The Kaysaniyya Sect: Its Origins and Development

Abstract

This research traces the trajectory of the Kaysaniyya sect, one of the oldest Shi'a sects, which formed as a direct reaction to the martyrdom of Imam Hussein ibn Ali at Karbala in 61 AH/680AD, the sect arose in a turbulent political and social environment, characterized by a desire for revenge and the exploitation of widespread discontent against Umayyad rule. It found its practical expression in the Mukhtar al-Thaqafi revolt, which seized control of Kufa between 66 -67 AH/ 685-686AD.In its early stages, the Kaysaniyya sect was based on three main figures: Mukhtar al-Thaqafi as a military and political leader, Muhammad ibn al-Hanafiyya as a presumed religious authority, and Kaysan, a freed slave of Ali ibn Abi Talib, as a founding symbol. The sect developed early on new doctrinal concepts within Shi'a thought, most notably the declaration of the Imamate of Muhammad ibn al-Hanafiyya (who was not the son of Fatima al-Zahra), and the development of the doctrine of the Hidden Imam, whom they believed to be alive on Mount Radwa and who would return to fill the earth with justice. The Kaysaniyya sect underwent a significant transformation after the death of Muhammad ibn al-Hanafiyya, splitting into several factions. The most important of these was the "Hashimiyya" faction, which believed in the imamate of his son, Abu Hashim. This faction formed a crucial historical bridge when, according to historical accounts, Abu Hashim recommended supporting the Abbasids, thus granting the Abbasid revolution legitimacy and the organizational structure that contributed to the downfall of the Umayyad Caliphate.During the Abbasid era, the Kaysaniyya lost its political influence after the Abbasids exploited and then abandoned it. It transformed into extremist doctrinal groups like the "Harbiyya," and began to decline due to the rise of more organized Shi'a sects such as the Twelver Shi'a, its inability to develop a lasting jurisprudential tradition, and its failure to achieve its core revolutionary goals of revenge and the overthrow of the Umayyad Caliphate.
