The development of Imâmî Shî'ah during the Bûyid period

This study analyzes The Development of Imâmî Shî'ah During the Bûyid Period by examining its relationship with political authority and the institutional dynamics specific to that era. The emergence of Bûyid rule from the 4th/10th century onwards, at a time when the Abbâsid caliphate had largely lost its central power, fostered not only a political transformation but also enabled Shî'ah thought to gain social and intellectual ground. In this context, the research addresses in detail the areas in which Bûyid governance directly influenced Imâmî teachings, including the formation of new institutions, symbolic representations, and cultural expressions. The main objective of the study is to identify the transformations brought about in Imâmî thought by the Bûyids' theopolitic strategies and to demonstrate how this historical experience constituted a formative foundation for the state conception, perceptions of political legitimacy, and the construction of sectarian identity in contemporary Iran. The research focuses not only on doctrinal developments but also provides a comprehensive analysis of social practices, religious symbolism, and intradenominational debates. A wide range of primary sources has been utilized, including classical Arabic and Persian chronicles, geographical texts, and legal-theological works. These sources have been examined both through qualitative analytical methods and an interpretation of their meaning and function within their historical context. This methodological approach plays a key role in uncovering the sectarian motivations behind period narratives. Ultimately, this research reveals that Imâmî Shî'ah evolved not only as a scholarly tradition but also as a socio-political identity. In this research, the Bûyid period is presented as a critical phase in this transformation. In this respect, it aims to contribute a new perspective to the historiography of Islamic sects as well as reception of Shî'ah in Iran.
