1935–1936 Iraqi Shia revolts

The 1935 Rumaytha and Diwaniyya revolt or the 1935–1936 Iraqi Shia revolts consisted of a series of Shia tribal uprisings in the mid-Euphrates region against the Sunni dominated authority of the Kingdom of Iraq. In each revolt, the response of the Iraqi government was to use military force to crush the rebellions with little mercy.
