.

Cambridge University Football Club

The playing of football had always been popular in Cambridge and in 1579 one match played at Chesterton between townspeople and Cambridge University students ended in a violent brawl that led the Vice-Chancellor to issue a decree forbidding them to play "footeball” outside of college grounds. Despite this and other decrees, football continued to be popular in Cambridge, as Dr. G.E. Corrie, Master of Jesus College, observed in 1838, "In walking with Willis we passed by Parker's Piece and there saw some forty Gownsmen playing at football. The novelty and liveliness of the scene were amusing!" . As a result of its role in the formation of the first football rules, Parker's Piece, Cambridge, remains hallowed turf for football fans and historians.

In 1846, H. de Winton and J.C. Thring, who had both attended Shrewsbury School, succeeded in making some old Etonians join them to form a football club at Cambridge University. Only a few matches were ever played, but in 1848 interest in the sport was renewed. The story of how the 1848 rules were formulated was related by Mr H.C. Malden in a letter dated 8 October 1897.

I went up to Trinity College Cambridge. In the following year an attempt was made to get up some football in preference to the hockey that was then in vogue. But the result was dire confusion, as every man played the rules he had been accustomed to at his public school. I remember how the Eton men howled at the Rugby men for handling the ball. So it was agreed that two men should be chosen to represent each of the public schools, and two who were not public school men, for the 'Varsity. G. Salt and myself were chosen for the 'Varsity. I wish I could remember the others. Burn of Rugby, was one; Whymper of Eton, I think, also. We were 14 in all I believe. Harrow and Eton Rugby, Winchester, Shrewsbury were represented. We met in my rooms after Hall, which in those days was at 4.pm.; anticipating a long meeting, I cleared the tables and provided pens, ink and paper. Several asked me on coming in whether an exam was on! Every man brought a copy of his school rules, or knew them by heart, and our progress in framing new rules was slow. On several occasions Salt and I, being unprejudiced, carried or struck out a rule when the voting was equal. We broke up five minutes before midnight. The new rules were printed as the "Cambridge Rules", copies were distributed and pasted up on Parker's Piece, and very satisfactorily they worked, for it is right to add that they were loyally kept, and I never heard of any public school man who gave up playing from not liking the rules. [...] Well Sir, years afterwards someone took these rules, still in force at Cambridge, and with a very few alterations they became the Association Rules. A fair catch, free kick (as still played at Harrow) was struck out. The offside rule was made less stringent. "Hands" was made more so; this has just been wisely altered.

The creators of the Cambridge rules sought to formulate a game that was acceptable to students who had played various codes of public school football. The public school games included a wide range of rules, from the Rugby game (with ball handling and backwards passing) through the Eton game (which favoured dribbling and had a tight offside rule) to the Charterhouse football (that involved dribbling and whose representatives favoured rules permitting forward passing). The Off-side rule adopted by the Cambridge rules stated that:

"If the ball has passed a player and has come from the direction of his own goal, he may not touch it till the other side have kicked it, unless there are more than three of the other side before him. No player is allowed to loiter between the ball and the adversaries' goal(1856, probably earlier)

This rule was subsequent adopted by the Football Association in 1867. This off-side rule, which permitted players to move in front of the ball opened the way to the subsequent development of the Combination Game.

The Cambridge Rules were the first formulated rules of football and the predecessor of modern Association Football. They were very influential in the creation of the modern rules of soccer drawn up in London by Ebenezer Cobb Morley for the Football Association, as shown in the following praise:

'The Cambridge Rules appear to be the most desirable for the Association to adopt'—C. W. Alcock 1863, FA Committee Member and founder of the FA Cup.

'They embrace the true principles of the game, with the greatest simplicity'—E. C. Morley, F.A. Hon. Sec. 1863.

A plaque has been mounted at Parker's Piece, Cambridge to document its unique role in the creation of modern football. It bears the following inscription:

Here on Parker's Piece, in the 1800s, students established a common set of simple football rules emphasising skill above force, which forbade catching the ball and 'hacking'. These 'Cambridge Rules' became the defining influence on the 1863 Football Association rules.

Sheffield Rules

The Sheffield Rules was a code of football devised and played in the English city of Sheffield between 1857 and 1877. They were devised by Nathaniel Creswick and William Prest for use by the newly founded Sheffield Football Club. The rules were subsequently adopted as the official rules of Sheffield Football Association upon its creation in 1867. They spread beyond the city boundaries to other clubs and associations in the north and midlands of England making them one of the most popular forms of football during the 1860s and 70s.

Six years after the creation of the Sheffield Rules the Football Association rules were created. These were influenced by the Sheffield game but ongoing disputes meant that the Sheffield rules continued to be used. During this time many of the elements of the rules were incorporated in to the association game. Regular games were played between Sheffield and London using both sets of rules. This led to an agreement on a single set of laws administered by the Football Association in 1877.

