The people of Constantinople developed their own brand of orthodoxy, which was neither that of Rome nor that of Alexandria, and rioted against any emperor who threatened to compromise it. A very strong emperor might have been able to force the peoples of the East to accept a common statement of religious beliefs if he had not had to worry about the opposition of the pope at Rome. Conversely, agreement between Rome and Constantinople could be secured only by losing the religious, which meant in the end the political, allegiance of Egypt and Syria.
These were the strains which made the reign of the great Justinian (527-565) a spectacular failure instead of a world-changing success.

Even Justinian's most successful enterprise, the modernization and codification of Roman law, was in some ways a
