When Islamic Revolution burst...
When Islamic Revolution burst, the Imam Khomeini expressed his intention to fight against tyranny (the shah's), dependence on foreign powers, and corruption and to institute a society based on Islamic principles: "the idea that religion must break up with Politics and Muslim scientists should not get involved in political and social affairs is a strategy launched by colonialists.
Not only that Islam isn't separated from Politics but even it is the religion of Politics, prayers having political substance." Dr. Abolhamid from the University of Teheran appreciated that: "Islamic revolution corresponds to a fundamental change both in social, moral, economic, juridical sphere and moreover in the political one. Violence is often used in removing a political regime, situation which causes human victims.
In Khomeini's opinion, the origin of Islamic Revolution should be regarded from Iranian and Lebanese Shifts' point of view that supported the Islamic renaissance. Three fundamental principles lie at the basis of this concept and they are: the Islamic constitutional movement; the spread of Islam; martyrdom. In Iran, the 1906 constitutional revolution was the symbol of the confrontation between Islamic culture and tradition and occidental values.
Due to the misunderstandings between modern fundamentalists and conservationists-traditionalists regarding to the establishment of the Islamic state, constitutional revolution was soon over, making way to anarchy. In these circumstances, in 1911, Russia supported the institution of a dictatorship regime. After the assassination of two representatives of the Iranian Clerics, in 1961 and 1962, Imam Khomeini became marji al-taghid, the supreme juridical and religious authority.
In 1963, he made reference to the Islamic revolution and asked people to adhere to his ideas. In 1979, Imam Khomeini proclaimed the Islamic republic in Iran and Islam became state religion, the Islamic state being ruled by an Imam who would impose, by governing, the basic principles of Islam. According to the great ayatollah Mohamed Bakr Al-Sadr, the Islamic governing shouldn't rely on Individualism and the uninvolvement of the individual in the society or on the imperialists or social values.
The Islamic state is similar to God's state, it is neither absolutist or tyrannical to respect the rules mentioned in the Coran being a must for the governors.
