The Iraqi conflict is an armed conflict that began with the 2003 invasion of Iraq by a United States-led coalition that toppled the government of Saddam Hussein. The conflict continued as an insurgency emerged to oppose the occupying forces and the post-invasion Iraqi government. The United States officially withdrew from the country in 2011 but became reinvolved in 2014 at the head of a new coalition. The main phase of the conflict ended following the defeat of the Islamic State of Iraq and the Levant in the country in 2017 but a low-level ISIL insurgency is ongoing in the rural north parts of the country.
