Tibetan Buddhism is a form of Buddhism practiced in Tibet, Bhutan and Mongolia. It also has a sizable number of adherents in the areas surrounding the Himalayas, including the Indian regions of Ladakh, Darjeeling, Sikkim, and Arunachal Pradesh, as well as in Nepal. Smaller groups of practitioners can be found in Central Asia, some regions of China such as Northeast China, Xinjiang, Inner Mongolia and some regions of Russia, such as Tuva, Buryatia, and Kalmykia.
Tibetan Buddhism evolved as a form of Mahayana Buddhism stemming from the latest stages of Buddhism (which included many Vajrayana elements). It thus preserves many Indian Buddhist tantric practices of the post-Gupta early medieval period (500–1200 CE), along with numerous native Tibetan developments. In the pre-modern era, Tibetan Buddhism spread outside of Tibet primarily due to the influence of the Mongol-led Yuan dynasty, founded by Kublai Khan, who ruled China, Mongolia, and parts of Siberia. In the Modern era, Tibetan Buddhism has spread outside of Asia because of the efforts of the Tibetan diaspora (1959 onwards). As the Dalai Lama escaped to India, the Indian subcontinent is also known for its renaissance of Tibetan Buddhism monasteries, including the rebuilding of the three major monasteries of the Gelug tradition.
