Ismaili dynasties

The Qarmatians were an Isma'ili Shia militant movement led by a dynasty of Persian descent, centred in Al-Ahsa in Eastern Arabia, where they established a religious state in 899 CE. Its members were part of a movement that adhered to a syncretic branch of Sevener Ismaili Shia Islam, and were ruled by a dynasty founded by Abu Sa'id al-Jannabi. They rejected the claim of Fatimid Caliph Abdallah al-Mahdi Billah to imamate and clung to their belief in the coming of the Mahdi, and they revolted against the Fatimid and Abbasid Caliphates.