The rules had a major influence on how the modern game of football developed. Among other things they introduced the concept of free kicks for fouls, corners and throw-ins into the laws of the game. The abolition of the fair catch also led to their teams to be the first to head the ball. Games played under the rules are also accredited for the development of heading and the origins of the goalkeeper and forward positions. The first inter-club football match and competitive tournament were both played using Sheffield Rules.

Australian rules

An Australian rules football match at the Richmond Paddock, Melbourne, in 1866. (A wood engraving by Robert Bruce.)

The invention of Australian rules football is usually attributed to Tom Wills, who published a letter in Bell's Life in Victoria & Sporting Chronicle, on July 10, 1858, calling for a "foot-ball club" with a "code of laws" to keep cricketers fit during winter. (Official sources which include Wills' cousin, H.C.A. Harrison, as a founder of the code are now generally believed to be incorrect.)

Wills had been educated in England, at Rugby School and had played cricket for Cambridge University. The extent to which he was influenced by the various British and Irish football games is a matter of controversy, but there were similarities between some of them and his game. Australian football also has some similarities to the Australian Aboriginal game of Marn Grook (see above), which he reportedly witnessed as a child in western Victoria.

On July 31, 1858, Wills and people responding to his letter met and experimented with various forms of football. On August 7, Wills was one of the umpires at a game between Melbourne Grammar School and Scotch College, which took place under modified Rugby School rules.

Melbourne Football Club was founded on May 14, 1859, and is the oldest surviving Australian football club, and on May 17, 1859, at the Parade Hotel, East Melbourne, members of the club drew up the first set of laws for Australian rules football. The drafters included Wills, W.J. Hammersley, J.B. Thompson and Thomas Smith. Their code also had pronounced similarities to the Sheffield rules, most notably in the absence of an offside rule, this could be due to Henry Creswick who emigrated from Sheffield and may have been a relative of Nathaniel Creswick. A free kick was awarded for a mark (clean catch). Running while holding the ball was allowed and although it was not specified in the rules, a rugby ball was used. The club shared many members with the Melbourne Cricket Club, which was based at the Melbourne Cricket Ground, and cricket ovals — which vary in size and are much larger than the fields used in other forms of football — became the standard playing field for Australian rules. The 1859 rules did not include some elements which would soon become important to the game, such as the requirement to bounce the ball while running.

Australian rules is sometimes said to be the first form of football to be codified but, as was the case in all kinds of football at the time, there was no official body supporting the rules, and play varied from one club to another. By 1866, however, several other clubs in the Colony of Victoria had agreed to play an updated version of the Melbourne FC rules, which were later known as "Victorian Rules" and "Australasian Rules". The formal name of the code later became Australian rules football (and, more recently, Australian football). By the end of the 19th century, the code had spread to the other Australian colonies and other parts of the world. However, rugby football would remain more popular in New South Wales and Queensland.

Globalisation of Association football

The need for a single body to oversee Association football had become apparent by the beginning of the 20th century, with the increasing popularity of international fixtures. The English Football Association had chaired many discussions on setting up an international body, but was perceived as making no progress. It fell to associations from seven other European countries: France, Belgium, Denmark, Netherlands, Spain, Sweden, and Switzerland, to form an international association. The Fédération Internationale de Football Association (FIFA) was founded in Paris on May 21, 1904. Its first president was Robert Guérin. The French name and acronym has remained, even outside French-speaking countries.

Reform of American football

Both forms of rugby and American football were noted at the time for serious injuries, as well as the deaths of a significant number of players. By the early 20th century in the USA, this had resulted in national controversy and American football was banned by a number of colleges. Consequently, a series of meetings was held by 19 colleges in 1905–06. This occurred reputedly at the behest of President Theodore Roosevelt. He was considered a fancier of the game, but he threatened to ban it unless the rules were modified to reduce the numbers of deaths and disabilities. The meetings are now considered to be the origin of the National Collegiate Athletic Association.

One proposed change was a widening of the playing field. However, Harvard University had just built a concrete stadium and therefore objected to widening, instead proposing legalisation of the forward pass. The report of the meetings introduced many restrictions on tackling and two more divergences from rugby: the forward pass and the banning of mass formation plays. The changes did not immediately have the desired effect, and 33 American football players were killed during 1908 alone. However, the number of deaths and injuries did gradually decline.

Further divergence of the two rugby codes

Rugby league rules diverged significantly from rugby union in 1906, with the reduction of the team from 15 to 13 players. In 1907, a New Zealand professional rugby team toured Australia and Britain, receiving an enthusiastic response, and professional rugby leagues were launched in Australia the following year. However, the rules of professional games varied from one country to another, and negotiations between various national bodies were required to fix the exact rules for each international match. This situation endured until 1948, when at the instigation of the French league, the Rugby League International Federation (RLIF) was formed at a meeting in Bordeaux.

During the second half of 20th century, the rules changed further. In 1966, rugby league officials borrowed the American football concept of downs: a team could retain possession of the ball for no more than four tackles. The maximum number of tackles was later increased to six (in 1971), and in rugby league this became known as the six tackle rule.

