When did U.S. troops leave Iraq?

U.S. troops officially completed their withdrawal from Iraq in 2011. This withdrawal marked the formal end of the Iraq War, which began in 2003. The departure of the last combat troops in December 2011 was a fulfillment of the Status of Forces Agreement signed in 2008 between the U.S. and Iraqi governments.

• In 2008, the Status of Forces Agreement was signed, setting the timeline for withdrawal, but troops remained.
• In 2014, U.S. troops returned to Iraq in an advisory and training capacity to assist Iraqi forces in combating the rise of ISIS, not as a withdrawal.
• In 2016, U.S. military presence continued in support of counter-ISIS operations.
