During World War II it was part of the Axis Independent State of Croatia (NDH), where the fascist Ustaše regime committed the Genocide of the Serbs and the Holocaust. At the beginning of May 1941 in several villages south-east of Sanski Most (Kijevo, Tramošnja, Kozica, etc.) the first armed conflict between the Ustaše and insurgent Serbs occurred. The event is known as the Đurđevdan uprising. In August 1941 on the Eastern Orthodox Elijah's holy day, who is the patron saint of Bosnia and Herzegovina, between 2,800 and 5,500 Serbs from Sanski Most and the surrounding area were killed and thrown into pits which have been dug by victims themselves. The State Anti-fascist Council for the National Liberation of Bosnia and Herzegovina (ZAVNOBiH) held its second meeting from 30 June to 2 July 1944 in the town; it declared the equality of Muslims (Bosniaks), Serbs and Croats.
