The Khyber Pass

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.

History

Well known invasions of the area have been predominantly through the Khyber Pass, such as the invasions by Darius I and Alexander the Great and also include Genghis Khan and later Mongols such as Duwa, Qutlugh Khwaja and Kebek. Among the Muslim invasions of South Asia, the famous invaders coming through the Khyber Pass are the Afghans such as Mahmud Ghaznavi, Muhammad Ghori and the Turkic-Mongols. Finally, Sikhs under Ranjit Singh, in 1798 captured the Khyber Pass. 

Hari Singh Nalwa, who manned the Khyber pass for years became a household name in Afghanistan.

To the north of the Khyber Pass lies the country of the Mullagori tribe. To the south is Afridi Tirah, while the inhabitants of villages in the Pass itself are Afridi clansmen. Throughout the centuries the Pashtun clans, particularly the Afridis and the Afghan Shinwaris, have regarded the Pass as their own preserve and have levied a toll on travellers for safe conduct. Since this has long been their main source of income, resistance to challenges to the Shinwaris' authority has often been fierce.

For strategic reasons, after the First World War the British built a heavily engineered railway through the Pass. The Khyber Pass Railway from Jamrud, near Peshawar, to the Afghan border near Landi Kotal was opened in 1925.

During World War II concrete "dragon’s teeth" (tank obstacles) were erected on the valley floor due to British fears of a German tank invasion of India. The Pass became widely known to thousands of Westerners and Japanese who traveled it in the days of the Hippie trail, taking a bus or car from Kabul to the Afghan border. At the Pakistani frontier post, travelers were advised not to wander away from the road, as the location was a barely controlled Federally Administered Tribal Area. Then, after customs formalities, a quick daylight drive through the Pass was made. Monuments left by British Army units, as well as hillside forts, could be viewed from the highway.

The area of the Khyber Pass has been connected with a counterfeit arms industry, making various types of weapons known to gun collectors as Khyber Pass Copies, using local steel and blacksmiths' forges.
