Around 2800 BC, a new civilization rose along the banks of the Indus river (just like other early civilizations, along a river) in India. The place in which it arose was largely ideal, and was well-protected by the natural boundaries of the Hindu Kush Mountains. Although this limited outside contact, it is known that the early Indians used the Khyber pass through this range to communicate with other civilizations. In the future, groups would use this same pass to invade India.
