In 1963 the Ba'ath Party seized power, from then on the Ba'ath functioned as the only officially recognized Syrian political party, but factionalism and splintering within the party led to a succession of governments and new constitutions. On 23 February 1966, a bloody coup d'état led by a more left-wing, radical Ba'athist faction headed by Chief of Staff Salah Jadid, overthrew Aflaq and the Salah al-Din al-Bitar's Government. The coup sprung out of factional rivalry between Jadid's "regionalist" (qutri) camp of the Ba'ath Party, which promoted ambitions for a Greater Syria and the more traditionally pan-Arab, in power faction, called the "nationalist" (qawmi) faction.
