Which country has an autonomous region recognized by the constitution populated entirely by Kurds?

So sad how these good people are being so mistreated first by Saddam, and then by the US.

Kurdistan Region is a SEMI-autonomous administrative entity in the Republic of Iraq. It comprises four Kurdish-majority governorates of Arab-majority Iraq: Erbil Governorate, Sulaymaniyah Governorate, Duhok Governorate, and Halabja Governorate. It is located in northern Iraq, at the country’s borders with Iran, Turkey, and Syria.
