around a rectangular field called a pitch. The objective of the game is to score more goals than the opposition by moving the ball beyond the goal line into a rectangular framed goal defended by the opposing side. Traditionally, the game has been played over two 45 minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries, it is considered the world's most popular sport. The game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 with the International Football Association Board (IFAB) maintaining them since 1886.

When the ball is in play, the players mainly use their feet, but may use any other part of their body to control, strike or pass the ball apart from their hands or arms. Only the goalkeepers may use their hands and arms, and only then within the penalty area. The team that has scored more goals at the end of the game is the winner.

Name

Football is one of a family of football codes, which emerged from various ball games played worldwide since antiquity. Within the English-speaking world, association football is now usually called "football" in Great Britain and most of Ulster in the north of Ireland, whereas people usually call it "soccer" in regions and countries where other codes of football are prevalent, such as

, the game is also primarily called sakkā (サッカー), derived from "soccer". The term ''soccer'' comes from Oxford "-er" slang, which was prevalent at the University of Oxford in England from about 1875, and is thought to have been borrowed from the slang of Rugby School. Initially spelled ''assoccer'', it was later reduced to the modern spelling. This form of slang also gave rise to ''rugger'' for rugby football, ''fiver'' and ''tenner'' for five pound and ten pound notes, and the now-archaic ''footer'' that was also a name for association football. The word ''soccer'' arrived at its final form in 1895 and was first recorded in 1889 in the earlier form of ''socca.''

in Great Queen Street, London. The only school to be represented on this occasion was Charterhouse. The Freemasons' Tavern was the setting for five more meetings between October and December, which eventually produced the first comprehensive set of rules. At the final meeting, the first FA treasurer, the representative from Blackheath F.C., withdrew his club from the FA over the removal of two draft rules at the previous meeting: the first allowed for running with the ball in hand; the second for obstructing such a run by hacking (kicking an opponent in the shins), tripping and holding. Other English rugby clubs followed this lead and did not join the FA, and instead in 1871 formed the

. The eleven remaining clubs, under the charge of Ebenezer Cobb Morley, went on to ratify the original thirteen laws of the game. These rules included handling of the ball by "marks" and the lack of a crossbar, rules which made it remarkably similar to Victorian rules football being developed at that time in Australia. The Sheffield FA played by its own rules until the 1870s, with the FA absorbing some of its rules until there was little difference between the games. The world's oldest football competition is the FA Cup, which was founded by the footballer and cricketer Charles W. Alcock, and has been contested by English teams since 1872.

The growing popularity of the international game led to the admittance of FIFA representatives to the IFAB in 1913. The board consists of four representatives from FIFA and one representative from each of the four British associations. Football is played at a professional level all over the world. Millions of people regularly go to football stadiums to follow their favourite teams, while billions more watch the game on television or on the internet. A very large number of people also play football at an amateur level. According to a survey conducted by FIFA published in 2001, over 240 million people from more than 200 countries regularly play football. Football has the highest global television audience in sport. In many parts of the world, football evokes great passions and plays an important role in the life of individual fans, local communities, and even nations. Ryszard Kapuściński says that Europeans who are polite, modest, or humble fall easily into rage when playing or watching football games. The Ivory Coast national football team helped secure a truce to the nation's civil war in 2006 and it helped further reduce tensions between government and rebel forces in 2007 by playing a match in the rebel capital of Bouaké, an occasion that brought both armies together peacefully for the first time.

