This tendency among the Shi‘a to exaggerate the status of the family of the Prophet and to adopt esoteric interpretations of religious texts is referred to as extremism ( ghuluw ) and those who display it are called extremists ( ghulat )by Sunnis. Out of this chaos emerged the more moderate Shi‘a in the form of Twelver (or Imami) Shi‘ism, whose name is based on the recognition of twelve descendants of the Prophet as rightful heirs to leadership of the community. Twelver Shi‘is came very close to Sunnis on a range of issues,and their legal school, the Ja‘fari school, has relatively few areas of major interpretative difference with the main Sunni legal schools. Several Shi‘i rebellions were put down by the Umayyads (41–134/661–750) and theirgovernors, thus laying the foundation of a bloody history of persecution between Shi‘i and Sunni Muslims.
