The Ottoman invasion of Otranto occurred between 1480 and 1481 at the Italian city of Otranto in Apulia, southern Italy. Forces of the Ottoman Empire invaded and laid siege to the city and its citadel. According to a traditional account, more than 800 inhabitants were beheaded after the city was captured. The Martyrs of Otranto are still celebrated in Italy. A year later the Ottoman garrison surrendered the city following a siege by Christian forces and the intervention of papal forces led by the Genoese Paolo Fregoso.
