Beyond the Arab Cold War brings the Yemen Civil War, 1962-68, to the forefront of modern Middle East History. During the 1960s, in the wake of a coup against Imam Muhammad al-Badr and the formation of the Yemen Arab Republic (YAR), Yemen was transformed into an arena of global conflict. Believing al-Badr to be dead, Egypt, the Soviet Union, and most countries recognized the YAR. But when al-Badr unexpectedly turned up alive, Saudi Arabia and Britain offered support to the deposed Imam, drawing Yemen into an internationally-sponsored civil war. Throughout six years of major conflict, Yemen sat at the crossroads of regional and international conflict as dozens of countries, international organizations, and individuals intervened in the local South Arabian civil war.

Yemen was a showcase for a new era of UN and Red Cross peacekeeping, clandestine activity, Egyptian counterinsurgency, and one of the first largescale uses of poison gas since WWI. Events in Yemen were not dominated by a single power, nor were they sole products of US-Soviet or Saudi-Egyptian Arab Cold War rivalry. Britain, Canada, Israel, the UN, the US, and the USSR joined Egypt and Saudi Arabia in assuming varying roles in fighting, mediating, and supplying the belligerent forces. Despite Cold War tensions, Americans and Soviets appeared on the same side of the Yemeni conflict and acted mutually to confine Egyptian President Gamal Abdel Nasser to the borders of South Arabia. The end of the Yemen Civil War marked the end of both Nasser's Arab Nationalist colonial expansion and the British Empire in the Middle East, two of the most dominant regional forces.

This internationalized conflict was a pivotal event in Middle East history, overseeing the formation of a modern Yemeni state, the fall of Egyptian and British regional influence, another Arab-Israeli war, Saudi dominance of the Arabian Peninsula, and shifting power alliances in the Middle East that continue to lie at the core of modern-day conflicts in South Arabia.
