The
Jonang is one of the schools of
Tibetan Buddhism. Its origins in Tibet can be traced to early 12th century master
Yumo Mikyo Dorje, but became much wider known with the help of
Dolpopa Sherab Gyaltsen, a monk originally trained in the
Sakya school. The Jonang school was widely thought to have become extinct in the late 17th century at the hands of the
5th Dalai Lama, who forcibly annexed the Jonang
monasteries to his
Gelug school, declaring them heretical.
