Mortezā Moṭahharī (Persian: مرتضی مطهری, b. 1338/1920 - d. 1399/1979) was a prominent shi'a jurist, philosopher, theologian, thinker, and writer of the twentieth century. He was a student of Allamah Tabataba'i and Imam Khomeini and was considered to be one of the most influential contemporary Iranian clerics in expounding upon Islamic teachings, in keeping pace with the need of the time. Before the Islamic Revolution, Motahhari's intellectual struggle against the Marxist movement in Iran played a stellar role in turning away the youth from its ideology. He was one of the founders of Husayniyya-yi Irshad, a significant center for propagating Islamic teachings before the revolution. Elucidating Islamic beliefs and acting according to the need of the time were the characteristics of Motahhari's intellectual activities. Motahhari presented Islamic concepts that were earlier dealt with in a complicated manner in a simple and easy manner in his own personal style. His books on different topics have been repeatedly published in Persian and other languages. Motahhari is considered an influential person and an intellectual leader of the Islamic revolution of Iran.
