The following is a list of extinct sects of Shia Islam. These are branches of Shia that no longer have any living followers or practitioners. These sects were created around certain beliefs that were unorthodox or otherwise not held by the majority of Shia Muslims. These sects eventually after their very brief existence had their followers fall into mainstream Shiaism.
* Bayaniyya- the followers of Bayān al-Nahdi, who believed that Abu Hashim was a prophet and would return to rule the world as Mahdi. Bayān claimed prophethood for himself after the demise of Abu Hashim, as well.
* Harbiyya- the followers of ʿAbd Allāh ibn al-Harb ibn al-Kindi, who initially taught antinomianism then joined Ibn Mu'awiya's party and later expressed many extremist views about him. Furthermore, Ibn al-Harb introduced some fundamental doctrines including metempsychosis, cyclical history of eras and aeons into the radical branch of Shi'ism. The group claimed that Abu Hashim designated Ibn Mu'awiya as his successor Imam of Hashimiyya.
** Riyahiyya- Harbiyya and pro-Abbasid Hashimiyya disputed over Abu Hashim's will about the imamate and eventually the disputed parties agreed upon the arbitration of their respected leader Abu Riyah, who decided that the imamate should remain in Abbasids. The most of the followers of Harbiyya, who had previously recognized Ibn Mu'awiya as their imam, seceded and joined to the Abbasid party and they had been called Riyahiyya. Those who stayed in Harbiyya and continued to recognize the imamete of Ibn Mu'awiya subsequently called as Janahiyya.
Mughiriyya- who influenced by Mandean and Manichean doctrines, founded by the first Shi'i gnostic al-Mughira, who claimed that God is a man of light with a crown of light on his head resembling Mandean doctrine of deity referred to as "king of light". Al-Mughira further added that God has limbs corresponding to the letters of Arabic alphabet reminiscent of the teaching of Marcus the Gnostic.
Mutrafya A Hamdani based sect of the Zaydi Shia led Mutraf bin Shihab that start gaining followers in Yemen after the fall of the Ismaili Zurayids, they were weakened by Sunni Ayyubids & later famously exterminated as heretics by the Zaydi imam Al-Mansur Abdallah for calling for backing a Hamdani imam