With the advent of full-time professionals in the early 1990s, and the consequent speeding up of the game, the five metre off-side distance between the two teams became 10 metres, and the replacement rule was superseded by various interchange rules, among other changes.

The laws of rugby union also changed significantly during the 20th century. In particular, goals from marks were abolished, kicks directly into touch from outside the 22 metre line were penalised, new laws were put in place to determine who had possession following an inconclusive ruck or maul, and the lifting of players in line-outs was legalised.

In 1995, rugby union became an "open" game, that is one which allowed professional players. Although the original dispute between the two codes has now disappeared — and despite the fact that officials from both forms of rugby football have sometimes mentioned the possibility of re-unification — the rules of both codes and their culture have diverged to such an extent that such an event is unlikely in the foreseeable future.

Football today

Use of the word "football" in English-speaking countries

The word "football", when used in reference to a specific game can mean any one of those described above. Because of this, much friendly controversy has occurred over the term football, primarily because it is used in different ways in different parts of the English-speaking world. Most often, the word "football" is used to refer to the code of football that is considered dominant within a particular region. So, effectively, what the word "football" means usually depends on where one says it.

The name "soccer" (or "soccer football") was originally a slang abbreviation of the word "association" from "association football" and is now the prevailing term in the United States, Canada, Australia and New Zealand where other codes of football are dominant.

Of the 45 national FIFA affiliates in which English is an official or primary language, only three (Canada, Samoa and the United States) actually use "soccer" in their organizations' official names, while the rest use football (although the Samoan Federation actually uses both). However, in some countries, such as Australia and New Zealand, use of the word "football" by soccer bodies is a recent change and has been controversial. The governing body for Rugby Union in New Zealand changed its name from "New Zealand Rugby Football Union" to "New Zealand Rugby Union" in 2006.

Use of the word "football" in non-English-speaking countries

Generally around the world today the word "football" is in widespread use as the name for association football. In Francophone Québec, where Canadian football is more popular, the sport of association football is known as le soccer and the Canadian code as le football.

Split in Rugby football

The International Rugby Football Board (IRFB) was founded in 1886, but rifts were beginning to emerge in the code. Professionalism was beginning to creep into the various codes of football.

In England, by the 1890s, a long-standing Rugby Football Union ban on professional players was causing regional tensions within rugby football, as many players in northern England were working class and could not afford to take time off to train, travel, play and recover from injuries. This was not very different from what had occurred ten years earlier in soccer in Northern England but the authorities reacted very differently in the RFU, attempting to alienate the working class support in Northern England. In 1895, following a dispute about a player being paid broken time payments, which replaced wages lost as a result of playing rugby, representatives of the northern clubs met in Huddersfield to form the Northern Rugby Football Union (NRFU). The new body initially permitted only various types of player wage replacements. However, within two years, NRFU players could be paid, but they were required to have a job outside sport.

The demands of a professional league dictated that rugby had to become a better "spectator" sport. Within a few years the NRFU rules had started to diverge from the RFU, most notably with the abolition of the line-out. This was followed by the replacement of the ruck with the "play-the-ball ruck", which allowed a two-player ruck contest between the tackler at marker and the player tackled. Mauls were stopped once the ball carrier was held, being replaced by a play-the ball-ruck. The separate Lancashire and Yorkshire competitions of the NRFU merged in 1901, forming the Northern Rugby League, the first time the name rugby league was used officially in England.

Over time, the RFU form of rugby, played by clubs which remained members of national federations affiliated to the IRFB, became known as rugby union.

Gaelic football

In the mid-19th century, various traditional football games, referred to collectively as caid, remained popular in Ireland, especially in County Kerry. One observer, Father W. Ferris, described two main forms of caid during this period: the "field game" in which the object was to put the ball through arch-like goals, formed from the boughs of two trees, and; the epic "cross-country game" which took up most of the daylight hours of a Sunday on which it was played, and was won by one team taking the ball across a parish boundary. "Wrestling", "holding" opposing players, and carrying the ball were all allowed.

By the 1870s, Rugby and Association football had started to become popular in Ireland. Trinity College, Dublin was an early stronghold of Rugby (see the Developments in the 1850s section, above). The rules of the English FA were being distributed widely. Traditional forms of caid had begun to give way to a "rough-and-tumble game" which allowed tripping.

There was no serious attempt to unify and codify Irish varieties of football, until the establishment of the Gaelic Athletic Association (GAA) in 1884. The GAA sought to promote traditional Irish sports, such as hurling and to reject imported games like Rugby and Association football. The first Gaelic football rules were drawn up by Maurice Davin and published in the United Ireland magazine on February 7, 1887. Davin's rules showed the influence of games such as hurling and a desire to formalise a distinctly Irish code of football. The prime example of this differentiation was the lack of an offside rule (an attribute which, for many years, was shared only by other Irish games like hurling, and by Australian rules football).

North American football codes

As was the case in Britain, by the early 19th century, North American schools and universities played their own local games, between sides made up of students. Students at Dartmouth College in New Hampshire played a game called Old division football, a variant of the association football codes, as early as the 1820s.

