A domestic cup (also known as association cup or national cup) is a type of sports tournament, particularly common in association football. This tournament type is notable for its participation by professional and amateur teams from many levels of a country's league system. The structure of the competition varies but is usually a knockout format and is typically organized by the country's governing body for the sport (football association).[1][2] The oldest of such tournament was England's FA Cup, first played in 1871.[3]
