Buddhism was first actively disseminated in Tibet from the 7th to the 9th century CE, predominantly from India. During the Era of Fragmentation, Buddhism waned in Tibet, only to rise again in the 11th century.

From the 14th to the 20th Tibetan Buddhism was patronized by the Chinese Ming dynasty (1368–1644) and the Manchurian Qing dynasty (1644–1912).
