The Battle of the Oranges is a festival in the Northern Italian city of Ivrea, which includes a tradition of throwing of oranges between organized groups. It is the largest food fight in Italy.
The festival's origins are somewhat unclear. A popular account has it that it commemorates the city's defiance against the city's tyrant, who is either a member of the Ranieri family or a conflation of the 12th-century Ranieri di Biandrate and the 13th-century Marquis William VII of Montferrat
