Tibetan Buddhism
Tibetan Buddhism is practised throughout the Himalayan region, and, indeed, throughout the world. It dates back to the royal period of the so-called 'Yarlung dynasty', especially the time of King Trisong Deutsen, during whose reign great masters like Shantarakshita, Guru Padmasambhava and Vimalamitra were invited to Tibet, and the country's first monastery was founded at Samyé. Several schools developed over the following centuries, the foremost among them being the Nyingma, Sakya, Kagyü and Gelugpa.
