Provincial Iraqi Control

The history of Iraq from 2003 to 2011 is characterized by a large United States military deployment on 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 countries.

It was a period of violence and political turmoil with strong foreign influence exerted on Iraqi politics. In April 2003, a military occupation was established and run by the Coalition Provisional Authority (CPA), which later appointed and granted limited powers to an Iraq Interim Governing Council. In June 2004, a caretaker government was established – the Iraqi Interim Government. Following parliamentary elections in January 2005, this administration was replaced in May by the Iraqi Transitional Government. A year later, the Al Maliki I Government took office.

During this period, tens of thousands of private military company personnel—many from abroad—were employed in the protection of infrastructure, facilities and personnel. Efforts toward the reconstruction of Iraq after the damage of the invasion were slowed when coalition and allied Iraqi forces fought a stronger-than-expected militant Iraqi insurgency, leading to difficult living conditions for the population of Iraq throughout the period.
