Ali Hassan al-Majid (November 30, 1941 - January 25, 2010) was a Ba'athist Iraqi Defense Minister, Interior Minister, military commander and chief of the Iraqi Intelligence Service. He was also the governor of annexed Kuwait, during the Persian Gulf War.
A first cousin of the late Iraqi President Saddam Hussein, he became notorious in the 1980s and 1990s for his role in the Iraqi government's campaigns against internal opposition forces, namely the ethnic Kurdish rebels of the north, and the Shia religious dissidents of the south. Repressive measures included deportations and mass killings; al-Majid was dubbed "Chemical Ali" by Iraqis for his use of chemical weapons in attacks against the Kurds.
Al-Majid was captured following the 2003 invasion of Iraq and was charged with war crimes, crimes against humanity and genocide. He was convicted in June 2007 and was sentenced to death for crimes of genocide against the Kurds committed in the al-Anfal campaign of the 1980s. His appeal of the death sentence was rejected on 4 September 2007, and he was sentenced to death for the fourth time on 17 January 2010 and was hanged eight days later, on 25 January 2010.
