The Fédération internationale de football association is an international self-regulatory governing body of association football, beach soccer, and futsal. It was founded in 1904 to oversee international competition among the national associations of Belgium, Denmark, France, Germany, the Netherlands, Spain, Sweden, and Switzerland. Headquartered in Zürich, Switzerland, its membership now comprises 211 national associations. These national associations must also be members of one of the six regional confederations into which the world is divided: CAF (Africa), AFC, UEFA (Europe), CONCACAF, OFC (Oceania), and CONMEBOL.

Association football, commonly known as football, or soccer, is a team sport played between two teams of 11 players each, who primarily use their feet to propel a ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing team. 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 and territories, it is the world's most popular sport.
