Fuad Chehab
Karami was a part of the Muslim-Leftist faction in Lebanese politics. During the 1950s, he was a political follower of the Pan-Arabism of Egyptian president Gamal Abdel Nasser. He was first appointed Prime Minister by President Camille Chamoun on 19 September 1955. By the following year, however, he had seriously fallen out with Chamoun over the latter's refusal to sever diplomatic relations with the western powers that had attacked Egypt in the 1956 Suez Crisis of 1956. He again opposed Chamoun in the 1958 Lebanon Crisis, a Nasserist uprising with considerable support in the Muslim community which erupted in May 1958 and attempted to topple the government and join Egypt and Syria in the new United Arab Republic. By September, when Chamoun had quelled the uprising with the aid of United States Marines, Karami formed a government of national unity under the new President, Fuad Chehab.
