1924 Kohat riots
The 1924 Kohat riots were major anti-Hindu riots that occurred in Kohat in North-West Frontier Province, British India in 1924. In three days (9–11 September) of riots, over 155[1] Hindus and Sikhs were killed. The entire population of Hindus and Sikhs living there had to flee for their lives. Gandhi undertook a 21 day fast for Hindu-Muslim unity in October 1924.
The riots were caused in response to the publication of a scurrilous book on Mohammed (S.A.W) named 'Ranglila Rasool'.[2]
