The present study aimed to analyse the process that caused revolutionary rationality. Revolutionary rationality supported extreme action in the years 1356-57. Shia political thought through the centuries has developed fertile and deep rationality in various fields of knowledge such as philosophy, history, mysticism and jurisprudence. "Philosophical Rationality" means that religion is interpreted with philosophy and given a philosophical form. "Jurisprudential Rationality" is the proven reason that establishes the goodness of religious rules and command. "Historical Rationality" identifies the principles and regulations behind the events of history, and "Mystical Rationality" is the expression of mystical meanings through rational style. Revolutionary rationality is rooted in the above principles. This rationality interacted with revelation and supported it, and had a relationship with other ideas, including the thought system in the old and new West, and emerged during the Islamic Revolution. Revolutionary rationality was manifested in the words of the revolutionary leaders in explaining the objective situation of society and politics, as well as in drawing the future of the revolution. The theoretical and methodological basis of this research is discourse analysis and its result, explaining the achievements of this rationality in overcoming the political order of Taghut and the birth of the Shia political order.
