Abd al-Karim Qasim
On 14 July 1958, a group that identified as the "Free Officers", a secret military group led by General Abd al-Karim Qasim, overthrew the monarchy. This group was markedly Pan-Arab in character, with the exception of Abd al-Karim Qasim, who was an Iraqi Nationalist, which would later hurt his relations with his colleagues. King Faisal II, the Regent and Crown Prince Abd al-Ilah, and Nuri al-Said were all killed.
