The Himalayas are the highest mountain ranges in the world, and from them flow the major rivers of Asia. The kingdoms of Nepal and Bhutan are located along the Himalayan ranges, and the Tibetan plateau lies to their north. Although the Himalayas are nearly impassible, many peoples have managed the crossing and left traces of their cultures.
Surrounded by high peaks with only a few passes, the plateau of Tibet was home to people who developed their own, distinct culture, which was highly influenced by Buddhism. That religion came into Tibet in two waves: from India, Nepal, and China in the seventh century, and again from India in the eleventh century.
