The 2017 Iraqi–Kurdish conflict, also known as the Kirkuk Crisis, was a conflict in which the Iraqi government retook disputed territories in Iraq which had been held by the Peshmerga since ISIL's Northern Iraq offensive in 2014. The conflict began on 15 October 2017 after tensions arising from the Kurdistan Region independence referendum of 25 September. The tension between the federal Iraqi government and Kurdistan Region escalated into conflict when the Peshmerga ignored repeated warnings to return Kirkuk to Iraqi government forces. Part of the conflict was the Battle of Kirkuk, when Iraqi forces regained control of the city.