The "Tigers" of Hamilton, Ontario circa 1906. Founded 1869 as the Hamilton Foot Ball Club, they eventually merged with the Hamilton Flying Wildcats to form the Hamilton Tiger-Cats, a team still active in the Canadian Football League

The first game of rugby in Canada is generally said to have taken place in Montreal, in 1865, when British Army officers played local civilians. The game gradually gained a following, and the Montreal Football Club was formed in 1868, the first recorded football club in Canada.

In 1869, the first game played in the United States under rules based on the English FA (soccer) code occurred, between Princeton and Rutgers. This is also often considered to be the first US game of college football, in the sense of a game between colleges (although the eventual form of American football would come from rugby, not soccer).

Modern American football grew out of a match between McGill University of Montreal, and Harvard University in 1874. At the time, Harvard students are reported to have played the Boston Game — a running code — rather than the FA-based kicking games favored by US universities. This made it easy for Harvard to adapt to the rugby-based game played by McGill and the two teams alternated between their respective sets of rules. Within a few years, however, Harvard had both adopted McGill's rugby rules and had persuaded other US university teams to do the same. In 1876, at the Massasoit Convention, it was agreed by these universities to adopt most of the Rugby Football Union rules. However, a touch-down only counted toward the score if neither side kicked a field goal. The convention decided that, in the US game, four touchdowns would be worth one goal; in the event of a tied score, a goal converted from a touchdown would take precedence over four touch-downs.

Princeton, Rutgers and others continued to compete using soccer-based rules for a few years before switching to the rugby-based rules of Harvard and its competitors. US colleges did not generally return to soccer until the early twentieth century.

Rutgers College Football Team, 1882

In 1880, Yale coach Walter Camp, devised a number of major changes to the American game, beginning with the reduction of teams from 15 to 11 players, followed by reduction of the field area by almost half, and; the introduction of the scrimmage, in which a player heeled the ball backwards, to begin a game. These were complemented in 1882 by another of Camp's innovations: a team had to surrender possession if they did not gain five yards after three downs (i.e. successful tackles).

Over the years Canadian football absorbed some developments in American football, but also retained many unique characteristics. One of these was that Canadian football, for many years, did not officially distinguish itself from rugby. For example, the Canadian Rugby Football Union, founded in 1884 was the forerunner of the Canadian Football League, rather than a rugby union body. (The Canadian Rugby Union was not formed until 1965.) American football was also frequently described as "rugby" in the 1880s.

Rugby football

In Britain, by 1870, there were about 75 clubs playing variations of the Rugby school game. There were also "rugby" clubs in Ireland, Australia, Canada and New Zealand. However, there was no generally accepted set of rules for rugby until 1871, when 21 clubs from London came together to form the Rugby Football Union (RFU). (Ironically, Blackheath now lobbied to ban hacking.) The first official RFU rules were adopted in June 1871. These rules allowed passing the ball. They also included the try, where touching the ball over the line allowed an attempt at goal, though drop-goals from marks and general play, and penalty conversions were still the main form of contest.

The Football Association

During the early 1860s, there were increasing attempts in England to unify and reconcile the various public school games. In 1862, J. C. Thring, who had been one of the driving forces behind the original Cambridge Rules, was a master at Uppingham School and he issued his own rules of what he called "The Simplest Game" (these are also known as the Uppingham Rules). In early October 1863 another new revised version of the Cambridge Rules was drawn up by a seven member committee representing former pupils from Harrow, Shrewsbury, Eton, Rugby, Marlborough and Westminster.

At the Freemason's Tavern, Great Queen Street, London on the evening of October 26, 1863, representatives of several football clubs in the London Metropolitan area met for the inaugural meeting of The Football Association (FA). The aim of the Association was to establish a single unifying code and regulate the playing of the game among its members. Following the first meeting, the public schools were invited to join the association. All of them declined, except Charterhouse and Uppingham. In total, six meetings of the FA were held between October and December 1863. After the third meeting, a draft set of rules were published. However, at the beginning of the fourth meeting, attention was drawn to the recently-published Cambridge Rules of 1863. The Cambridge rules differed from the draft FA rules in two significant areas; namely running with (carrying) the ball and hacking (kicking opposing players in the shins). The two contentious FA rules were as follows:

IX. A player shall be entitled to run with the ball towards his adversaries' goal if he makes a fair catch, or catches the ball on the first bound; but in case of a fair catch, if he makes his mark he shall not run.

X. If any player shall run with the ball towards his adversaries' goal, any player on the opposite side shall be at liberty to charge, hold, trip or hack him, or to wrest the ball from him, but no player shall be held and hacked at the same time.

At the fifth meeting it was proposed that these two rules be removed. Most of the delegates supported this, but F. W. Campbell, the representative from Blackheath and the first FA treasurer, objected. He said: "hacking is the true football". However, the motion to ban hacking was carried and Blackheath withdrew from the FA. After the final meeting on 8 December, the FA published the "Laws of Football", the first comprehensive set of rules for the game later known as football (later known in some countries as soccer).

