Antioch and its port, Seleucia Pieria, were severely damaged by the great earthquake of 526. Seleucia Pieria, which was already fighting a losing battle against continual silting, never recovered. Justinian I renamed Antioch Theopolis ("City of God") and restored many of its public buildings, but the destructive work was completed by the Persian king, Khosrau I, twelve years later, who deported the population to a newly built city in Persian Mesopotamia, Weh Antiok Khosrow. Antioch lost as many as 300,000 people. Justinian I made an effort to revive it, and Procopius describes his repairing of the walls; but its glory was past.
