Iranian Revolution
Overview
The Iranian Revolution was a popular uprising that overthrew Mohammad Reza Shah Pahlavi in 1979, ending millennia of monarchical rule in Iran. Mass protests, strikes, and demonstrations swept the country in 1978, culminating in the Shah's flight from Iran in January 1979. Ayatollah Ruhollah Khomeini, a cleric who led resistance against the Shah's rule from exile, returned to Iran and quickly consolidated power. Within months, Iranians voted to establish an Islamic Republic, replacing the monarchy with a theocratic system of government based on Muslim clerical rule.
The Shah was unpopular for his harsh authoritarian rule and rapid Westernization, which many Iranians saw as a betrayal of their culture and religion. Resentment had been growing for decades—particularly since a 1953 CIA-backed coup removed Iran's constitutionally appointed prime minister and restored the Shah's absolute power.
The revolution established the world's first modern Islamic theocracy and intensified the rivalry between Shia Iran and Sunni Arab states, leading to proxy conflicts in Lebanon, Iraq, Syria, and Yemen that continue today. It also permanently severed relations with the United States, most notably during the 1979 hostage crisis. The regime has faced multiple phases of nationwide protests against what observers often call brutal crackdowns on dissent.
