The Iraq War began in 2003 and involved a two-phase conflict comprising an initial invasion of Iraq led by U.S. and UK forces and a longer, eight-year phase of occupation and fighting with insurgents.

The Iraqi conflict (2003–present) that started with the 2003 to 2011 Iraq War has seen several phases of insurgency and open conflict:

• Iraqi Civil War (2006–2008), civil war mainly between sectarian militant groups and Iraqi forces and their respective allies
• Iraqi insurgency (2011–2013), the surge in violence involving the Islamic State in Iraq and the Levant (ISIL) that occurred immediately following the end of the 2003 to 2011 Iraq War
• War in Iraq (2013–2017), conflict with ISIL that began when the initial two-year-long insurgency escalated in December 2013
• ISIL insurgency in Iraq (2017–present), low-level ISIL insurgency following territorial defeat in Iraq in 2017
