The Sicilian Vespers (; ) is the name given to the successful rebellion on the island of Sicily that broke out on the Easter of 1282 against the rule of the French-born king Charles I, who had ruled the Kingdom of Sicily since 1266. Within six weeks, three thousand French men and women were slain by the rebels, and the government of King Charles lost control of the island. It was the beginning of the War of the Sicilian Vespers.
