[pas, pahs]
pass, opening or way by which a natural or artificial barrier can be crossed. The term pass is usually applied to a relatively narrow passage through a mountainous region. A pass, like an isthmus, may have great strategic and economic importance; the history of a nation has often been determined by its success or failure in defending a pass, and land trade routes must necessarily cross passes. In the Alps, Saint Bernard, Simplon, and Saint Gotthard are important; in the Caucasus, Daryal is traversed by a great military road; in Asia, Khyber Pass into India and the passes of the Himalayas, Karakorum, and other ranges are important.

Pass in the Spīn Ghār (Safīd Kūh) Range on the border between Afghanistan and Pakistan. About 33 mi (53 km) long, it has historically been the gateway for invasions of the Indian subcontinent from the northwest; it was traversed by Persians, Greeks, Mughals, and Afghans from the north and by the British from the south. The Pashtun Afridi people of the Khyber area long resisted foreign control, but during the Second Anglo-Afghan War in 1879, the Khyber tribes came under British rule. It is now controlled by Pakistan.
