أكرم الحوراني
The party was founded by the merger of the Arab Baʽath Movement, led by ʿAflaq and al-Bitar, and the Arab Baʽath, led by al-ʾArsūzī, on 7 April 1947 as the Arab Baʿath Party. The party quickly established branches in other Arab countries, although it would only hold power in Iraq and Syria. The Arab Baʿath Party merged with the Arab Socialist Movement, led by Akram al-Hawrani, in 1952 to form the Arab Socialist Baʿath Party. The newly formed party was a relative success, and became the second-largest party in the Syrian parliament in the 1954 election. This, coupled with the increasing strength of the Syrian Communist Party, led to the establishment of the United Arab Republic (UAR), a union of Egypt and Syria. The union would prove unsuccessful, and a Syrian coup in 1961 dissolved it.
