On January 1, 532 an insurrection broke out unexpectedly in Byzantium (Istanbul) among the populace, and, contrary to expectation, it proved to be a very serious affair in the history of Byzantine Empire, and ended in great harm to the people and to the senate.

In every city the population has been divided for a long time past into the Blue and the Green factions; but within comparatively recent times it has come about that, for the sake of these names and the seats which the rival factions occupy in watching the games in the Hippodrome, they spend their money and abandon their bodies to the most cruel tortures, and even do not think it unworthy to die a most shameful death. And they fight against their opponents knowing not for what end they imperil themselves, but knowing well that, even if they overcome their enemy the fight, the conclusion of the matter for them will be to be carried off straight away to the prison, and finally, after suffering extreme torture, to be destroyed. So there grows up in them against their fellow men a hostility which has no cause, and at no time does it cease or disappear, for it gives place neither to the ties of marriage nor of relationship nor of friendship, and the case is the same even though those who differ with respect to these colors be brothers or any other kin.

At this time the officers of the city administration in Byzantium were leading away to death some of the rioters. But the members of the two factions conspiring together and declaring a truce with each other, seized the prisoners and then straightway entered the prison and released all those who were in confinement there. Fire was applied to the city as if it had fallen under the hand of an enemy. The emperor and his consort , with a few members of the senate shut themselves up in the palace and remained quietly there. Now the watch-word which the populace passed to one another was Nika [i.e., "Conquer"].

On the fifth day of the insurrection in the late afternoon the Emperor Justinian gave orders to Hypatius and Pompeius, nephews of the late emperor, Anastasius, to go home as quickly as possible, either because he suspected that some plot was being matured by them against his own person, or, it may be, because destiny brought them to this. But they feared that the people would force them to the throne (as in fact fell out), and they said that they would be doing wrong if they should abandon their sovereign when he found himself in such danger. When the Emperor Justinian heard this, he inclined still more to his suspicion, and he bade them quit the palace instantly.

On the following day at sunrise it became known to the people that both men bad quit the palace where they had been staying. So the whole population ran to them, and they declared Hypatius emperor and prepared to lead him to the market place to assume the power. But the wife of Hypatius, Mary, a discreet woman, who had the greatest reputation for prudence, laid hold of her husband and would not let go, but cried out with loud lamentation and with entreaties to all her kinsmen that the people were leading him on the road to death. But since the throng overpowered her, she unwillingly released her husband, and he by no will of his own came to the Forum of Constantine, where they summoned him to the throne.

The emperor and his court were deliberating as to whether it would be better for them if they remained or if they took to flight in the ships. And many opinions were expressed favoring either course. And the Empress Theodora also spoke to the following effect: "My opinion then is that the present time, above all others, is inopportune for flight, even though it bring safety. For one who has been an emperor it is unendurable to be a fugitive. May I never be separated from this purple, and may I not live that day on which those who meet me shall not address me as mistress. If, now, it is your wish to save yourself, O Emperor, there is no difficulty. For we have much money, and there is the sea, here the boats. However consider whether it will not come about after you have been saved that you would gladly exchange that safety for death. For as for myself, I approve a certain ancient saying that royalty is a good burial-shroud.". When the queen had spoken thus, all were filled with boldness, and, turning their thoughts towards resistance, they began to consider how they might be able to defend themselves if any hostile force should come against them. All the hopes of the emperor were centred upon Belisarius and Mundus, of whom the former, Belisarius, had recently returned from the Persian war bringing with him a following which was both powerful and imposing, and in particular he had a great number of spearmen and guards who bad received their training in battles and the perils of warfare.

When Hypatius reached the Hippodrome, he went up immediately to where the emperor is accustomed to take his place and seated himself on the royal throne from which the emperor was always accustomed to view the equestrian and athletic contests. And from the palace Mundus went out through the gate which, from the circling descent, has been given the name of the Snail. Belisarius, with difficulty and not without danger and great exertion, made his way over ground covered by ruins and half-burned buildings, and ascended to the stadium. Concluding that he must go against the populace who had taken their stand in the Hippodrome - a vast multitude crowding each other in great disorder - he drew his sword from its sheath and, commanding the others to do likewise, with a shout be advanced upon them at a run. But the populace, who were standing in a mass and not in order, at the sight of armored soldiers who had a great reputation for bravery and experience in war, and seeing that they struck out with their swords unsparingly, beat a hasty retreat. Mundus straightway made a sally into the Hippodrome through the entrance which they call the Gate of Death. Then indeed from both sides the partisans of Hypatius were assailed with might and main and destroyed. There perished among the populace on that day more than thirty thousand. The soldiers killed both Hypatius and Pompeius on the following day and threw bodies into the sea. This was the end of the insurrection in Byzantium.
