The Portella della Ginestra massacre was one of the most violent acts in the history of modern Italian politics, when 11 people were killed and 27 wounded during May Day celebrations in Sicily on May 1, 1947, in the municipality of Piana degli Albanesi. Those held responsible were the bandit and separatist leader Salvatore Giuliano and his gang – although their motives and intentions are still a matter of controversy.
