Marcian

Marcian was the eastern Roman emperor from 450 to 457, a former soldier who achieved the purple through his marriage to the Augusta Pulcheria, the powerful sister of Theodosius II. Despite his humble origins, Marcian proved one of the most capable emperors of the fifth century, restoring fiscal stability and refusing to continue the payments to Attila the Hun that had drained the eastern treasury under Theodosius II. His refusal to pay tribute was a bold gamble. Attila's defeat at the Catalaunian Fields in 451 and death in 453 removed the Hunnic threat entirely. Marcian convened the Council of Chalcedon in 451, the fourth ecumenical council, which produced the Chalcedonian Definition of Christ's dual nature. He died in 457, leaving no designated successor.
