This study treates the last phase of the Hashimite monarchy In Iraq, where from 1941 until the 1958 revolution, Nuri as-Sa´id Pasha either headed or controlled most government coalitions. After World War II he tried to make a long term agreement with Great Britain by means of a new Anglo-Iraqi Treaty but so vehement were public demonstrations against it that the treaty was never ratified. The Arab defeat in Palestine war of 1948 had serious political and economic repercussions in Iraq. The defeat gave the regime the opportunity to impose martial law on the country. Nuri as-Sa´id continued his traditional pro-British policy and, in 1955, aligned Iraq with the Western defence system through the Baghdad Pact, extending British military privileges in the country. Failures in domestic affairs were matched by foreign policy failures. The new alliance with the West achieved through relentless domestic suppression only served to intensify the desire for independence and the nationalist sentiments. The opposition succeeded in bringing the regime down in 1958.
