This research examines the nature of the relationship between the Buyid and Fatimid states during the fourth and fifth centuries AH, a topic that, to the best of our knowledge, has not received independent study in historical research.

It begins with a central question: whether actual relations existed between the two states, and if so, what their nature was—whether religious, political, economic, or social. It also explores whether these relations were direct or indirect, overt or covert, stable or fluctuating. Furthermore, it analyzes the factors that contributed to the emergence of these relations or led to their rupture, highlighting the influence of the shared religious structure between the two states, particularly their convergence on Shi'a identity, in shaping the frameworks of cooperation or rivalry between them.

The study employs a historical inquiry methodology and comparative analysis, tracing events, analyzing texts and scattered historical references in primary sources, and examining the influential political figures who shaped the course of these relations. Some preliminary findings indicate that relations between the two states were limited and intermittent, governed by the balance of power in overlapping spheres of influence and the convergence of their interests. Certain manifestations of religious openness—which we will examine later—particularly in their political dimension, emerged during periods of strength, while other periods were characterized by tension or hostility, especially with the Fatimids' religious and political expansion in Iraq. The research also reveals a clear economic influence on the relationship between the two states, with a near-complete absence of social ties.

The research concludes that Buyid-Fatimid relations were selective and pragmatic, characterized at times by ambiguity and at others by an overlap between religious and political considerations. These relations represent a telling model of the mechanisms of power and alliances in the Islamic world during that period.
