The Khyber Pass, (altitude: 1,070 m or 3,510 ft) is a mountain pass connecting Afghanistan and Pakistan, cutting through the northeastern part of the Spin Ghar mountains. An integral part of the ancient Silk Road, it is one of the oldest known passes in the world. Throughout history it has been an important trade route between Central Asia and South Asia and a strategic military location. The summit of the pass is 5 kilometres (3.1 mi) inside Pakistan at Landi Kotal.

The commanders who crossed the Khyber Pass all led armies eastward in the conquest of India, except for Chandragupta Maurya, Shah Jahan, Ranjit Singh, George Pollock and General Sir Samuel James Browne VC who crossed in the opposite direction.
