Serving the Byzantine Emperor Justinian during the 6th century A.D., Belisarius defeated a superior Persian force that threatened to extinguish Constantinople; his small army next drove the Vandals out of the ancient Roman provinces of North Africa and forced the Visigoths to retreat from Italy, returning Rome to the Emperor for the final time. His ability to achieve victory against overwhelming odds and his fairness to both his own troops and those of his enemies became legendary. Despite his successes, Justinian recalled Belisarius and, swayed by jealous advisers, accused the general of conspiring to overthrow him. Although innocent, he was publicly humiliated and stripped of his rank. But when a massive army of barbarians moved against Constantinople and the citizenry panicked in fear, they turned to their only true hero, Belisarius. The forsaken general donned his armor, called out his trusted veterans, and repulsed the barbarian horde. But instead of showing gratitude, Justinian banished him from the city.
