Durand Line
The Durand Line is the international  land border between Afghanistan and Pakistan in South-Central Asia. It was established after an 1897 memorandum of understanding (MoU) between Mortimer Durand of British India and Afghan Amir Abdur Rahman Khan.  Referred to as a frontier line, it is named after Mortimer Durand, who was the Foreign Secretary of colonial British India at the time. Later, Abdur Rahman Khan's successor, Amir Habibullah Khan signed a new agreement with Britain which again confirmed the legality of the Durand Line. King Amanullah Khan also accepted Durand line as international border between Afghanistan and British India after signing the Anglo-Afghan treaty of 1919. Article 5 of this treaty, on the basis of which Afghanistan reclaimed its independence, says that Afghanistan accepted all previously agreed border arrangements with British India.  Hence, Afghanistan as an independent country recognized Durand line as an international border.
