Justinian considered fleeing, but his wife Theodora convinced him to stay in the city. Justinian had his generals Belisarius and Mundus suppress the revolt on January 18, which they did with much bloodshed by trapping the rebels in the Hippodrome. About thirty thousand rioters were reportedly killed. Justinian also had Hypatius executed and exiled the senators who had supported the riot.
According to the disapproving Tertullian (De spectaculis 9.5), there were originally just two factions, White and Red, sacred to winter and summer respectively. Writing near the beginning of the third century, he wrote that the Reds were dedicated to Mars, the Whites to the Zephyrs, the Greens to Mother Earth or spring, and the Blues to the sky and sea or autumn. Domitian created two new factions, the Purples and Golds which disappeared soon after he died, but by the 3rd century only the Blues and Greens had any importance.
Chariot racing in the Byzantine Empire also included the Roman racing clubs, but by this time only the Blues and Greens were important
Other scholars (and those who venerate Theodora as a saint) instead regard Theodora's achievements for women not as a modern feminist "liberation" to commit abortion or adultery but rather as a truly egalitarian drive to give women the same legal rights as men, such as establishing homes for prostitutes, passing laws prohibiting forced prostitution, granting women more rights in divorce cases, allowing women to own and inherit property, and enacting the death penalty for rape, all of which raised women's status far above that current in the Western portion of the Empire.

Some scholars believe that Theodora was Byzantium's first noted proponent-and, according to Procopius, practitioner-of abortion; she convinced Justinian to change the law that forbade noblemen to marry lower class women (like herself). Theodora also advocated the rights of married women to commit adultery, and the rights of women to be socially serviced, helping to advance protections and delights for them; and was also something of a voice for prostitutes and the downtrodden. She also helped to mitigate the breach in Christian sects that loomed large over her time; she probably had a large part in Justinian's efforts to reconcile the Monophysites to orthodoxy.
On January 13, a tense and angry populace arrived at the Hippodrome for the races. The Hippodrome was next to the palace complex and thus Justinian could watch from the safety of his box in the palace and preside over the races. From the start the crowd had been hurling insults at Justinian. By the end of the day, at race 22, the partisan chants had changed from "Blue" or "Green" to a unified "Nika" (a Greek exhortation meaning to "win", "conquer", or "achieve victory"), and the crowds broke out and began to assault the palace. For the next five days the palace was under virtual siege.
Some of the senators saw this as an opportunity to overthrow Justinian, as they were opposed to his new taxes and his lack of support for the nobility. The rioters, now armed and probably controlled by their allies in the Senate, also demanded that Justinian dismiss the prefect John the Cappadocian, who was responsible for tax collecting, and the quaestor Tribonian, who was responsible for rewriting the legal code. They then declared a new emperor, Hypatius, who was a nephew of former Emperor Anastasius I.
