After the 2003 invasion of Iraq was completed and the regime of Saddam Hussein was toppled in May 2003, an Iraqi insurgency began that would last until the United States left in 2011. The 2003–2006 phase of the Iraqi insurgency lasted until early 2006, when it escalated from an insurgency to a Sunni-Shia civil war, which became the most violent phase of the Iraq War.
