Descendants of the Imams (sādāt) in the Umayyad period were in coordination with the Abbasids in opposition to the ruling system, until in 132/749 the Abbasids caused the collapse of the Umayyad rule with the slogan “Al-Rizā min Āl-i Muhammad” (Al-Rizā [A.S.] is from the household of Muhammad [S.A.W.]). Once the Abbasids took office, the Alavids were suppressed. Considering themselves as involved in toppling the Umayyads, the sādāt launched movements against the Abbasid’s caliphate. When the Abbasids took over the caliphate, the Hasanī branch of the movement played a more active and extensive role against the Abbasids. The further the Abbasid caliphate went on, the more considerable and outstanding the Husaynī sādāt participated in the opposition against the ruling system, to the extent that, in Ma’mūn’s period, both branches of the Hasanī and Husayī sādāt took up a more active role together in confronting the government (hukūma).
