The 1935 Yazidi revolt took place in Iraq in October 1935. The Iraqi government, under Yasin al-Hashimi, crushed a revolt by the Kurdish-speaking Yazidi of Jabal Sinjar against the imposition of conscription. The Iraqi army, led by Bakr Sidqi, reportedly killed over 200 Yazidi and imposed martial law throughout the region. Parallel revolts opposing conscription also broke out that year in the northern (Kurdish populated) and mid-Euphrates (majorly Shia populated) regions of Iraq.
The Yazidis of Jabal Sinjar constituted the majority of Iraqi Yazidi population - the third largest non-Muslim minority within the kingdom, and the largest heterodox Kurdish-speaking group in the province of Mosul. In 1939, the region of Jabal Sinjar was once again put under military control, together with the Shekhan District.