Women's association football


Early women's football

Women may have been playing "football" for as long as the game has existed. Evidence shows that an ancient version of the game ( Tsu Chu) was played by women during the Han dynasty (25–220 CE). Two female figures are depicted in Han dynasty (25–220 CE) frescoes, playing Tsu Chu. There are, however, a number of opinions about the accuracy of dates, the earliest estimates at 5000 BCE. Association football, the modern game, also has documented early involvement of women. An annual competition in Mid-Lothian, Scotland during the 1790s is reported, too. In 1863, football governing bodies introduced standardised rules to prohibit violence on the pitch, making it more socially acceptable for women to play. The first match recorded by the

took place in 1892 in Glasgow. In England, the first recorded game of football between women took place in 1895. The best-documented early European team was founded by activist Nettie Honeyball in England in 1894. It was named the British Ladies' Football Club. Nettie Honeyball is quoted as, "I founded the association late last year 894 with the fixed resolve of proving to the world that women are not the 'ornamental and useless' creatures men have pictured. I must confess, my convictions on all matters where the sexes are so widely divided are all on the side of emancipation, and I look forward to the time when ladies may sit in Parliament and have a voice in the direction of affairs, especially those which concern them most." Honeyball and those like her paved the way for women's football. However, the women's game was frowned upon by the British football associations and continued without their support. It has been suggested that this was motivated by a perceived threat to the 'masculinity' of the game. Women's football became popular on a large scale at the time of the First World War, when employment in heavy industry spurred the growth of the game, much as it had done for men 50 years earlier. The most successful team of the era was Dick, Kerr Ladies F.C. of Preston, England. The team played in the first women's international matches in 1920, against a team from Paris, France, in April, and also made up most of the England team against a

Ladies XI in 1920, and winning 22–0. Despite being more popular than some men's football events (one match saw a 53,000 strong crowd), women's football in England suffered a blow in 1921 when The Football Association outlawed the playing of the game on Association members' pitches, on the grounds that the game (as played by women) was distasteful. Some speculated that this may have also been due to envy of the large crowds that women's matches attracted. This led to the formation of the
English Ladies Football Association The English Ladies' Football Association (ELFA) was formed in 1921 and active until 1922. It was arguably a direct response to the Football Association (FA)’s ban on women's football teams. The first meeting of the ELFA was held several weeks a ...
and play moved to rugby grounds. Association football has been played by women since at least the time of the first recorded women's games in the late 19th century. It has traditionally been associated with charity games and physical exercise, particularly in the United Kingdom. In the late 1960s and early 1970s, women's association football was organised in the United Kingdom, eventually becoming the most prominent team sport for British women.


20th and 21st century

The growth in women's football has seen major competitions being launched at both national and international level mirroring the male competitions. Women's football has faced many struggles. It had a "golden age" in the United Kingdom in the early 1920s when crowds reached 50,000 at some matches; this was stopped on 5 December 1921 when England's Football Association voted to ban the game from grounds used by its member clubs. The FA's ban was rescinded in December 1969 with UEFA voting to officially recognise women's football in 1971. The

restart. Although players usually use their feet to move the ball around they may use any part of their body (notably, "heading" with the forehead) other than their hands or arms. Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though players may not pass to teammates who are in an offside position. During gameplay, players attempt to create goal-scoring opportunities through individual control of the ball, such as by dribbling, passing the ball to a teammate, and by taking shots at the goal, which is guarded by the opposing goalkeeper. Opposing players may try to regain control of the ball by intercepting a pass or through tackling the opponent in possession of the ball; however, physical contact between opponents is restricted. Football is generally a free-flowing game, with play stopping only when the ball has left the field of play or when play is stopped by the

for an infringement of the rules. After a stoppage, play recommences with a specified restart. At a professional level, most matches produce only a few goals. For example, the 2005–06 season of the English Premier League produced an average of 2.48 goals per match. The Laws of the Game do not specify any player positions other than goalkeeper, but a number of specialised roles have evolved. Broadly, these include three main categories: strikers, or forwards, whose main task is to score goals; defenders, who specialise in preventing their opponents from scoring; and midfielders, who dispossess the opposition and keep possession of the ball to pass it to the forwards on their team. Players in these positions are referred to as outfield players, to distinguish them from the goalkeeper. These positions are further subdivided according to the area of the field in which the player spends the most time. For example, there are central defenders and left and right midfielders. The ten outfield players may be arranged in any combination. The number of players in each position determines the style of the team's play; more forwards and fewer defenders creates a more aggressive and offensive-minded game, while the reverse creates a slower, more defensive style of play. While players typically spend most of the game in a specific position, there are few restrictions on player movement, and players can switch positions at any time. The layout of a team's players is known as a '' formation''. Defining the team's formation and tactics is usually the prerogative of the team's manager.


