The impact of the Fatimid-Seljuk conflict on the Seljuk-Crusader conflict during the 5th and 6th centuries AH (11th and 12th centuries AD)

Abstract

This research, entitled "The Impact of the Fatimid-Seljuk Conflict on the Seljuk-Crusader Conflict," examines the period during the 5th and 6th centuries AH (11th and 12th centuries CE). It studies a significant chapter in Islamic history, a period marked by numerous external invasions throughout the ages. The research focuses on the political and sectarian disputes and conflicts among Islamic powers before and during the Crusades, and the extent to which these disputes influenced the balance of power and the outcomes of confrontations between the Seljuks and the Crusaders. It also explores Fatimid-Crusader relations within the context of the Fatimid-Seljuk conflicts, and the role of esoteric Shi'a sects, specifically the Nizari Assassins, in hindering resistance against the Crusaders by assassinating Muslim jihad leaders.
