He was born into a prominent Kurdish feudal family based in Chihriq castle located near the Baranduz river in the Urmia region of northwestern Iran.

In 1919, Mukarram ul-Molk (fa), the governor of Azerbaijan devised a plot to kill Simko by sending him a present with a bomb hidden in it.

[17] In the battle of sari Taj in 1922, Simko's forces could not resist the Iranian Army's onslaught in the region of Salmas and were finally defeated and the castle of Chari was occupied.

[19] In the words of Kurdologist and Iranologist Garnik Asatrian:[21] In the recent period of Kurdish history, a crucial point is defining the nature of the rebellions from the end of the 19th and up to the 20th century―from Sheikh Ubaydullah’s revolt to Simko’s (Simitko) mutiny.

The chimerical idea of this imagined unity has become further the fundament of Kurdish identity-making, resulting in the creation of fantastic ethnic and cultural prehistory, perversion of historical facts, falsification of linguistic data, etc.

On the other hand, Reza Shah's military victory over Simko and Turkic tribal leaders initiated a repressive era toward non-Persian minorities.

While some Marxist political activists (see Nābdel 1977) and ethno-nationalist intellectuals of different Iranian groups (Ghassemlou 1965; Hosseinbor 1984; Asgharzadeh 2007) have introduced this confrontation as a result of Reza Shah’s ethnocentric policies, no valid documents have been presented to prove this argument.

Recent documentary studies (Borzū’ī 1999; Zand-Moqaddam 1992; Jalālī 2001) convincingly show that Reza Shah’s confrontation with Baluch Dust Mohammad Khan, Kurdish Simko and Arab Sheikh Khaz‘al have merely been the manifestation of state-tribe antagonism and nothing else.
