Australian rules football
The Melbourne Football Club was founded on 14 May 1859; the Melbourne Football Club is one of the oldest surviving football clubs in the world.  A game of football was played between Scotch College and Melbourne Grammar School. It was played over three days on an oval next to the present day Melbourne Cricket Ground, and the two schools have played an annual game ever since.  This game became known as Melbourne Rules Football, one of many local varieties of football that existed at that time, another notable one being Sheffield Rules Football. Then following its decision to not join either the association rules (1863) or rugby rules (1871), it became known as Victorian Rules, although it closely resembled the two former rule sets. Then in the 1880s as rugby and association rules began to diverge in a much greater way, Victorian Rules which resembled the 1850s type of football that both rugby and the association had based their rules on remained much the same except for moving to oval fields from rectangular fields and eventually introducing more posts.  After the sport became popular in other states, people started calling it "Australian Rules".
