In 1393 Khuzestan was conquered by Tamerlane and afterwards seems to have been ruled by his successors, the Timurids. As the Timurid rule decayed, Khuzestan was taken over by the Msha'sha'iya, a Shi'a millenarian sect who dominated the western region of the province from the middle of the 15th century to the 19th century. According to most sources, their descendants were still to be found in the 19th century, as powerful local rulers in the city of Hoveizeh, their original center.
