Arab Federation

Confederal constitutional diarchy (two Hashemite monarchies) · 14 February – 2 August 1958; on map 1958–1959

The Arab Federation was the Hashemite counter-move to Nasserism in the "Arab Cold War." Pan-Arab unity schemes involving the Hashemite houses of Baghdad and Amman went back to the Fertile Crescent Plan and were attempted in 1946–47 and again in 1951–52, when King Abdullah's assassination briefly raised the idea of a joint throne for Faisal II.

Origins & rise

The Arab Federation was the Hashemite counter-move to Nasserism in the "Arab Cold War." Pan-Arab unity schemes involving the Hashemite houses of Baghdad and Amman went back to the Fertile Crescent Plan and were attempted in 1946–47 and again in 1951–52, when King Abdullah's assassination briefly raised the idea of a joint throne for Faisal II. Nothing came of these efforts — Iraqis saw Jordan as a resource-poor liability, and Jordan's Palestinian majority and moderation on Israel were suspect. The catalyst for union came on 1 February 1958, when Egypt and Syria merged into the United Arab Republic, with Nasser openly inviting other Arab states to join — an existential threat to the two conservative, Western-aligned Hashemite kingdoms bordering Syria. On 14 February 1958, King Faisal II of Iraq and his cousin King Hussein of Jordan proclaimed the Hashemite Arab Federation in Amman, hoping Kuwait would join as a third member.

History & key rulers

Despite its name, the union was de facto a confederation: foreign policy and defense were unified, and the flag of the 1916 Arab Revolt became the federal flag, but domestic affairs remained national. Iraq's veteran strongman Nuri al-Said resigned the Iraqi premiership to become Premier of the Arab Union. The federation survived barely six months. In early July 1958, Iraqi units of the 3rd Division — including brigades under Brigadier Abd al-Karim Qasim and Colonel Abdul Salam Arif, both secretly Free Officers — were ordered to transit Baghdad en route to Jordan, where tensions with the UAR over the Lebanon crisis were rising. Seizing the pretext, the Free Officers struck in the early hours of 14 July 1958: Arif's troops seized Baghdad's broadcasting station, and detachments killed King Faisal II, Crown Prince Abd al-Ilah and most of the royal family at al-Rihab Palace; Nuri al-Said was caught disguised in women's dress the next day and shot. The Jordanian prime minister Ibrahim Hashem, visiting Baghdad, was also killed. The new Iraqi Republic formally dissolved the federation on 2 August 1958.

Government, religion & culture

The federation was a diarchy of two constitutional monarchies — Faisal II as senior monarch and federal head, Hussein as his cousin-partner — both Sunni Hashemites claiming descent from the Prophet. Their combined realm joined Iraq's oil, larger army and Shia-majority, Kurdish-minority society to Jordan's desert kingdom and its East-and-West-Bank Palestinian population. The union was widely seen inside Iraq as a pro-Western contrivance: Nuri's Baghdad Pact membership (1955) and British patronage had already made the Hashemites appear, to nationalists, as agents of imperialism.

Peak & territory

At its sole moment of existence the federation covered ~533,000 km² — the whole of Iraq plus Jordan including the then-annexed West Bank — from the Gulf to the Jordan River.

Decline & legacy

The 14 July Revolution destroyed both the Iraqi Hashemites and the federation, ended the Baghdad Pact (Iraq withdrew in 1959), triggered Western intervention in Jordan and Lebanon (British paratroops to Amman, US Marines to Beirut), and opened Iraq's long cycle of coups and Ba'athist rule. Ironically, relations between republican Iraq and Jordan later warmed, and by the 1980s Iraq had become Jordan's largest trading partner — an economic echo of the union that 1958 had extinguished.
