The Arab Socialist Baʿth Party was a political party founded in Syria by Mishel ʿAflaq, Ṣalāḥ al-Dīn al-Bīṭār, and associates of Zakī al-ʾArsūzī. The party espoused Baʿathism, which is an ideology mixing Arab nationalist, pan-Arab, Arab socialist, and anti-imperialist interests. Baʿthism calls for unification of the Arab world into a single state. Its motto, "Unity, Liberty, Socialism", refers to Arab unity, and freedom from non-Arab control and interference.
