The Durand Line is the 2,430-kilometre (1,510 mi) international border between Afghanistan and Pakistan. It was established in 1893 between Sir Mortimer Durand, a British diplomat and civil servant of British India, and Abdur Rahman Khan, the Afghan Amir, to fix the limit of their respective spheres of influence and improve diplomatic relations and trade. Afghanistan was considered by the British as an independent princely state at the time, although the British controlled its foreign affairs and diplomatic relations. The single-page agreement, dated 12 November 1893, contains seven short articles, including a commitment not to exercise interference beyond the Durand Line. A joint British-Afghan demarcation survey took place starting from 1894, covering some 800 miles of the border.The resulting line later established the “Great Game” buffer zone between British and Russian interests in the region.The line, as slightly modified by the Anglo-Afghan Treaty of 1919, was inherited by Pakistan.
