The Iraqi–Kurdish conflict consists of a series of wars, rebellions and disputes by the Kurds against the central authority of Iraq starting in the 20th century shortly after the defeat of the Ottoman Empire in World War I. Some put the marking point of the conflict beginning to the attempt by Mahmud Barzanji to establish an independent Kingdom of Kurdistan, while others relate to the conflict as only the post-1961 insurrection by the Barzanis. Since the US-led invasion of Iraq and the subsequent adoption of federalism and the recognition of the Kurdistan Region (KRI) as a federal entity in the new Iraqi constitution, the number and scope of armed clashes between the central government of Iraq and the Kurds have significantly decreased. In spite of that, however, there are still outstanding issues that continue to cause strife such as the disputed territories of northern Iraq and rights to export oil and gas, leading to occasional disputes and armed clashes. In September 2023, following a series of punitive measures by the central government in Iraq against KRI, Masrour Barzani sent a letter to the President of the United States expressing concerns about a possible collapse of the Kurdistan Region, and calling for the United States to intervene.

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.
