After the Andistani Shahilk attempted to stamp out an increase in criminal enterprises with force, the people of Andistan responded with violence culminating in the Andistani Riots. The Kanodite Emperor, Mazyar I, concerned that the riots would spiral out of control, sent in an imperial military force to put down any dissenters. Thousands of civilians died in the harsh crackdown that followed before order was restored to the city.
