Zabergan

Zabergan was the chieftain of the Kutrigurs, a Turkic nomadic tribe of the Pontic–Caspian steppe, after Sinnion. His name is Iranian, meaning full moon. Either under pressure from incoming Avars, or in revolt against the Byzantine Empire, in the winter of 558, he led a large Kutrigur army that crossed the frozen Danube. The army was divided into three sections: one raided south far as Thermopylae, while two others the Thracian Chersonesus and the periphery of Constantinople. In March 559 Zabergan attacked Constantinople, and one part of his forces consisted of 7,000 horsemen, but Belisarius defeated him at the Battle of Melantias and he was forced to withdraw.
