TWELVER SHIA
Of the several Shia sects, the Twelve Imam or Twelver (ithna- ashari), is dominant in Iran; most Shia in Bahrain, Iraq, and Lebanon also follow this sect. All the Shia sects originated among early Muslim dissenters in the first three centuries following the death of the Prophet Muhammad in A.D. 632. [Source: Library of Congress, December 1987 *]
The principal belief of Twelvers, but not of other Shia, is that the spiritual and temporal leadership of the Muslim community passed from Muhammad to Ali and then sequentially to eleven of Ali’s direct male descendants, a tenet rejected by Sunnis. Over the centuries various other theological differences have developed between Twelver Shia and Sunnis.
