Traditionally, the sociology scholars tend to ignore or underestimate the role played by ideology is social phenomena, and this tendency can be seen among the political sciences scholars as well. Robert Jervis believes that one of the reasons for weakness of analysis of terrorism based on ideology is ignorance of this case in texts and literature of liberal arts and specifically political sciences and international relations: “Terrorism based on ideology has created some challenges for modern political sciences because less attention has been paid to discussions related to ideology, and the experts in this realm are less interested in them”. But the evolutions during the last decades of the 20th century and such events as the Islamic revolution of Iran increased the level of attention to this forgotten factor. In fact, for the first time a revolution with religious and ideological components happened across the world that surprised the thinkers in this scope and caused them to consider religion and ideology as two influential variables in their calculations. The present paper attempts to theoretically study the manner of formation of terrorism based on ideology.
