Buddhism becomes the dominant cultural force in Tibet, superceding the indigenous Bon religion. Buddhist monasteries emerge as religious, political, and economic centers. By 1200, Buddhism has all but disappeared from India, which for centuries had served as the source of religious texts and teachings for surrounding cultures. Tibetan Buddhism is firmly established, with four major lineages: Nyingmapa, Kagyupa, Sakyapa, and Kadampa. Political disunity continues in Tibet until around 1250, when the Sakya order—with Mongol support—becomes dominant. In Nepal, Buddhism no longer receives much royal patronage, but continues to flourish alongside Hinduism. Buddhist and Hindu arts in all forms—painting, sculpture, metalwork—flourish in Nepal during this period. Art in Tibet is mainly Buddhist but some continues to be made for the Bon. In the early fifteenth century, the Gelugpa school is founded in Tibet and will become the dominant religious and political force there.
