Iranian Revolution

11 Feb
On this day the Iranian people's decades-long struggle against the regime of the former dictator Mohammad Reza Pahlavi paid off.

The Iranian Revolution (also known as the Islamic Revolution of Iran or the 1979 Revolution refers to events involving the overthrow of the Pahlavi dynasty under Mohammad Reza Shah Pahlavi, who was supported by the United States, and its eventual replacement with an Islamic republic under the Grand Ayatollah Ruhollah Khomeini, the leader of the revolution, supported by various leftist and Islamic organizations and Iranian student movements. While the Soviet Union immediately recognized the new Islamic Republic, it did not actively support the revolution, initially making efforts to salvage the Shah's government.
Demonstrations against the Shah commenced in October 1977, developing into a campaign of civil resistance that was religious based (with secular elements). and intensified in January 1978. Between August and December 1978 strikes and demonstrations paralyzed the country. The Shah left Iran for exile on January 16, 1979 as the last Persian monarch, leaving his duties to a regency council and an opposition based prime minister. The Ayatollah Khomeini was invited back to Iran by the government, and returned to Tehran to a greeting by several million Iranians.The royal reign collapsed shortly after on February 11 when guerrillas and rebel troops overwhelmed troops loyal to the Shah in armed street fighting, and bringing Khomeini to official power. Iran voted by national referendum to become an Islamic Republic on April 1, 1979, and to approve a new theocratic-republican constitution whereby Khomeini became Supreme Leader of the country, in December 1979.
The revolution was unusual for the surprise it created throughout the world: it lacked many of the customary causes of revolution (defeat at war, a financial crisis, peasant rebellion, or disgruntled military), occurred in a nation that was enjoying relatively good material wealth and prosperity, produced profound change at great speed, was massively popular, resulted in the exile of many Iranians, and replaced a pro-Western semi-absolute monarchy with an anti-Western authoritarian theocracy based on the concept of Guardianship of the Islamic Jurists (or velayat-e faqih). It was a relatively non-violent revolution, and helped to redefine the meaning and practice of modern revolutions (although there was violence in its aftermath).
