Land routes have an important part of the economic and cultural dynamics in India since ancient times.
The three main contributions of land routes are:
1. Trade flourished through the land trade routes. The Silk route passing through the Himalayas is an excellent example.
2. Land routes enabled the expansion of scientific knowledge; important breakthroughs in science, technology, and mathematics were communicated to far across lands through ancient routes.
3. The land routes also helped in the understanding of the cultures and traditions of other nations across the world.
