The Qarmatians (Arabic: قرامطة, romanized: Qarāmiṭa; Persian: قرمطیان, romanized: Qarmatiyān) were a militant Isma'ili Shia movement 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.

Mecca was sacked by a Qarmatian leader, Abu Tahir al-Jannabi, outraging the Muslim world, particularly with their theft of the Black Stone and desecration of the Zamzam Well with corpses during the Hajj season of 930 CE.