The first FA rules still contained elements that are no longer part of association football, but which are still recognisable in other games (most notably Australian football): for instance, a player could make a fair catch and claim a mark, which entitled him to a free kick, and; if a player touched the ball behind the opponents' goal line, his side was entitled to a free kick at goal, from 15 yards in front of the goal line.

Modern balls

Modern balls

Richard Lindon (seen in 1880) is believed to have invented the first footballs with rubber bladders.

In Europe, early footballs were made out of animal bladders, more specifically pig's bladders, which were inflated. Later leather coverings were introduced to allow the ball to keep their shape. However, in 1851, Richard Lindon and William Gilbert, both shoemakers from the town of Rugby (near the school), exhibited both round and oval-shaped balls at the Great Exhibition in London. Richard Lindon's wife is said to have died due to lung disease caused by blowing up pig's bladders. Lindon also won medals for the invention of the "Rubber inflatable Bladder" and the "Brass Hand Pump".

In 1855, the U.S. inventor Charles Goodyear — who had patented vulcanized rubber — exhibited a spherical football, with an exterior of vulcanized rubber panels, at the Paris Exhibition Universelle. The ball was to prove popular in early forms of football in the U.S.A.

Firsts (football)

Clubs

During this period, the Rugby school rules appear to have spread at least as far, perhaps further, than the other schools' codes. For example, two clubs which claim to be the world's first and/or oldest football club, in the sense of a club which is not part of a school or university, are strongholds of rugby football: the Barnes Club, said to have been founded in 1839, and Guy's Hospital Football Club, in 1843. Neither date nor the variety of football played is well-documented, but such claims nevertheless allude to the popularity of rugby before other modern codes emerged.

In 1845, three boys at Rugby school were tasked with codifying the rules then being used at the school. These were the first set of written rules (or code) for any form of football. This further assisted the spread of the Rugby game. For instance, Dublin University Football Club — founded at Trinity College, Dublin in 1854 and later famous as a bastion of the Rugby School game — is the world's oldest documented football club in any code.

Competitions

The longest running football fixture is the Cordner-Eggleston Cup, contested between Melbourne Grammar School and Scotch College, Melbourne every year since 1858. It is believed by many to also be the first match of Australian rules football, although it was played under experimental rules in its first year. The first football trophy tournament was the Caledonian Challenge Cup, donated by the Royal Caledonian Society of Melbourne, played in 1861 under the Melbourne Rules. The oldest football league is a rugby football competition, the United Hospitals Challenge Cup (1874), while the oldest rugby trophy is the Rugby League Challenge Cup (1897). The South Australian Football Association (30th April 1877) is the oldest surviving Australian rules football competition. The The Football League (1888) is recognised as the longest running Association Football league, while the oldest trophy is the FA Cup, while the oldest national trophy in soccer is the Scottish Cup (1874).

Establishment of modern codes

English public schools

While football continued to be played in various forms throughout Britain, its public schools (known as private schools in other countries) are widely credited with four key achievements in the creation of modern football codes. First of all, the evidence suggests that they were important in taking football away from its "mob" form and turning it into an organised team sport. Second, many early descriptions of football and references to it were recorded by people who had studied at these schools. Third, it was teachers, students and former students from these schools who first codified football games, to enable matches to be played between schools. Finally, it was at English public schools that the division between "kicking" and "running" (or "carrying") games first became clear.

The earliest evidence that games resembling football were being played at English public schools — mainly attended by boys from the upper, upper-middle and professional classes — comes from the Vulgaria by William Horman in 1519. Horman had been headmaster at Eton and Winchester colleges and his Latin textbook includes a translation exercise with the phrase "We wyll playe with a ball full of wynde".

Richard Mulcaster, a student at Eton College in the early 16th century and later headmaster at other English schools, has been described as “the greatest sixteenth Century advocate of football”. Among his contributions are the earliest evidence of organised team football. Mulcaster's writings refer to teams ("sides" and "parties"), positions ("standings"), a referee ("judge over the parties") and a coach "(trayning maister)". Mulcaster's "footeball" had evolved from the disordered and violent forms of traditional football:

[s]ome smaller number with such overlooking, sorted into sides and standings, not meeting with their bodies so boisterously to trie their strength: nor shouldring or shuffing one an other so barbarously ... may use footeball for as much good to the body, by the chiefe use of the legges.

In 1633, David Wedderburn, a teacher from Aberdeen, mentioned elements of modern football games in a short Latin textbook called "Vocabula." Wedderburn refers to what has been translated into modern English as "keeping goal" and makes an allusion to passing the ball ("strike it here"). There is a reference to "get hold of the ball," suggesting that some handling was allowed. It is clear that the tackles allowed included the charging and holding of opposing players ("drive that man back").

