In short
In January 532, riots erupted in Constantinople over chariot racing factions and tax grievances, quickly spiraling into a citywide uprising against Byzantine Emperor Justinian I. Over six days, imperial forces crushed the rebellion, killing an estimated 30,000 people in the Hippodrome alone. The massacre effectively eliminated organized opposition to Justinian's reign and enabled his most ambitious projects, including the reconquest of the Western Roman Empire.
How it unfolded.
The five-minute version
What actually happened.
A massacre is an event of killing defenseless human beings or animals. It is generally used to describe a targeted mass killing of civilians by an armed group. It can also be used figuratively to refer to a one-sided exchange between armed groups. The word is a loan of a French term for "butchery" or "carnage". Other terms with overlapping scope include war crime, pogrom, mass killing, mass murder, and extrajudicial killing.
