Arab Socialist Ba'ath Party – Syria Region

The Arab Socialist Ba'ath Party – Syria Region (Arabic: حزب البعث العربي الاشتراكي – قطر سوريا Ḥizb al-Ba'th al-'Arabī al-Ishtirākī – Quṭr Sūriyā), officially the Syrian Regional Branch (Syria being a "region" of the Arab nation in Ba'ath ideology), is a neo-Ba'athist organisation founded on 7 April 1947 by Michel Aflaq, Salah al-Din al-Bitar and followers of Zaki al-Arsuzi. The party has ruled Syria continuously since the 1963 Syrian coup d'état which brought the Ba'athists to power. It was first the regional branch of the original Ba'ath Party (1947–1966) before it changed its allegiance to the Syrian-dominated Ba'ath movement (1966–present) following the 1966 split within the original Ba'ath Party. Since their ascent to power in 1963, neo-Ba'athist officers proceeded by stamping out the traditional civilian elites to construct a military dictatorship operating in totalitarian lines; wherein all state agencies, party organisations, public institutions, civil entities, media and health infrastructure are tightly dominated by the army establishment and the Mukhabarat (intelligence services).

The 1966 coup d'état by the radical left-wing faction of Salah Jadid and General Hafez al-Assad ousted the Old Guard of Ba'ath leadership consisting of Michel Aflaq and Salah al-Din Bitar; and dissolved the National Command of the united Ba'ath party. The leftist faction of the Syrian Baath advanced a strictly socialist economic programme, pursued closer alliance with the Syrian communists, "progressive" Arab states and the Soviet Bloc and prioritised the spread of socialist revolution in the neighbouring "reactionary" Arab states over pan-Arab unity. The official ideology preached by the Syrian Ba'ath is known as neo-Ba'athism, a school of Ba'athist thought that denounces Aflaq and Bitar and eulogizes Alawite philosopher Zaki al-Arsuzi as the leading theoretician. In another coup in 1970, officially dubbed the "Corrective Movement", Hafez al-Assad would overthrow the Jadid faction and tone down the revolutionary measures. The new regime emphasized building socialism in Syria first and was open to alliances with the neighbouring countries. Since this period, the party has adopted Assadism as its official ideology; promoting a personality cult centred around the Assad dynasty.
