The Coalition Provisional Authority (CPA; Arabic: سلطة الائتلاف المؤقتة) was established as a transitional government following the invasion of Iraq by the United States, United Kingdom and their allies, members of the Multi-National Force – Iraq which was formed to oust the government of Saddam Hussein in 2003. Citing United Nations Security Council Resolution 1483 (2003), and the laws of war, the CPA vested itself with executive, legislative, and judicial authority over the Iraqi government from the period of the CPA's inception on 21 April 2003, until its dissolution on 28 June 2004.
