The Patriotic Union of Kurdistan is a political party active in Kurdistan Region and the disputed territories in Iraq. The PUK describes its goals as self-determination, human rights, democracy and peace for the Kurdish people of Kurdistan and Iraq. The PUK is currently under the leadership of Bafel Talabani. The PUK was founded in 1975 by Jalal Talabani, Nawshirwan Mustafa, Fuad Masum, Adel Murad, Ali Askari and Abdul Razaq Feyli. All presidents of Iraq under the 2005 constitution have been from this party.

Kurdistan Region is an autonomous administrative entity within the Republic of Iraq. It comprises four Kurdish-majority divisions of Arab-majority Iraq: the Erbil Governorate, the Sulaymaniyah Governorate, the Duhok Governorate, and Halabja Governorate. The KRI is bordered by Iran to the east, by Turkey to the north, and by Syria to the west. It does not govern all of Iraqi Kurdistan, and lays claim to the disputed territories of northern Iraq; these territories have a predominantly non-Arab population and were subject to the Ba'athist Arabization campaigns throughout the late 20th century. Though the KRI's autonomy was realized in 1992, one year after Iraq's defeat in the Gulf War, these northern territories remain contested between the Kurdistan Regional Government and the Government of Iraq to the present day. In light of the dispute, the KRI's constitution declares the city of Kirkuk as the capital of Iraqi Kurdistan. However, the KRI does not control Kirkuk, and the Kurdistan Region Parliament is based in Erbil. In 2014, when the Syria-based Islamic State began their Northern Iraq offensive and invaded the country, the Iraqi Armed Forces retreated from most of the disputed territories. The KRI's Peshmerga then entered and took control of them for the duration of the War in Iraq (2013–2017). In October 2017, following the defeat of the Islamic State, the Iraqi Armed Forces attacked the Peshmerga and reasserted control over the disputed territories.
