Saddam Hussein is responsible for approximately 230,000 deaths or 'disappearances' from his civilian population (actual figures are not available, sources differ between 160,000 and 300,000). Military casualties are not considered, although they may be as high as 600,000 between the Iran-Iraq war and both Gulf Wars.
His rule (estimated from the date he gained executive power as "acting deputy chairman of the Revolutionary Command Council" - 17/7/1968 - to the date of the first American military action in Iraq - 3/20/2003) was 12,664 days.
