  The Shia community throughout its history split over the issue of the Imamate. The largest branch are the Twelvers, followed by the Zaydīs and the Ismāʿīlīs. Each subsect of Shīʿīsm follows its own line of Imamate. All mainstream Twelver and Ismāʿīlī Shia Muslims follow the same school of thought, the Jaʽfari jurisprudence, named after Jaʿfar al-Ṣādiq, the 6th Shīʿīte Imam. Shīʿīte clergymen and jurists usually carry the title of mujtahid (i.e., someone authorized to issue legal opinions in Shia Islam).