Laws

There are 17 laws in the official Laws of the Game, each containing a collection of stipulation and guidelines. The same laws are designed to apply to all levels of football, although certain modifications for groups such as juniors, seniors, women and people with physical disabilities are permitted. The laws are often framed in broad terms, which allow flexibility in their application depending on the nature of the game. The Laws of the Game are published by FIFA, but are maintained by the IFAB. In addition to the seventeen laws, numerous IFAB decisions and other directives contribute to the regulation of association football. Within the United States,

used a distinct ruleset during the 1990s and the National Federation of State High School Associations and National Collegiate Athletic Association still use rulesets that are comparable to, but different from, the IFAB Laws.


Players, equipment, and officials

Each team consists of a maximum of eleven players (excluding substitutes), one of whom must be the goalkeeper. Competition rules may state a minimum number of players required to constitute a team, which is usually seven. Goalkeepers are the only players allowed to play the ball with their hands or arms, provided they do so within the penalty area in front of their own goal. Though there are a variety of positions in which the outfield (non-goalkeeper) players are strategically placed by a coach, these positions are not defined or required by the Laws. The basic equipment or ''

is not a required piece of basic equipment, but players today may choose to wear it to protect themselves from head injury. Players are forbidden to wear or use anything that is dangerous to themselves or another player, such as jewellery or watches. The goalkeeper must wear clothing that is easily distinguishable from that worn by the other players and the match officials. A number of players may be replaced by substitutes during the course of the game. The maximum number of substitutions permitted in most competitive international and domestic league games is three in ninety minutes with each team being allowed one more if the game should go into extra-time, though the permitted number may vary in other competitions or in friendly matches. Common reasons for a substitution include injury, tiredness, ineffectiveness, a tactical switch, or timewasting at the end of a finely poised game. In standard adult matches, a player who has been substituted may not take further part in a match. IFAB recommends "that a match should not continue if there are fewer than seven players in either team". Any decision regarding points awarded for abandoned games is left to the individual football associations. A game is officiated by a
referee A referee is an official, in a variety of sports and competition, responsible for enforcing the rules of the sport, including sportsmanship decisions such as ejection. The official tasked with this job may be known by a variety of other titl ...
, who has "full authority to enforce the Laws of the Game in connection with the match to which he has been appointed" (Law 5), and whose decisions are final. The referee is assisted by two assistant referees. In many high-level games there is also a fourth official who assists the referee and may replace another official should the need arise. Goal line technology is used to measure if the whole ball has crossed the goal-line thereby determining whether a goal has been scored or not; this was brought in to prevent controversy. Video assistant referees (VAR) have also been increasingly introduced in high-level matches to assist officials through video replays to correct clear and obvious mistakes. There are four types of calls that can be reviewed: mistaken identity in awarding a red or yellow card, goals and whether there was a violation during the buildup, direct red card decisions, and penalty decisions.


Ball

The ball is spherical with a circumference of between , a weight in the range of , and a pressure between at sea level. In the past the ball was made up of leather panels sewn together, with a latex bladder for pressurisation but modern balls at all levels of the game are now synthetic.


