The first five years of President Al-Sallal's rule, from 1962 to 1967, comprised the first chapter in the history of North Yemen. Marked by the revolution that began it, this period witnessed a lengthy civil war between Yemeni republican forces, based in the cities and supported by Egypt, and the royalist supporters of the deposed imam, backed by Saudi Arabia and Jordan. In 1965 Egyptian president Gamal Abdel Nasser met with King Faisal of Saudi Arabia to consider a possible settlement to the civil war. The meeting resulted in an agreement whereby both countries pledged to end their involvement and allow the people of North Yemen to choose their own government. Subsequent peace conferences were ineffectual, however, and fighting flared up again in 1966.
