Danger Along the Durand Line -- PATRICK SEALE

The Durand Line was a British creation. It was demarcated and then signed into a treaty on Nov. 12 1893, between the ruler of Afghanistan, Amir Abdul Rahman Khan, and Sir Mortimer Durand, foreign secretary of what was then British India.

The idea was to create a buffer zone to protect British India from possible Czarist Russian aggression in what was then the "Great Game" between the British and Russian empires. When British India was partitioned between India and Pakistan in 1947, the Durand Line was recognized as the Pakistan-Afghan border.
