Members of the Melbourne Football Club codified the first rules of Australian rules football.

The Melbourne Football Club, nicknamed the Demons or colloquially the Dees, is a professional Australian rules football club based in Melbourne, Victoria, Australia. It competes in the Australian Football League (AFL), the sport's premier competition and plays its home games at the Melbourne Cricket Ground (MCG).

The laws of Australian rules football were first defined by the Melbourne Football Club in 1859 and have been amended over the years as Australian rules football evolved into its modern form. The Australian Football Council (AFC), was formed in 1905 and became responsible for the laws, although individual leagues retained a wide discretion to vary them. Following the restructure of the Victorian Football League's competition as a national competition and the League's renaming to be the Australian Football League (AFL), since 1994, the rules for the game have been maintained by the AFL through its Commission and its Competition Committee.

Australian football, also called Australian rules football or Aussie rules, or more simply football or footy, is a contact sport played between two teams of 18 players on an oval field, often a modified cricket ground. Points are scored by kicking the oval ball between the central goal posts, or between a central and outer post.
