Charles I of Naples - Sicilian Vespers

Sicilian Vespers

But Michael had not been working upon the military front alone. Many Ghibelline officials had fled the Kingdom of Sicily to the court of Peter III of Aragon, who had married Constance, the daughter and heir of Manfred. Manfred's former chancellor, John of Procida, had arranged contact between Michael, Peter and the refugees at his court, and conspirators on the island of Sicily itself. Peter began to assemble a fleet at Barcelona, ostensibly for another Crusade to Tunis. In fact, the master-plan of John of Procida was to place Peter on the throne of Sicily, his Hohenstaufen inheritance. The result was the uprising known as the Sicilian Vespers, which was initiated in Palermo on 29 March 1282. It rapidly grew into a general massacre of the French in Sicily. A few officials notable for their good conduct were spared; and the city of Messina still held for Charles. But through the diplomatic errors of Charles' Vicar, Herbert of Orléans, Messina, too, revolted on 28 April 1282. Herbert retreated to the castle of Mategriffon, but was forced to abandon the Crusading fleet, which was burnt.

The news surprised Peter of Aragon, who had expected to intervene only after Charles had left for Constantinople. But the conspirators, aided by the Emperor Michael (who wished to see Charles balked in his expedition), had set the revolt in motion early. Peter did not immediately intervene; he sailed with the fleet to Tunis, where he discovered that the would-be convert on whose behalf the crusade had ostensibly been undertaken had been caught and executed. While he bided his time, the Sicilians made an appeal to Pope Martin to take the Communes of their cities under his protection. But Martin was far too deeply committed to Charles and French interests to heed them; instead, he excommunicated the rebels, the Emperor Michael, and the Ghibellines in north Italy. Charles gathered his forces in Calabria and made a landing near Messina and began a siege. Several attempts to assault the city were unsuccessful. Rejected by the Pope, the Sicilians now appealed to King Peter and Queen Constance; he duly accepted, and landed at Trapani on 30 August 1282. He was proclaimed King in Palermo on 4 September; as the Archibishopric of Palermo was vacant, he could not immediately be crowned. In the face of the Aragonese landing, Charles was compelled to withdraw across the Straits of Messina into Calabria in September; but the Aragonese moved swiftly enough to destroy part of his army and most of his baggage. The Angevin house was forever ousted from Sicily.
