Faisal II of Iraq
The Federation was formed on 14 February 1958, when King Faisal II of Iraq and his cousin, King Hussein of Jordan, sought to unite their two Hashemite kingdoms, as a response to the formation of the United Arab Republic between Egypt and Syria. The union lasted only six months, being officially dissolved on 2 August 1958, after Faisal was deposed by a military coup on 14 July.
