Ali Shariati Mazinani was an Iranian revolutionary and sociologist who focused on the sociology of religion. He is held as one of the most influential Iranian intellectuals of the 20th century, and has been called the "ideologue of the Islamic Revolution", although his ideas did not end up forming the basis of the Islamic Republic.

The Iranian Revolution, also known as the Islamic Revolution, was a series of events that culminated in the overthrow of the Pahlavi dynasty in 1979. The revolution also led to the replacement of the Imperial State of Iran by the present-day Islamic Republic of Iran, as the monarchical government of Mohammad Reza Pahlavi was superseded by the theocratic government of Ayatollah Ruhollah Khomeini, a religious cleric who had headed one of the rebel factions. The ousting of Pahlavi, the last Shah of Iran, formally marked the end of Iran's historical monarchy.