A more detailed description of football is given in Francis Willughby's Book of Games, written in about 1660. Willughby, who had studied at Sutton Coldfield School, is the first to describe goals and a distinct playing field: "a close that has a gate at either end. The gates are called Goals." His book includes a diagram illustrating a football field. He also mentions tactics ("leaving some of their best players to guard the goal"); scoring ("they that can strike the ball through their opponents' goal first win") and the way teams were selected ("the players being equally divided according to their strength and nimbleness"). He is the first to describe a "law" of football: "they must not strike [an opponent's leg] higher than the ball"

English public schools also devised the first offside rules, during the late 18th century. In the earliest manifestations of these rules, players were "off their side" if they simply stood between the ball and the goal which was their objective. Players were not allowed to pass the ball forward, either by foot or by hand. They could only dribble with their feet, or advance the ball in a scrum or similar formation. However, offside laws began to diverge and develop differently at the each school, as is shown by the rules of football from Winchester, Rugby, Harrow and Cheltenham, during in the period of 1810–1850.

By the early 19th century, (before the Factory Act of 1850), most working class people in Britain had to work six days a week, often for over twelve hours a day. They had neither the time nor the inclination to engage in sport for recreation and, at the time, many children were part of the labour force. Feast day football played on the streets was in decline. Public school boys, who enjoyed some freedom from work, became the inventors of organised football games with formal codes of rules.

Football was adopted by a number of public schools as a way of encouraging competitiveness and keeping youths fit. Each school drafted its own rules, which varied widely between different schools and were changed over time with each new intake of pupils. Two schools of thought developed regarding rules. Some schools favoured a game in which the ball could be carried (as at Rugby, Marlborough and Cheltenham), while others preferred a game where kicking and dribbling the ball was promoted (as at Eton, Harrow, Westminster and Charterhouse). The division into these two camps was partly the result of circumstances in which the games were played. For example, Charterhouse and Westminster at the time had restricted playing areas; the boys were confined to playing their ball game within the school cloisters, making it difficult for them to adopt rough and tumble running games.

Rugby School

William Webb Ellis, a pupil at Rugby School, is said to have "with a fine disregard for the rules of football, as played in his time [emphasis added], first took tha ball in his arms and ran with it, thus creating the distinctive feature of the rugby game." in 1823. This act is usually said to be the beginning of Rugby football, but there is little evidence that it occurred, and most sports historians believe the story to be apocryphal. The act of 'taking the ball in is arms' is often misinterpreted as 'picking the ball up' as it is widley believed that Webb Ellis' 'crime' was handling the ball, as in modern soccer, however handling the ball as the time was often permitted and in some cases compulsory, the rule for which Webb Ellis showed disregard was running forward with it as the rules of his time only allowed a player to retreat backwards or kick forwards.

The boom in rail transport in Britain during the 1840s meant that people were able to travel further and with less inconvenience than they ever had before. Inter-school sporting competitions became possible. However, it was difficult for schools to play each other at football, as each school played by its own rules. The solution to this problem was usually that the match be divided into two halves, one half played by the rules of the host "home" school, and the other half by the visiting "away" school.

Apart from Rugby football, the public school codes have barely been played beyond the confines of each school's playing fields. However, many of them are still played at the schools which created them (see Surviving public school games below).

Football History

Early history

Ancient games

The Ancient Greeks and Romans are known to have played many ball games, some of which involved the use of the feet. The Roman game harpastum is believed to have been adapted from a team game known as "επισκυρος" (episkyros) or phaininda, which is mentioned by a Greek playwright, Antiphanes (388–311 BC) and later referred to by the Christian theologian Clement of Alexandria (c.150-c.215 AD). The Roman politician Cicero (106-43 BC) describes the case of a man who was killed whilst having a shave when a ball was kicked into a barber's shop. These games appears to have resembled rugby football. Roman ball games already knew the air-filled ball, the follis. activity resembling football can be found in the Chinese military manual Zhan Guo Ce compiled between the 3rd century and 1st century BC. describes a practice known as cuju (蹴鞠, literally "kick ball"), which originally involved kicking a leather ball through a small hole in a piece of silk cloth which was fixed on bamboo canes and hung about 9 m above ground. During the Han Dynasty (206 BC–220 AD), cuju games were standardized and rules were established. Variations of this game later spread to Japan and Korea, known as kemari and chuk-guk respectively. By the Chinese Tang Dynasty (618–907), the feather-stuffed ball was replaced by an air-filled ball and cuju games had become professionalized, with many players making a living playing cuju.^{[citation needed]} Also, two different types of goal posts emerged: One was made by setting up posts with a net between them and the other consisted of just one goal post in the middle of the field.

The Japanese version of cuju is kemari (蹴鞠), and was developed during the Asuka period. This is known to have been played within the Japanese imperial court in Kyoto from about 600 AD. In kemari several people stand in a circle and kick a ball to each other, trying not to let the ball drop to the ground (much like keepie uppie). The game appears to have died out sometime before the mid-19th century. It was revived in 1903 and is now played at a number of festivals.

