Arab Union
Tension between the UAR and the Arab Union (Arab Federation) resulted in the fall of as-Said, the Union and the entire Iraqi Hashemite regime. During the summer of 1958, UAR troop movements to the Syrian border instigated the Arab Union to mobilize troops to counter this move. In July 1958, troops led by Abd al-Karim Qasim travelling through Iraq, took a chance to overthrow the King and his government in Baghdad. With the fall and resulting deaths of Saed, King Faisal II and the rest of the Iraqi royal family, both the Hashemite regime fell and with it the short-lived Arab Union.
