The Simko Shikak revolt refers to an armed Ottoman-backed tribal Kurdish uprising against the Qajar dynasty of Iran from 1918 to 1922, led by Kurdish chieftain Simko Shikak from the Shekak tribe. After Brigadier-General Reza Khan deposed the Qajars in a 1921 coup, he defeated Simko Shikak as well as several prominent rebel commanders such as Kuchik Khan and Colonel Pessian during the Iranian events of 1921. The Shikak rebellion resulted in some 5,000 killed, including many Assyrian civilians, who were massacred by Simko's forces.