There are a number of references to traditional, ancient, and/or prehistoric ball games, played by indigenous peoples in many different parts of the world. For example, in 1586, men from a ship commanded by an English explorer named John Davis, went ashore to play a form of football with Inuit (Eskimo) people in Greenland. There are later accounts of an Inuit game played on ice, called Aqsaqtuk. Each match began with two teams facing each other in parallel lines, before attempting to kick the ball through each other team's line and then at a goal. In 1610, William Strachey of the Jamestown settlement, Virginia recorded a game played by Native Americans, called Pahsaheman. In Victoria, Australia, indigenous people played a game called Marn Grook ("ball game"). An 1878 book by Robert Brough-Smyth, The Aborigines of Victoria, quotes a man called Richard Thomas as saying, in about 1841, that he had witnessed Aboriginal people playing the game: "Mr Thomas describes how the foremost player will drop kick a ball made from the skin of a possum and how other players leap into the air in order to catch it." It is widely believed that Marn Grook had an influence on the development of Australian rules football (see below).

Games played in Central America with rubber balls by indigenous peoples are also well-documented as existing since before this time, but these had more similarities to basketball or volleyball, and since their influence on modern football games is minimal, most do not class them as football.

These games and others may well go far back into antiquity and may have influenced later football games. However, the main sources of modern football codes appear to lie in western Europe, especially England.

Medieval and early modern Europe

The Middle Ages saw a huge rise in popularity of annual Shrovetide football matches throughout Europe, particularly in England. The game played in England at this time may have arrived with the Roman occupation, but the only pre-Norman reference is to boys playing "ball games" in the ninth century Historia Brittonum. Reports of a game played in Brittany, Normandy, and Picardy, known as La Soule or Choule, suggest that some of these football games could have arrived in England as a result of the Norman Conquest.

An illustration of so-called "mob football".

These forms of football, sometimes referred to as "mob football", would be played between neighbouring towns and villages, involving an unlimited number of players on opposing teams, who would clash in a heaving mass of people, struggling to move an item such as an inflated pig's bladder, to particular geographical points, such as their opponents' church. Shrovetide games have survived into the modern era in a number of English towns (see below).

The first detailed description of football in England was given by William FitzStephen in about 1174–1183. He described the activities of London youths during the annual festival of Shrove Tuesday:

After lunch all the youth of the city go out into the fields to take part in a ball game. The students of each school have their own ball; the workers from each city craft are also carrying their balls. Older citizens, fathers, and wealthy citizens come on horseback to watch their juniors competing, and to relive their own youth vicariously: you can see their inner passions aroused as they watch the action and get caught up in the fun being had by the carefree adolescents

Most of the very early references to the game speak simply of "ball play" or "playing at ball". This reinforces the idea that the games played at the time did not necessarily involve a ball being kicked.

The earliest reference to a ball game that involved kicking comes from 1280 at Ulgham, Northumberland, England in which a player was killed as a result of running against an opposing player's dagger. A similar episode occurred in Shouldham, Norfolk, England in 1321: "[d]uring the game at ball as he kicked the ball, a lay friend of his... ran against him and wounded himself".

In 1314, Nicholas de Farndone, Lord Mayor of the City of London issued a decree banning football in the French used by the English upper classes at the time. A translation reads: "[f]orasmuch as there is great noise in the city caused by hustling over large foot balls [rageries de grosses pelotes de pee] in the fields of the public from which many evils might arise which God forbid: we command and forbid on behalf of the king, on pain of imprisonment, such game to be used in the city in the future." This is the earliest reference to football.

In 1363, King Edward III of England issued a proclamation banning "...handball, football, or hockey; coursing and cock-fighting, or other such idle games", showing that "football" — whatever its exact form in this case — was being differentiated from games involving other parts of the body, such as handball.

King Henry IV of England also presented one of the earliest documented uses of the English word "football", in 1409, when he issued a proclamation forbidding the levying of money for "foteball".

There is also an account in Latin from the end of the 15th century of football being played at Cawston, Nottinghamshire. This is the first description of a "kicking game" and the first description of dribbling: "[t]he game at which they had met for common recreation is called by some the foot-ball game. It is one in which young men, in country sport, propel a huge ball not by throwing it into the air but by striking it and rolling it along the ground, and that not with their hands but with their feet... kicking in opposite directions" The chronicler gives the earliest reference to a football field, stating that: "[t]he boundaries have been marked and the game had started.

Other firsts in the mediæval and early modern eras:

• "a football", in the sense of a ball rather than a game, was first mentioned in 1486. This reference is in Dame Juliana Berners' Book of St Albans. It states: "a certain rounde instrument to play with ...it is an instrument for the foote and then it is calde in Latyn 'pila pedalis', a fotebal."
• a pair of football boots was ordered by King Henry VIII of England in 1526.
• women playing a form of football was in 1580, when Sir Philip Sidney described it in one of his poems: "[a] tyme there is for all, my mother often sayes, When she, with skirts tuckt very hy, with girles at football playes."
• the first references to goals are in the late 16th and early 17th centuries. In 1584 and 1602 respectively, John Norden and Richard Carew referred to "goals" in Cornish hurling. Carew described how goals were made: "they pitch two bushes in the ground, some eight or ten foote asunder; and directly against them, ten or twelue [twelve] score off, other twayne in like distance, which they terme their Goales". He is also the first to describe goalkeepers and passing of the ball between players.
• the first direct reference to scoring a goal is in John Day's play The Blind Beggar of Bethnal Green (performed circa 1600; published 1659): "I'll play a gole at camp-ball" (an extremely violent variety of football, which was popular in East Anglia). Similarly in a poem in 1613, Michael Drayton refers to "when the Ball to throw, And drive it to the Gole, in squadrons forth they goe".

