Indus Valley Civilization is the oldest civilization in the history of Himalayas. Archeological facts pinpoint that urban civilization bloomed from Himalaya regions like Mohenjo-daro and Harappa. As time went by and people of Himalaya habituated themselves to different modes of living, Himalayas became an active trade center especially Trans-Himalayan region. This to a greater extent is the contribution of Silk Route which brought together traders from Central Asia, South Asia and many other regions to Himalayas after Silk Route became the key destination during the early Han dynasty i.e. 206 BC to 8 AD. This bonded people from India, China, Afghanistan, Nepal, and Bhutan topographically, socially, culturally, and religiously. Himalaya gained its religion significance with the civilization of early Aryans who used to revere and worship Himalaya as the adobe of Gods and Goddess.
