1943 Barzani revolt

The 1943–1945 Barzani revolt was a Kurdish nationalistic insurrection in the Kingdom of Iraq, during World War II. The revolt was led by Mustafa Barzani and was later joined by his older brother Ahmed Barzani, the leader of the previous Kurdish revolt in Iraq. The revolt, initiating in 1943, was eventually put down by the Iraqi assault in late 1945, combined with the defection of a number of Kurdish tribes. As a result, the Barzanis retreated with much of their forces into Iranian Kurdistan, joining the local Kurdish elements in establishing the Republic of Mahabad.
