Zaydiyyais a branch of theShiaarising out of the abortive revolt of Zayd b. Ali b. al-Husayn in Kufa in 122 AH / 740 CE. During the preparations for the revolt, a part of the KufanShiawithdrew their support from Zayd in protest against his refusal to condemn unconditionally the early caliphs preceding Ali and backed Zayds nephew Jafar al-Sadiq as theirimamIn general usage, a leader of prayers or religious leader. The Shi’i restrict the term to their spiritual leaders descended from 尪Al蘋 b. Ab蘋 廜珀lib and the Prophet’s daughter, Fatima.. This schism led to a lasting division of theShiainto a radical and a moderate wing in terms of their religious break with the Sunni Muslim community. TheZaydiyya, as the moderates, did not classify the Sunni Muslims generally as infidels. In political terms, however, they were, in contrast to the radical but quietistImamiyya, militant, espousing revolt against the illegitimate Sunni rule as a religious duty.
