The Khyber Pass is a mountain pass in the north of Pakistan. Originally part of the Silk Road, it has long been a key trade route between Central Asia and the Indian subcontinent and a military location.
On 26 May 1879, the Treaty of Gandamak was signed by Afghanistan and Britain. The treaty signed over formerly Afghan territories, like the Khyber Pass, to India; allowed a British mission to be permanently stationed in Afghanistan; established British control of Afghan foreign policy; and opened up Afghanistan to free trade with India. In exchange, formerly occupied territories were returned to Amir Yaqub Khan and he and his heirs were granted a subsidy. Image: Photo of Mohammad Yaqub Khan, Emir of Afganistan.
