The Iranian revolution in 1979 is regarded as an Islamic revolution because Ayatollah Khomeini possessed the political power. The clergy’s position is that the former government, Pahlavi, destroyed Islamic tradition and spirit, people protested against Pahlavi for Islam, and Khomeini held the political power meant the revival of Islam. Actually, the explanation of the Iranian revolution could not be seen merely via the clergy’s opinion. During 1960’s and 70’s, the Shah, Pahlavi implemented many reforms with his view of Iranian history and tradition. First, he considered ‘land reform,’ making tenants to have their own lands, could reach the justice and equality of Islam. Second, he said establishing Religious Corps is to pay respects to Islam and create a stable society. In 1971, he honored the glory of Persia with 2500-year anniversary because Modern Iran was from ancient Persia. During 1960s and 70s, the public opinion, such as discontents of religious and intellectuals, was suppressed. Hence, as Liberalization Policy in 1977 was released, the public opinion became an oppositional power. Although the Shah tried to steady protests by replacing Prime Ministers and renewing policies, there were no critical effects. Eventually, the Shah made deals with opposites and left Iran. Ayatollah Khomeini, who reached to the leading status by the resisting atmosphere, held political power. He made his status reasonable not only by speaking out what we do meets the will of Allah when drawing up the constitution or holding the referendum, but also by criticizing others who are betrayers because they are not with us. Both the Shah and Khomeini, who honored Islam, tried to establish an ideal Islamic country. However, what Khomeini did, like founding the Republic, drawing up the constitution, and proceeding elections, which were based on the system of West or Pahlavi, only the name was related to Islam. Furthermore, it’s the first time that religious had political power in Iranian history. Therefore, Khomein’s Islamic government is not the revival of tradition, was his imagination.
