How did Kurdistan become a quasi-state?

Kurdistan has not officially become a quasi-state, but there are regions within Iraq, Syria, Turkey, and Iran with predominantly Kurdish populations that have varying degrees of autonomy. These regions have been shaped by historical, political, and social factors, including conflicts, agreements with central governments, and the establishment of governing structures. The Kurdistan Regional Government in Iraq, for example, was established following the 1991 Gulf War and has since gained significant autonomy.
