The rebellion known as the Sicilian Vespers took shape in 1282 when Sicilians revolted against the rule of Charles I of Anjou. This uprising was primarily caused by long-standing discontent with Angevin governance, as many Sicilians viewed Charles's regime as foreign and oppressive. The immediate spark came during a Vespers ceremony in Palermo on Easter Monday when a soldier allegedly insulted a local woman. What began as a singular incident quickly escalated into a mass uprising, with local citizens taking arms against the foreign soldiers and agents of Charles I. This event soon transformed into a widespread insurrection, with residents in various towns and cities across Sicily joining the cause. Chaos ensued as the anger towards Charles's rule was expressed violently, and thousands of Angevins were killed or expelled from the island.The rebellion led to the eventual establishment of a new monarchy in Sicily, with Peter III of Aragon being crowned as the king. This new governance was welcomed by many as it aligned more closely with Sicilian interests, compared to the oppressive nature of the Angevins. The Sicilian Vespers served as both a symbol of resistance against foreign domination and a precursor to the political realignments in the Mediterranean region. The movement not only led to a new rule in Sicily but also significantly weakened Charles I's influence and control in the area, marking a turning point in the history of Sardinia and the broader Italian political landscape. The aftermath of the conflict resulted in a prolonged series of wars and diplomatic tensions, deeply influencing Italian and Mediterranean politics for years to come.
