The Ba'ath Party is a political party that originated in Syria and later spread to other Arab countries, including Iraq. The party advocates for Arab nationalism, socialism, and pan-Arab unity. It was founded in the 1940s by Michel Aflaq and Salah al-Din al-Bitar. The Ba'ath Party came to power in Syria in 1963 and in Iraq in 1968. The party has been associated with authoritarian rule and human rights abuses in both countries.
