United States occupation of Iraq was the period following the 2003 invasion of Iraq during which forces led by the United States and allied partners administered, reconstructed, and fought within Iraq. The occupation encompassed the overthrow of the Ba'athist regime, the establishment of the Coalition Provisional Authority, an extended counterinsurgency campaign against groups such as Al-Qaeda in Iraq, and a phased transfer of authority culminating in formal troop withdrawals under the 2008 SOFA. The occupation reshaped regional alignments involving Iran, Turkey, Syria, Saudi Arabia, and international institutions including the United Nations and the NATO partnership.

Background and lead-up to the occupation

Plans and justifications for intervention drew on precedents and actors including the George W. Bush administration, advisors from Defense Policy Board, and intelligence communities such as the Central Intelligence Agency and the MI6. Public rationales cited alleged links between Saddam Hussein's WMD programs and networks like Al-Qaeda, while legal foundations invoked United Nations Security Council Resolution 1441 and prior Gulf War resolutions. Debates involved scholars from Johns Hopkins University, commentators in The New York Times, and legislators in the United States Congress, and prompted diplomatic tensions with France, Germany, and Russia.

Invasion and initial military operations (2003)

The invasion combined forces from the United States Department of Defense, United Kingdom Ministry of Defence, Australia, and Poland in a campaign featuring the Baghdad offensive and battles such as the Battle of Nasiriyah, Fallujah, and seizures of facilities like the Green Zone. Operations relied on units from the Iraqi Freedom task forces, technology from F-117 Nighthawk and AH-64 Apache platforms, and logistics routed through Kuwait and Qatar. The overthrow of Saddam Hussein accelerated collapse of Iraqi Armed Forces structures and produced contested control of infrastructure including Mosul and Basra.

Coalition provisional authority and governance

After hostilities, the Coalition Provisional Authority under Paul Bremer issued orders such as CPA Order 1 and CPA Order 2 that dissolved the Iraqi Army and restructured institutions, while the United Nations Assistance Mission for Iraq and organizations like the World Bank and International Monetary Fund engaged on reconstruction plans. Transitional bodies included the Iraqi Governing Council and later the Iraqi Interim Government, with constitutional processes culminating in the 2005 Iraqi Constitution and elections organized by the Independent Electoral Commission of Iraq. Controversies involved de-Ba'athification, detainee policies at Camp Bucca and Abu Ghraib prison, and disputes with regional actors such as Iran and Turkey over Kurdish autonomy in Iraqi Kurdistan.

Insurgency, sectarian conflict, and security operations

Post-invasion insecurity saw the rise of insurgent groups including Jaysh al-Mahdi, Al-Qaeda in Iraq, and later the ISIL precursor networks, triggering operations like Operation Phantom Fury and multinational campaigns led by Multi-National Force – Iraq. Sectarian violence between Shia Islam militias and Sunni Islam insurgents escalated after the 2005 Iraqi parliamentary election, producing episodes such as the 2006–2007 Iraqi civil war and mass displacement affecting cities including Baghdad, Mosul, and Samarra. US strategy evolved through doctrine such as the 2007 surge overseen by commanders like General David Petraeus, combined with provincial reconstruction teams and cooperation with Iraqi Police and Iraqi Special Operations Forces.

Reconstruction, economic policy, and public services

Reconstruction efforts involved agencies and contractors including the United States Agency for International Development, KBR, and multinational firms, funded in part by supplemental appropriations from the United States Congress and executed alongside initiatives from the United Nations Development Programme. Programs targeted oil infrastructure managed by the Iraqi National Oil Company, electricity networks in Basra and Baghdad, water projects, and health facilities addressing crises such as the humanitarian aftermath. Corruption allegations, the role of Coalition Provisional Authority orders, and disputes over Oil-for-Food Programme legacies complicated recovery and affected employment, public services, and private investment.

Withdrawal, troop reductions, and handover to Iraqi authorities

Political agreements including the 2008 SOFA and diplomatic negotiations in Baghdad and Washington, D.C. led to phased US troop reductions and transfer of sovereignty to the Iraqi Government in ceremonies attended by officials from the United States Department of State, the Iraqi Prime Minister and coalition partners. Major combat units withdrew by 2011, though databases record subsequent deployments, training missions, and air operations in response to the Iraq insurgency (2011–2013) and the rise of ISIL, prompting renewed multinational action under coalitions including Operation Inherent Resolve.

Impact and legacy: political, social, and legal consequences

The occupation influenced regional geopolitics involving Iran–United States relations, Syrian Civil War dynamics, and Turkey–Iraq relations, while domestic effects included debates in the United States Congress, legal scrutiny in courts over detainee treatment, and investigations by media like The Washington Post and The New York Times. Social consequences encompassed refugee flows to Jordan and Syria, sectarian demographic shifts in Baghdad and Mosul, and public health research by institutions such as Johns Hopkins Bloomberg School of Public Health documenting mortality and infrastructure impacts. Legally, the occupation prompted discussion of instruments including the Geneva Conventions and influenced scholarship at universities like Harvard Law School and Yale Law School on sovereignty, occupation law, and transitional justice.
