Flag of the United Arab Republic in the context of Republic of Egypt (1953–1958)

Neo-Ba'athism is a far-left variant of Ba'athism that became the state ideology of Ba'athist Syria, after the Arab Socialist Ba'ath party's Sixth National Congress in October 1963. As a result of the 1966 Syrian coup d'état launched by the neo-Ba'athist military committee led by Salah Jadid and Hafez al-Assad, Ba'ath party's Syrian regional branch was transformed into a militarist organization that became completely independent of the National Command of the original Ba'ath Party.

Neo-Ba'athism has been described as a divergence from Ba'athism proper that had gone beyond its pan-Arabist ideological basis by stressing the precedent of the military and purging the classical Ba'athist leadership of the old guard, including Michel Aflaq and Salah al-Din al-Bitar. The far-left neo-Ba'athist regime in Syria, which was influenced by various Marxist ideological schools, espoused radical leftist doctrines such as revolutionary socialism abandoned pan-Arabism, sought to strengthen ties with the Soviet Union, and came into conflict with Arab nationalists such as Nasserists and the Iraqi Ba'athists, particularly Saddamists, with whom they maintained a bitter rivalry. From their seizure of power in the Syrian Arab Republic as a result of the 1963 Syrian coup d'état, neo-Ba'athist officers purged traditional civilian elites to establish a military dictatorship operating along totalitarian lines.

Since gaining full independence from France in 1946, Syria has used a number of different flags, all featuring the pan-Arab colors of green, black, white, and red. Initially a green, white and black triband charged with three red five-pointed stars, known as the independence flag, was used. In Ba'athist Syria, this was replaced by the flag of the United Arab Republic with red, white and black tribands with either two or three green stars or charged with the national coat of arms. Following the fall of the Assad regime on 8 December 2024, the revolution flag, a modified version of the independence flag, began to be used within the country by the Syrian parliament and the Syrian caretaker government, and at Syrian embassies abroad. On 13 March 2025, an interim constitution made the independence flag the primary flag. However, the final text ultimately retained the revolution flag.
