The color revolution or velvet revolution is the title of new transformation in the political arena which started in the ending decade of twenty first century from East European countries such as Czechoslovakia and Romania. It then spread to the newly independent republics of former Soviet Union such as Georgia and Kyrgyzstan.

This transformation emphasizes a soft approach to changing the governments and rulers, hence it is considered to be a new strategy for changing regimes. At the same time, the phrase soft or peaceful revolution is somehow a contradiction in terms or paradoxical, because in general, a revolution brings about fundamental changes in politics, economy, class and ideology and most of the times it is accompanied by violence.

This is while, in none of the countries in which this transformation has occurred, change at such a level is observed; in addition, the revolutionary groups have had ample emphasis on peacefulness in advancing the revolution. Paying attention to these two dimensions, meaning not seeking fundamental changes and using peaceful means, is due to the fact that the operatives and agents of these changes are, on the one hand after quick changes and taking (the government officials) by surprise and on the other hand, they want to reduce the capacity of governments for exercising violence.

These features and the success of this project in the aforementioned phases made the opposition groups in the Middle East and the United States conclude that they should execute its third phase in the Middle East.

The Cedar Revolution in Lebanon and provocations along the line of starting such movements in Iran, are worth analyzing in such framework, just as, along the continuation of this process, the Islamic Republic of Iran's opposition groups, both inside and outside, as well as the American neo-conservatives, entertain the idea of changing the regime of the Islamic Republic via such colorful revolutions. Hence, this thesis treats the analysis of quiddity and method of the taking place of this phenomenon in the countries that have been exposed to it so that the possibilities and prevention of its occurence will be evaluated in the Islamic Republic of Iran .
