Theodora demonstrated her importance to the emperor during the Nika Revolt of 532, when Constantinople was nearly destroyed by rioters. Byzantine society was dominated by two rival groups called the Greens and the Blues, distinguished by the colors of horse-racing teams that competed at the Hippodrome, or stadium. Justinian and Theodora favored the Blues, and when he made an appearance in their company at the Hippodrome on January 13, 532, this sparked a riot. Suddenly the Greens attacked the Blues, chanting a favorite cheer from the races: “Nika!" (Conquer!). Constantinople was plunged into five days of bloodshed, fires, and looting, which very nearly destroyed the city and toppled Justinian's government. By January 18, leaders of the Blues and Greens, realizing that Justinian's high taxes were the source of all their troubles, had joined forces against Justinian, and were ready to storm the palace.
Theodora sat by in silence while Justinian's advisors suggested that he try to escape the city. Then she stood and

Addressed the imperial council with one of the most remarkable speeches in history. "It is impossible for a man, once born, not to die," she said, and went on to remind her husband that with the great wealth of the imperial court, they could easily escape. But, she said, she agreed with a saying of the ancient orator Isocrates (eye-SAHK-ruh-teez; 436-338 b. c.) "that the imperial purple makes the best burial sheet"—in other words, that it is better to die a king than to live as a coward. Justinian was moved to action by Theodora's speech, and he sent an army led by his great general Belisarius (c. 505-565) to crush the rioters. The soldiers ruthlessly slaughtered more than thirty thousand people in the Hippodrome.
The Nika Revolt was a critical turning point in Justinian's reign because his response to it (thanks to his wife and his general) helped him gain a firm grip on power. Also in 532, Byzantium signed a peace agreement with an age-old enemy to the east, Persia (modern-day Iran). This gave Justinian the freedom to turn westward and pursue his greatest ambition: the reunification of the Roman Empire.
