The
history of Iraq from 2003 to 2011 is a period in Iraqi history characterized by a large American troop deployment in Iraqi territory, beginning with the
U.S.-led invasion of the country in March 2003 which
overthrew the
Ba'ath Party government of
Saddam Hussein and ending with the
departure of US troops from the country in 2011 (though the
Iraq War that commenced in 2003 continued and subsequently intensified during 2013). Troops for the invasion came primarily from the United States, the United Kingdom and Poland, but 29 other nations also provided some troops, and there were varying levels of assistance from
Japan and other allied countries.
