Historical Trajectory
Phase I: Rise
The Arab Federation was formed on 14 February 1958 when King Faisal II of Iraq and his cousin King Hussein of Jordan united their two Hashemite kingdoms. The union was a direct political response to the formation of the United Arab Republic, the merger of Egypt and Syria announced weeks earlier. Despite its federal name, the entity functioned as a confederation rather than a fully integrated federal state.
Phase II: Zenith
At its brief peak, the federation combined the territories of Iraq and Jordan, encompassing roughly 533,000 km². Both kingdoms shared Hashemite dynastic ties and coordinated their foreign and defense policies in response to pan-Arab nationalist pressures in the region. The federation represented an attempt by two monarchies to present a unified front against the rising tide of Arab republicanism centered in Cairo and Damascus.
Phase III: Decline
The federation collapsed after only six months. On 14 July 1958, a military coup led by General Abd al-Karim Qasim overthrew the Iraqi monarchy, killing King Faisal II. With Iraq now under a republican revolutionary government hostile to the Hashemite union, the federation had no viable foundation. The new Iraqi government formally dissolved the Arab Federation on 2 August 1958, ending the union entirely.
