1978–1979
The overthrow of the Pahlavi monarchy and the founding of the Islamic Republic of Iran
Mass protests through 1978 against Mohammad Reza Shah Pahlavi drew together clerics, bazaar merchants, secular liberals and the left, and were sustained by strikes that shut the oil industry. The Shah left Iran on 16 January 1979; Ayatollah Ruhollah Khomeini, in exile since 1964 and latterly outside Paris, flew home on 1 February to vast crowds, and the monarchy collapsed on 11 February when the armed forces declared neutrality. A referendum at the end of March approved an Islamic republic, and a new constitution installed Khomeini as Supreme Leader under the doctrine of velayat-e faqih, the guardianship of the jurist. In November 1979 students seized the United States embassy in Tehran and held its staff for 444 days, an episode that helped the revolution's clerical wing consolidate power and broke relations between the two countries.
