Laws of the Game (association football) in the context of "1869 New Jersey vs. Rutgers football game"

A football pitch or soccer field is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces are allowed only to be green in colour.

All line markings on the pitch form part of the area which they define. For example, a ball on or above the touchline is still on the field of play, and a foul committed over the line bounding the penalty area results in a penalty. Therefore, a ball has to completely cross the touchline to be out of play, and a ball has to fully cross the goal line (between the goal posts) in order for a goal to be scored; if any part of the ball is still on or above the line, a goal is not scored and the ball is still in play.

Fédération Internationale de Football Association (FIFA) (lit. 'International Federation of Association Football') is an international self-regulatory governing body of association football, beach football, and futsal. It was founded on 21 May 1904 to oversee international competition among the national associations of Belgium, Denmark, France, Germany, the Netherlands, Spain, Sweden, and Switzerland. Headquartered in Zurich, Switzerland, its membership now comprises 211 national associations. These national associations must also be members of one of the six regional confederations: CAF (Africa), AFC (Asia), UEFA (Europe), CONCACAF (North & Central America and the Caribbean), OFC (Oceania), and CONMEBOL (South America).

FIFA is a sports governing body that organizes football events all over the world. FIFA outlines several objectives in its organizational statutes, including growing football internationally, ensuring it is accessible to everyone, and advocating for integrity and fair play. It is responsible for organizing and promoting football's major international tournaments, notably the World Cup which began in 1930, and the Women's World Cup which commenced in 1991. Although FIFA does not solely set the laws of the game, that being the responsibility of the International Football Association Board of which FIFA is a member, it applies and enforces the rules across all FIFA competitions. All FIFA tournaments generate revenue from sponsorships; in 2022, FIFA had revenues of over US$5.8 billion, ending the 2019–2022 cycle with a net positive of $1.2 billion, and cash reserves of over $3.9 billion.

A football or soccer ball is the ball used in the sport of association football. The ball's spherical shape, as well as its size, mass, and material composition, are specified by Law 2 of the Laws of the Game maintained by the International Football Association Board. Additional, more stringent standards are specified by FIFA and other big governing bodies for the balls used in the competitions they sanction.

Early footballs began as animal bladders or stomachs that would easily fall apart if kicked too much. Improvements became possible in the 19th century with the introduction of rubber and discoveries of vulcanization by Charles Goodyear. The modern 32-panel ball design was developed in 1962 by Eigil Nielsen, and technological research continues to develop footballs with improved performance. The 32-panel ball design was soon joined by 24-panel balls as well as 42-panel balls, both of which improved on performance prior to 2007.

During the early modern era, pupils, former pupils and teachers at English public schools developed the rules of football, eventually leading to the first written codes of football most notably the Eton College (1815) and Aldenham school (1825) football rules, and rugby football (1845). The earliest known match between two schools was Eton College v. Harrow School in 1834.

English public schools, as well as Scottish private schools, mainly attended by boys from the more affluent upper, upper-middle, and professional classes, are widely credited with three key achievements in the creation of modern codes of football. First, the evidence suggests that, during the 16th century, they transformed the popular, but violent and chaotic, "mob football" into organised team sports that were beneficial to schoolboys. Second, many early references to football in literature were recorded by people who had studied at these schools, showing they were familiar with the game. Finally, in the 19th century, former English public school boys, in a meeting organised by two old boys of Shrewsbury, were the first to write down formal codes of rules in order to enable matches to be played between different schools. These versions of football rules were the basis of both the Cambridge Rules and the subsequent rules of association football, of which only one copy survives in the library of Shrewsbury.

The captain of an association football team, sometimes known as the skipper, is a team member chosen to be the on-pitch leader of the team; they are often one of the older or more experienced members of the squad, or a player that can heavily influence a game or has good leadership qualities. The team captain is usually identified by the wearing of an armband. In the 2024/25 edition of the Laws of the Game, it was made mandatory for each team to have a captain and for each captain to be identified by the previously traditional but non-mandatory captain's armband.

In association football, an assist is a contribution leading to the scoring of a goal, where the contribution is made by someone on the scoring team other than the scorer. Statistics for assists made by players may be kept officially by the organisers of a competition, or unofficially by, for example, journalists or organisers of fantasy football competitions. Recording assists is not part of the official Laws of the Game and the criteria for an assist to be awarded may vary. Record of assists was virtually not kept at all until the end of the 20th century, although reports of matches commonly described a player as having "made" one or more goals. Since the 1990s, some leagues have kept official record of assists and based awards on them.

The separate player statistics "goals [scored]" and "assists" may be aggregated to a statistic called "[goal] contributions" or "[goal] involvements" (analogous to what is called a point in ice hockey).

Futsal is a variant of association football played between two teams of five players each on a court smaller than a football pitch. Its rules are based on the Laws of the Game of association football, and it also shares similarities with five-a-side football and indoor soccer.

Futsal is played between two teams of five players each, one of whom is the goalkeeper. The players mainly use their feet to propel a ball around the court with the objective of scoring goals against the opposing team by moving the ball beyond the goal line into the opposing team's goal. A futsal match consists of two periods of 20 minutes, and the team that scores more goals wins; an equal number of goals scored results in a draw. Futsal is played with a smaller and heavier ball than association football, and usually indoors on a hardcourt surface marked by lines.
