Association football is the most popular sport in England, where the first modern set of rules for the code were established in 1863, which were a major influence on the development of the modern Laws of the Game. With over 40,000 association football clubs, England has more clubs involved in the code than any other country as well as the world's first club (Sheffield F.C.), the world's oldest professional association football club (Notts County), the oldest national governing body (the Football Association), the joint-first national team, the oldest national knockout competition (the FA Cup) and the oldest national league (the English Football League). Today England's top domestic league, the Premier League, is one of the most popular and richest sports leagues in the world, with six of the ten richest football clubs in the world as of 2019.
