The crushing defeat experienced by Pisa in 1284 in the Battle of Meloria against Genoa had among its consequences the end of the Pisan rule and the beginning of the Genoese influence in Corsica: this was contested initially by the King of Aragon, who in 1296 had received from the Pope the investiture over Sardinia and Corsica. A popular revolution against this and the feudal lords, led by Sambucuccio d'Alando, got the aid of Genoa. After that, the "Cismonte" was ruled as a league of comuni and churches, after the Italian experience. The following 150 years were a period of conflict, when the Genoese rule was contested by Aragon, the local lords, the comuni and the Pope: finally, in 1450 Genoa ceded the administration of the island to its main bank, the Bank of Saint George, which brought peace.
