Australian rules football was heavily affected by both World War I and World War II. Hundreds of leading players served their country abroad, and many lost their lives. On the home front, competitions like the Victorian Football League (VFL) went ahead during these wars, but faced many restrictions.
In March 1915, the VFL voted on whether or not to suspend the 1915 season, but voted in favour of playing by 13 votes to four. The season began on 24 April, the day before Australian troops landed at Gallipoli. Attendances were poor throughout the year.
St Kilda changed their club colours because their traditional red, white and black colours were the same as the German Empire. Their new colours of black, red and yellow were chosen as support to Australia's ally Belgium, where a group of St Kilda players were serving.
The 1916 season was heavily affected by the war. Only four clubs, Carlton, Collingwood, Fitzroy and Richmond, competed in the league. The other clubs withdrew from the competition, both out of Australian patriotism and as a result of player shortage. Despite finishing the home and away season in last place, Fitzroy won the Grand Final that year.
Both Geelong and South Melbourne returned to the league in 1917, while St Kilda and Essendon made their comeback in 1918. Melbourne spent the longest time out of the league, missing three seasons before rejoining the VFL in 1919.
