Movement of Imam Khomeini (r.a.) 3

Founding the Islamic Republic of Iran
The third phase of Khomeini's life began with his return to Iran from exile on February 1, 1979, after Muhammad Reza Shah had been forced to step down two weeks earlier. On February 11 revolutionary forces loyal to Khomeini seized power in Iran, and Khomeini emerged as the founder and the supreme leader of the Islamic Republic of Iran.
From the perspective of Khomeini and his followers, the Iranian Revolution went through several "revolutionary" phases. The first phase began with Khomeini's appointment of Mehdi Bazargan as the head of the "provisional government" on February 5, 1979, and ended with his fall on November 6, two days after the capture of the U.S. embassy (the U.S. headquarters in Iran).
The second revolution was marked by the elimination of mainly nationalist forces, or forces devoted to the interests of a culture. As early as August 20, 1979, twenty-two newspapers that clashed with Khomeini's views were ordered closed. In terms of foreign policy, the landmarks of the second revolution were the destruction of U.S.-Iran relations and the admission of the shah to the United States on October 22, 1979. Two weeks later, Khomeini instructed Iranian students to "expand with all their might their attacks against the United States" in order to force the extradition (legal surrender) of the shah. The seizure of the American embassy on November 4 led to 444 days of agonizing dispute between the United States and Iran until the release of the hostages on January 21, 1981.
The so-called third revolution began with Khomeini's dismissal of President Abul Hassan Bani-Sadr on June 22, 1981. Bani-Sadr's fate was a result of Khomeini's determination to eliminate from power any individual or group that could stand in the way of the ideal Islamic Republic of Iran. This government, however, had yet to be molded thoroughly according to his interpretation of Islam. In terms of foreign policy, the main characteristics of the third revolution were the continuation of the Iraq-Iran war, expanded efforts to export the "Islamic revolution," and increasing relations with the Soviet Union, a once-powerful nation that was made up of Russia and several other smaller nations.
The revolution began going through yet a fourth phase in late 1982. Domestically, the clerical class had combined its control, prevented land distribution, and promoted the role of the private citizens. Internationally, Iran sought a means of ending its status as an outcast and tried to distance itself from terrorist groups. It expanded commercial relations with Western Europe, China, Japan, and Turkey and reduced interaction with the Soviet Union. Iran also claimed that the door was open for re-establishing relations with the United States.
