Communal riots occurred in Bihar from 24 October to 11 November 1946, in which Hindu mobs targeted Muslim families. The riots were triggered by the Great Calcutta Killings, as well as the Noakhali riots earlier that year. Estimates of the number of casualties vary from 2000 to 30,000. Mahatma Gandhi declared that he would fast unto death if the riots did not stop. The riots were part of a sequence of communal violence that culminated in the partition of India.
