Ayatollah Khomeini, who died in 1989, became the founder of the Islamic Republic after returning to Tehran on Feb. 1, 1979 after living 14 years in exile. Ten days later, the government of Shah Mohammad Reza Pahlavi collapsed and the Islamic revolution was proclaimed. Khomeini later became Iran’s first supreme leader.
