The Arab Ba'ath Party merged with Akram al-Hawrani's Arab Socialist Party to establish the Arab Socialist Ba'ath Party in 1952; Aflaq was elected the party's leader in 1954. During the mid-to-late 1950s the party began developing relations with Gamal Abdel Nasser, the President of Egypt, which eventually led to the establishment of the United Arab Republic (UAR). Nasser forced Aflaq to dissolve the party, which he did, but without consulting with party members. Shortly after the UAR's dissolution, Aflaq was reelected as Secretary General of the National Command of the Ba'ath Party. Following the 8th of March Revolution, Aflaq's position within the party was weakened to such an extent that he was forced to resign as the party's leader in 1965. Aflaq was ousted during the 1966 Syrian coup d'état, which led to a schism within the Ba'ath Party. He escaped to Lebanon, but later went to Iraq. In 1968 Aflaq was elected Secretary General of the Iraqi-led Ba'ath Party; during his tenure he held no "de facto" power. He held the post until his death on 23 June 1989.
