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 (Arabic: الفرع القطري السوري), was a Ba'athist organisation founded on 7 April 1947 by Michel Aflaq, Salah al-Din al-Bitar and followers of Zaki al-Arsuzi. The party ruled Syria from the 1963 coup d'état, which brought the Ba'athists to power, until 8 December 2024, when Bashar al-Assad fled Damascus in the face of a rebel offensive during the Syrian civil war. It was formally disbanded in January 2025.

The party was founded on 7 April 1947 as the Arab Ba'ath Party through the merger of the Arab Ba'ath Movement led by Michel ʿAflaq and Salah al-Din al-Bitar and the Arab Ba'ath, led by Zaki al-Arsuzi. The party espoused Ba'athism, an ideology mixing Arab nationalist, pan-Arab, Arab socialist, and anti-imperialist interests. Ba'athism calls for the unification of the Arab world into a single state. It quickly established branches in other Arab countries, although it would only hold power in Syria and in Iraq. Following their ascent to power in 1963, neo-Ba'athist officers proceeded to stamp out the traditional civilian elites in order to construct a military dictatorship operating on totalitarian lines; wherein all state agencies, party organisations, public institutions, civil entities, media and health infrastructure were tightly dominated by the military establishment and the Mukhabarat (intelligence services).

The 1966 coup d'état carried out by the radical left-wing faction of Salah Jadid and Hafez al-Assad ousted the Old Guard of Ba'ath leadership consisting of Aflaq and Bitar; and dissolved the National Command of the united Ba'ath Party. The leftist faction of the Syrian Ba'ath advanced a strictly socialist economic programme, pursued a 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 Arsuzi as its leading theoretician.

In another coup in 1970, officially dubbed the "Corrective Revolution", 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 neighbouring countries. From this period, the party adopted Assadism as its official ideology, promoting a personality cult centred around the Assad dynasty.

Following the fall of the Assad regime on 8 December 2024, on 11 December, the party suspended all activities "until further notice" and transferred its assets to the Syrian caretaker government. On 29 January 2025, the party was formally dissolved by the Syrian caretaker government during the Syrian Revolution Victory Conference.
