Iranian legal scholar from Tabriz. Studied in Qom with Abd al-Karim Haeri Yazdi (d. 1937), founder of the modern seminary there, and went to Najaf for higher studies in law with Muhammad Husayn Naini (d. 1936), Abu al-Hasan Isfahani (d. 1946), and Diya al-Din Iraqi (d. 1942). Returned to Tabriz to teach until 1949, and then went back to Qom to teach fiqh. Said to have interceded with the shah in 1963 to spare the life of Ayatollah Ruhollah Khomeini (d. 1989). In 1970 the shah sought to influence Shariat Madari's elevation to the position of marja al-taqlid. In the early 1970s Shariat Madari established in Qom the Dar al-Tabligh-i Islami, an institution of Islamic education and missionizing. He advocated constitutional monarchy and sponsored the Muslim People's Party as a counter to the Khomeini-influenced Islamic Republican Party. He opposed Khomeini's doctrine of vilayat i-faqih and was accused of treason in an assassination plot against Khomeini in April 1982; he was “defrocked” by the regime and spent his last years under house arrest in Qom and Tehran.
