evidence: Formerly part of the Ottoman Empire, Iraq was occupied by the United Kingdom during World War I and was declared a League of Nations mandate under UK administration in 1920. Iraq attained its independence as a kingdom in 1932. It was proclaimed a republic in 1958 after a coup overthrew the monarchy, but in actuality, a series of strongmen ruled the country until 2003. The last was SADDAM Hussein, from 1979 to 2003. Territorial disputes with Iran led to an inconclusive and costly war from 1980 to 1988. In 1990, Iraq seized Kuwait but was expelled by US-led UN coalition forces during the two-month-long Gulf War of 1991. After Iraq's expulsion, the UN Security Council (UNSC) required Iraq to scrap all weapons of mass destruction and long-range missiles and to allow UN verification inspections. Continued Iraqi noncompliance with UNSC resolutions led to the Second Gulf War in 2003, when US-led forces ousted the SADDAM regime.
