The Khyber Pass is a mountain pass that links Afghanistan and Pakistan. Throughout its history it has been an important trade route between Central Asia and South Asia, and is a strategic military location. It is the route used by Alexander the Great, Cyrus the Great, Genghis Khan, Babur the Tiger, Chandragupta Maurya, Darius I and countless other would-be conquerors. The Afghan Shinwari clan, who live in the Pass, regarded the Pass as their own preserve and have levied a toll on travelers for safe conduct.
