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. • Anastasius I reduces
taxes in the provinces of
Bithynia and
Asia, to prevent them from joining the rebellion. Vitalian marches to
Constantinople and encamps at the suburb of
Hebdomon (modern
Turkey). • Anastasius I sends an
embassy under the former consul
Patricius to start negotiations. Vitalian declares his aims: restoration of
Chalcedonian Orthodoxy and the settling of the Thracian
foederati. • Vitalian accepts an agreement and returns with his army to
Lower Moesia. After a few inconclusive skirmishes, Anastasius I sends a Byzantine army (80,000 men) under his nephew
Hypatius. • 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.
Persia • King
Kavadh I adopts the doctrine of the
Mazdakites, and breaks the influence of the magnates' (
nobility). • The
Jewish community revolts at
Ctesiphon against Mazdakism, and establishes an independent Jewish kingdom that lasts for seven years.
