On 1 February 1958, Syrian President Shukri al-Quwatli and Egypt's Nasser announced the merging of Egypt and Syria, creating the United Arab Republic, and all Syrian political parties, as well as the communists therein, ceased overt activities. Meanwhile, a group of Syrian Ba'athist officers, alarmed by the party's poor position and the increasing fragility of the union, decided to form a secret Military Committee; its initial members were Lieutenant-Colonel Muhammad Umran, Major Salah Jadid and Captain Hafez al-Assad. Syria seceded from the union with Egypt on 28 September 1961, after a coup.
