History of Islamic Sects is a discipline which has succeeded in forming its own tradition at a very early stage during the organizational process of Islamic ideology. It is a branch of social sciences, which examines the emerging environment of the humanitarian and social organizations that can be called as "Islamic Thought Ecoles" formed by some political and religious aims in the past and present and the possible reasons of their emergence, organizational processes, basic tenets, members, literary works, dominant regions and their contributions to the Islamic thought, within the context of time, space and the scope of links between ideology-incidents, by using a descriptive method and objective viewpoint. The tradition of Malakat and Firak that emerged in the early periods of Islamic Thought and which have their own unique methods, literature and points of view, have been ignored over time although they once had an active determining status in terms of basic Islamic sciences.
