Purging of non-Islamic influences among academia after the 1979 Islamic Revolution This article is about the Iranian Cultural Revolution, 1980–1983. ( Learn how and when to remove this message ) The Cultural Revolution (1980–1983; : Enqelābe Farhangi) was a period following the Iranian Revolution , when the academia of Iran was purged of Western and non-Islamic influences, (including traditionalist unpolitical Islamic doctrines) to align them with the revolutionary and political Islam . The cultural revolution sometimes involved violence in taking over the university campuses, as higher education in Iran had many secularist and leftist forces who were opposed to Ayatollah Khomeini's Islamic state in Iran. The official name used by the Islamic Republic is "Cultural Revolution". Directed by the Cultural Revolutionary Headquarters and later by the Supreme Cultural Revolution Council, the revolution initially closed universities for three years (1980–1983) and after reopening banned many books and purged thousands of students and lecturers from the schools. The cultural revolution sometimes involved violence in taking over the university campuses. Higher education in Iran had many leftist forces who were opposed to Ayatollah Khomeini 's Islamic state in Iran. The resistance of Khomeiniist control at many universities was largely unsuccessful. How many students or faculty were killed is not known. The government's process of censoring foreign influences has not been without consequences. In addition to interrupting the freedom, education and professional livelihood of many, and striking "a major blow to Iran's cultural and intellectual life and achievement," it contributed to the emigration of many teachers and technocrats. This loss of job skills and capital weakened Iran's economy.
