Durand Line

The Durand Line is the long line between Afghanistan and Pakistan. It was established in 1893 by agreement 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 ceded various frontier areas to British India to prevent invasion of further areas of the country. Afghanistan was considered by the British as an independent princely state at the time, although the British controlled its foreign affairs and diplomatic relations.