Calcio Fiorentino

An illustration of the Calcio Fiorentino field and starting positions, from a 1688 book by Pietro di Lorenzo Bini.

In the 16th century, the city of Florence celebrated the period between Epiphany and Lent by playing a game which today is known as "calcio storico" ("historic kickball") in the Piazza della Novere or the Piazza Santa Croce. The young aristocrats of the city would dress up in fine silk costumes and embroil themselves in a violent form of football. For example, calcio players could punch, shoulder charge, and kick opponents. Blows below the belt were allowed. The game is said to have originated as a military training exercise. In 1580, Count Giovanni de' Bardi di Vernio wrote Discorso sopra 'l giuoco del Calcio Fiorentino. This is sometimes said to be the earliest code of rules for any football game. The game was not played after January 1739 (until it was revived in May 1930).

Official disapproval and attempts to ban football

Numerous attempts have been made to ban football games, particularly the most rowdy and disruptive forms. This was especially the case in England and in other parts of Europe, during the Middle Ages and early modern period. Between 1324 and 1667, football was banned in England alone by more than 30 royal and local laws. The need to repeatedly proclaim such laws demonstrated the difficulty in enforcing bans on popular games. King Edward II was so troubled by the unruliness of football in London that on April 13, 1314 he issued a proclamation banning it: "Forasmuch as there is great noise in the city caused by hustling over large balls from which many evils may arise which God forbid; we command and forbid, on behalf of the King, on pain of imprisonment, such game to be used in the city in the future."

The reasons for the ban by Edward III, on June 12, 1349, were explicit: football and other recreations distracted the populace from practicing archery, which was necessary for war.

By 1608, the local authorities in Manchester were complaining that: "With the ffotebale...[there] hath beene greate disorder in our towne of Manchester we are told, and glasse windowes broken yearlye and spoyled by a companie of lewd and disordered persons ..." That same year, the word "football" was used disapprovingly by William Shakespeare. Shakespeare's play King Lear contains the line: "Nor tripped neither, you base football player" (Act I, Scene 4). Shakespeare also mentions the game in A Comedy of Errors (Act II, Scene 1):

Am I so round with you as you with me,

That like a football you do spurn me thus?

You spurn me hence, and he will spurn me hither:

If I last in this service, you must case me in leather.

"Spurn" literally means to kick away, thus implying that the game involved kicking a ball between players.

King James I of England's Book of Sports (1618) however, instructs Christians to play at football every Sunday afternoon after worship. The book's aim appears to be an attempt to offset the strictness of the Puritans regarding the keeping of the Sabbath.

Football

Football is the word given to a number of similar team sports, all of which involve (to varying degrees) kicking a ball with the foot in an attempt to score a goal (. The most popular of these sports world-wide is association football, also known as "soccer" and most commonly just "football". The English language word "football" is also applied to gridiron football (which includes games like American football and Canadian football), Australian rules football, Gaelic football, rugby footballrugby league and rugby union), and related games. Each of these codes (specific sets of rules, or the games defined by them) is referred to as "football".

These games involve:

• two teams of usually between 11 and 18 players.

. Note that versions of the base games with fewer players have varying degrees of popularity:

• • Six-man, eight-man, and nine-man football, derived from American football, are also played mainly at scholastic level in less-populated parts of the United States. Small schools in the Canadian province of Saskatchewan also play nine-man football, derived from the country's own code.
  • Rugby sevens, a version of rugby union with seven players per side instead of 15, is especially well-developed, with its own World Cup, a prominent annual international competition, and an entrenched position in the Commonwealth Games.
  • Although the sevens format also exists in rugby league, a different abbreviated format, rugby league nines, is more popular.
• a clearly defined area in which to play the game;
• scoring goals and/or points, by moving the ball to an opposing team's end of the field and either into a goal area, or over a line;
• the goal and/or line being defended by the opposing team;
• players being required to move the ball—depending on the code—by kicking, carrying and/or hand passing the ball; and
• goals and/or points resulting from players putting the ball between two goalposts.

In most codes, there are rules restricting the movement of players offside, and players scoring a goal must put the ball either under or over a crossbar between the goalposts. Other features common to several football codes include: points being mostly scored by players carrying the ball across the goal line and; players receiving a free kick after they take a mark/make a fair catch.

Peoples from around the world have played games which involved kicking and/or carrying a ball, since ancient times. However, most of the modern codes of football have their origins in England.
