A basis for the internal conflicts in Iran in the 1970s was the weakness of the Shah.

Explanation:

The Iranian Revolution was a multi-faceted movement that led to the ousting of Shah Mohammad Reza Pahlavi in 1979 and the end of the monarchy in Iran. Its symbolic figure and later revolutionary leader was the Ayatollah Khomeini.

Following political pressure from US President Jimmy Carter in 1977, the Khomeini-led demonstrations began in January 1978. Between August and December 1978, strikes organized with support from the National Front paralyzed the country's economy. The Shah left the country in mid-January 1979, and two weeks later Ayatollah Khomeini, who had been deported abroad in 1964, returned from his exile in France to Tehran, where he was greeted by a jubilant crowd. The constitutional monarchy finally collapsed on February 11, 1979 when guerrilla groups and armed Islamist revolutionaries attacked the shah-loyal sections of the army in street fighting.
