The Football Association Challenge Cup, more commonly known as the FA Cup, is an annual knockout football competition in domestic English football. First played during the 1871–72 season, it is the oldest national football competition in the world. It is organised by and named after The Football Association. Since 2015, it has been known as Emirates FA Cup after its headline sponsor Emirates. A concurrent Women's FA Cup has been held since 1970.

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.
