Imam Ayatollah Seyed Ruhollah Musavi Khomeini (May 17, 1900 – June 3, 1989) was a Muslim cleric and Marja, and the political leader of the 1979 Islamic Revolution of Iran which overthrew Mohammad Reza Pahlavi, the last Shah of Iran. Following the Revolution, Imam Khomeini became Grand Leader of Iran — the paramount figure in the political system of the new Islamic Republic — until his demise.
Imam Khomeini was considered a Marja-e taqlid to many Muslims, and in Iran was officially addressed as Imam rather than Grand Ayatollah; his supporters adhere to this convention. Imam Khomeini was also a highly-influential and innovative Islamic political theorist, most noted for his development of the theory of velayat-e faqih, the “guardianship of the jurisconsult.”
In 1929, Imam Khomeini married Batol Saqafi Khomeini, the daughter of a cleric in Tehran. They had seven children, though only five survived infancy, 3 daughters and 2 sons. His sons entered into religious life. The elder son, Mostafa, was murdered in 1977 while in exile with his father in Najaf, Iraq and SAVAK (the Imperial-era secret police) was accused of his death by Imam Khomeini. Ahmad Khomeini, the younger son, died in 1995.
