The Sicilian Vespers rebellion breaks out on March 30, 1282, against the oppressive rule of Charles I of Anjou, in Palermo, Sicily. Starting with a violent incident at the Santo Spirito church , it escalated into a widespread massacre of French officials and residents, effectively ending Angevin control in Sicily and leading to the Aragonese conquest.
The island ultimately broke away from Naples, leading to the establishment of a separate Sicilian kingdom under Aragonese rule (the Kingdom of Trinacria) following the Peace of Caltabellotta.
