This research revolves around the transformations in the life and thought of radical Islamist Sayyid Qutb of Egypt (1906-1966), a prolific writer, a poet, an educator, a literary critic, and a highly controversial ideologue of contemporary Islamism who was executed by the late-President Nasser regime of Egypt on August 29, 1966. His posthumous impact on radical Islamists was profound on some leaders in Iran and Afghanistan and on al-Qaeda and its leaders, especially the late Dr. Ayman al-Zawahiri and fellow global jihadist Abdallah Azzam and many others, including the late-blind cleric Sheikh Omar Abd al-Rahman who immigrated and died in the United States.
