Tibet is popularly known as the Roof of the World because of its great elevation and as Forbidden Land since nobody went there because of difficult terrain and entry to outsiders was generally opposed by its leaders. The eco-cultural situations of the Tibet had developed its own traditions, customs, institutions and beliefs and thus a typical society and culture. The Tibetans were self contended and happy, and had struggled hard to preservge their cultural identity, institutions, religion, etc., ever since the 6th century. This valuable culture of Tibet which had developed preserving its peculiar qualities and differences from the rest of the world cultures was tremendously disturbed by China by flooding her own population and culture into Tibet. The sinonization took place at various levels of Tibetan culture by force, violence, indoctrination and such other means. Because Tibet remained isolated, and so failed to impress the outside world about its independent existence. The Chinese advent followed by the 1959 revolt in Tibet disturbed the calm and orderly society and resulted in the fleeing of H.H. the Dalai Lama along with about 80,000 Tibetan souls as refugees to India, Nepal and Bhutan.