Pitch

As the Laws were formulated in England, and were initially administered solely by the four British football associations within IFAB, the standard dimensions of a football pitch were originally expressed in imperial units. The Laws now express dimensions with approximate metric equivalents (followed by traditional units in brackets), though use of imperial units remains popular in English-speaking countries with a relatively recent history of metrication (or only partial metrication), such as Britain. The length of the pitch, or field, for international adult matches is in the range of and the width is in the range of . Fields for non-international matches may be length and in width, provided that the pitch does not become square. In 2008, the IFAB initially approved a fixed size of long and wide as a standard pitch dimension for international matches; however, this decision was later put on hold and was never actually implemented. The longer boundary lines are ''touchlines'', while the shorter boundaries (on which the goals are placed) are ''goal lines''. A rectangular goal is positioned on each goal line, midway between the two touchlines. The inner edges of the vertical goal posts must be apart, and the lower edge of the horizontal crossbar supported by the goal posts must be above the ground. Nets are usually placed behind the goal, but are not required by the Laws. In front of the goal is the penalty area. This area is marked by the goal line, two lines starting on the goal line from the goalposts and extending into the pitch perpendicular to the goal line, and a line joining them. This area has a number of functions, the most prominent being to mark where the goalkeeper may handle the ball and where a penalty foul by a member of the defending team becomes punishable by a penalty kick. Other markings define the position of the ball or players at kick-offs, goal kicks, penalty kicks and corner kicks.


Duration and tie-breaking methods


90-minute ordinary time

A standard adult football match consists of two halves of 45 minutes each. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called ''additional time'' in FIFA documents, but is most commonly referred to as ''stoppage time'' or ''injury time'', while ''lost time'' can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. Stoppage time does not fully compensate for the time in which the ball is

, and a 90-minute game typically involves about an hour of "effective playing time". The referee alone signals the end of the match. In matches where a fourth official is appointed, towards the end of the half, the referee signals how many minutes of stoppage time they intend to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and

. Trailing 1–0 with two minutes remaining, Stoke were awarded a penalty kick. Villa's goalkeeper deliberately kicked the ball out of play; by the time it was recovered, the clock had run out and the game was over, leaving Stoke unable to attempt the penalty. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed; thus, no game can end with an un-completed penalty.


Tie-breaking

In league competitions, games may end in a draw. In knockout competitions where a winner is required various methods may be employed to break such a deadlock; some competitions may invoke replays. A game tied at the end of regulation time may go into extra time, which consists of two further 15-minute periods. If the score is still tied after extra time, some competitions allow the use of penalty shootouts (known officially in the Laws of the Game as "kicks from the penalty mark") to determine which team will progress to the next stage of the tournament. Goals scored during extra time periods count towards the final score of the game, but kicks from the penalty mark are only used to decide the team that progresses to the next part of the tournament (with goals scored in a penalty shootout not making up part of the final score). In competitions using two-legged matches, each team competes at home once, with an aggregate score from the two matches deciding which team progresses. Where aggregates are equal, the

may be used to determine the winners, in which case the winner is the team that scored the most goals in the leg they played away from home. If the result is still equal, extra time and potentially a penalty shootout are required.


Ball in and out of play

Under the Laws, the two basic states of play during a game are ''ball in play'' and ''ball out of play''. From the beginning of each playing period with a kick-off until the end of the playing period, the ball is in play at all times, except when either the ball leaves the field of play, or play is stopped by the referee. When the ball becomes out of play, play is restarted by one of eight restart methods depending on how it went out of play: *

: when the ball has crossed the touchline; awarded to the opposing team to that which last touched the ball. * Goal kick: when the ball has wholly crossed the goal line without a goal having been scored and having last been touched by a player of the attacking team; awarded to defending team. * Corner kick: when the ball has wholly crossed the goal line without a goal having been scored and having last been touched by a player of the defending team; awarded to attacking team. * Indirect free kick: awarded to the opposing team following "non-penal" fouls, certain technical infringements, or when play is stopped to caution or dismiss an opponent without a specific foul having occurred. A goal may not be scored directly (without the ball first touching another player) from an indirect free kick. * Direct free kick: awarded to fouled team following certain listed "penal" fouls. A goal may be scored directly from a direct free kick. * Penalty kick: awarded to the fouled team following a foul usually punishable by a direct free kick but that has occurred within their opponent's penalty area. * Dropped-ball: occurs when the referee has stopped play for any other reason, such as a serious injury to a player, interference by an external party, or a ball becoming defective.


