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. The Arab–Israeli conflict Karami served four more times as prime minister throughout the 1960s. During this time, he championed the Palestinian cause, and is believed to have argued for Lebanon to play a more active role against Israel in the Six-Day War of June 1967, a position which was unpopular with many Christians. Increasing clashes between the Lebanese army and the Palestine Liberation Organization forced his resignation in April 1970, but he returned to office in 1975 after an accord had been signed between Lebanon and the PLO. In August that year, however, Suleiman Frangieh, an enemy of Karami, was elected president. Karami resigned and was succeeded by Saeb Salam. Civil war The Civil war erupted in Lebanon in April 1975. Multiple factions were involved and the political and military situation was extremely complex, but broadly speaking, the civil war was fought mainly between right-wing, mainly Christian militias (the most prominent of which was the Phalange), and leftist, mainly Muslim militias and their Palestinian allies. Desperate to stabilize the situation, Frangieh dismissed Prime Minister Rashid al-Solh and called on his old adversary Karami to form a government on 1 July. He retreated somewhat from his previous strong support for the Palestinians and supported the Syrian military intervention of June 1976. Despite Karami's political connections and many years of experience, he was unable to end the war, however, and on 8 December 1976 he resigned. Elias Sarkis, who had succeeded Frangieh as president in September 1976, appointed Selim Hoss as the new Prime Minister. Karami had his militia in Tripoli. He was reconciled to his old enemy, Suleiman Frangieh, in the late 1970s, after Frangieh had fallen out with the Phalangist militia leader, Bachir Gemayel. Together with Frangieh and Walid Jumblatt, Karami founded the National Salvation Front, pro-Syrian coalition of Sunni Muslim, Druze, and some Christians, mainly in the north of Lebanon in July 1983. The National Salvation Front stood in opposition to the presidency of Amine Gemayel and the pact between Lebanon and Israel that was financially supported by the US.
