Мартин IV
Soon after the Vespers itself, the Sicilians turned to Peter of Aragon to deliver them from French dominion. An Aragonese fleet under Peter himself had landed at Collo, now in eastern Algeria, and to those troops the Sicilians sent envoys. Peter was offered the throne of Sicily and accepted. Simon de Brie, who had taken the name Pope Martin IV, had meanwhile refused to help the Sicilian communes and the rebels were excommunicated, as was the Byzantine emperor and the Ghibellines of northern Italy.
