The Shi'a Century or Shi'ite Century is a historiographical term sometimes used to describe the period between 945 and 1055, when Shi'a Muslim regimes, most notably the Fatimids and the Buyids, held sway over the central lands of the Islamic world.[1][2]
The fact that they were Shīʿite, as were the Idrīsids, Fāṭimids, and Ḥamdānids, led scholars to refer to the period from the mid-10th to mid-11th century as the Shīʿite century.
