513 CE
Revolt of Vitalian: Byzantine general Vitalian revolts against Emperor Anastasius I, and conquers a large part of the Diocese of Thrace. He gains the support of the local people, and assembles an army of 50,000–60,000 men. Vitalian defeats the Byzantines at Acris (Bulgaria), on the Black Sea coast. He attacks their fortified Laager in darkness, and in a crushing defeat kills a large part of the imperial army. Vigor becomes bishop of Bayeux. He opposes paganism and founds a monastery later known as Saint-Vigor-le-Grand (Normandy).
