Abstract
The late 1950s was a turbulent period in the history of Arab nationalism. It saw the birth and demise of unity states (the United Arab Republic and the Arab Union), civil war, revolution and Western intervention. Despite its short five-month lifespan, the Iraqi-Jordanian Hashemite Arab Union contributed to the intensification of the traditional Egyptian-Iraqi rivalry, the overthrow of the Iraqi monarchy in 1958 and the American intervention in Lebanon the same year. It was the result of Arab nationalism, lingering British imperial dreams, the East-West conflict, economic considerations and an inter-Arab cold war. The Arab Union had obvious advantages over the United Arab Republic. Two such advantages were the greater number of cabinet posts granted to Jordan by the Arab Union than were granted to Syria by the United Arab Republic, and the fact that Amman retained its status as capital (one of two union capitals), whereas Damascus was downgraded to the status of provincial capital. These advantages, however, failed to prevent the premature demise of the union, which was caused by a combination of negative domestic and regional perceptions, economic constraint and military commitments.
