In this context, the influence of Nasserism, Pan-Arab and anti-imperial ideologies created fertile ground for the idea of closer ties with Egypt. The appeal of Egyptian President Gamal Abdal Nasser's leadership in the wake of the Suez Crisis created support in Syria for union with Egypt. On 1 February 1958, Syrian President al-Quwatli and Nasser announced the merging of the two states, creating the United Arab Republic. The union was not a success, however. Discontent with Egyptian dominance of the UAR, led elements opposed to the union under Abd al-Karim al-Nahlawi, to seize power on 28 September 1961. Two days later, Syria re-established itself as the Syrian Arab Republic. Frequent coups, military revolts, civil disorders and bloody riots characterized the 1960s. The 8 March 1963 coup, resulted in installation of the National Council of the Revolutionary Command (NCRC), a group of military and civilian officials who assumed control of all executive and legislative authority. The takeover was engineered by members of the Ba'ath Party led by Michel Aflaq and Salah al-Din al-Bitar. The new cabinet was dominated by Ba'ath members; the moderate al-Bitar became premier. He was overthrown early in 1966 by left-wing military dissidents of the party led by General Salah Jadid.