Misconduct


On-field

A foul occurs when a player commits an offence listed in the Laws of the Game while the ball is in play. The offences that constitute a foul are listed in Law 12. Handling the ball deliberately, tripping an opponent, or pushing an opponent, are examples of "penal fouls", punishable by a direct free kick or penalty kick depending on where the offence occurred. Other fouls are punishable by an indirect free kick. The referee may punish a player's or substitute's misconduct by a caution ( yellow card) or dismissal (
red card A red card is a type of penalty card that is shown in many sports after a rules infraction. Red card may also refer to: Art, entertainment, and media * ''Red Card'' (album), 1976 release by Streetwalkers * Red card, suit (cards) of hearts or dia ...
). A second yellow card in the same game leads to a red card, which results in a dismissal. A player given a yellow card is said to have been "booked", the referee writing the player's name in their official notebook. If a player has been dismissed, no substitute can be brought on in their place and the player may not participate in further play. Misconduct may occur at any time, and while the offences that constitute misconduct are listed, the definitions are broad. In particular, the offence of "unsporting behaviour" may be used to deal with most events that violate the spirit of the game, even if they are not listed as specific offences. A referee can show a yellow or red card to a player, substitute or substituted player. Non-players such as managers and support staff cannot be shown the yellow or red card but may be expelled from the technical area if they fail to conduct themselves in a responsible manner. Rather than stopping play, the referee may allow play to continue if doing so will benefit the team against which an offence has been committed. This is known as "playing an advantage". The referee may "call back" play and penalise the original offence if the anticipated advantage does not ensue within "a few seconds". Even if an offence is not penalised due to advantage being played, the offender may still be sanctioned for misconduct at the next stoppage of play. The referee's decision in all on-pitch matters is considered final. The score of a match cannot be altered after the game, even if later evidence shows that decisions (including awards/non-awards of goals) were incorrect.


Off-field

Along with the general administration of the sport, football associations and competition organisers also enforce good conduct in wider aspects of the game, dealing with issues such as comments to the press, clubs' financial management, doping, age fraud and
match fixing In organized sports, match fixing is the act of playing or officiating a match with the intention of achieving a pre-determined result, violating the rules of the game and often the law. There are many reasons why match fixing might take place, ...
. Most competitions enforce mandatory suspensions for players who are sent off in a game.For example, see The Football Association's rules regarding player suspensions in FA competitions: Some on-field incidents, if considered very serious (such as allegations of racial abuse), may result in competitions deciding to impose heavier sanctions than those normally associated with a red card. Some associations allow for appeals against player suspensions incurred on-field if clubs feel a referee was incorrect or unduly harsh. Sanctions for such infractions may be levied on individuals or on to clubs as a whole. Penalties may include fines, points deductions (in league competitions) or even expulsion from competitions. For example, the English Football League deduct 12 points from any team that enters financial administration. Among other administrative sanctions are penalties against game forfeiture. Teams that had forfeited a game or had been forfeited against would be awarded a technical loss or win.

International competitions

International competitions in association football principally consist of two varieties: competitions involving representative national teams or those involving clubs based in multiple nations and national leagues. ''International football'', without qualification, most often refers to the former. In the case of international club competition, it is the country of origin of the clubs involved, not the nationalities of their players, that renders the competition international in nature. The major international competition in football is the World Cup, organised by FIFA. This competition takes place every four years since

Domestic competitions

The governing bodies in each country operate league systems in a domestic season, normally comprising several divisions, in which the teams gain points throughout the season depending on results. Teams are placed into tables, placing them in order according to points accrued. Most commonly, each team plays every other team in its league at home and away in each season, in a
