After the war, al-Bazzaz was chosen as the dean of the Baghdad Law College. In 1956 he was forced out by the government for protesting against the invasion of Egypt by France, Britain and Israel. He signed a petition that was very critical of the Iraqi government's stand during the Suez crisis under the premiership of Nuri as-Said, a staunch opponent of Egyptian president Gamal Abdel Nasser. Al-Bazzaz returned to the Baghdad Law College as the dean after the revolution in 1958. Al-Bazzaz's interest in the pan-Arab movement again put him in disagreement with the new government of Abd al-Karim Qasim (1958–1963), an Iraqi nationalist aligned with communist forces. In 1959 Colonel ‘Abd al-Wahhab al-Shawwaf, who was the Commander of the Mosul Garrison, instigated a rebellion. After four days of fighting, he was killed and the uprising was crushed. Following the collapse of the Shawwaf uprising, al-Bazzaz was arrested and tortured. After his release, al-Bazzaz went to Egypt, where he became the dean of the Institute of Arab Studies at the Arab League.
