Qāsim was assassinated in February 1963, when the Ba'ath Party took power under the leadership of General Ahmed Hasan al-Bakr (prime minister) and Colonel Abdul Salam Arif (president). Nine months later `Abd as-Salam Muhammad `Arif led a successful coup against the Ba'ath government. On 13 April 1966, President Abdul Salam Arif died in a helicopter crash and was succeeded by his brother, General Abdul Rahman Arif. Following the Six-Day War of 1967, the Ba'ath Party felt strong enough to retake power (17 July 1968). Ahmad Hasan al-Bakr became president and chairman of the Revolutionary Command Council (RCC).
