The Troubled Afghan-Pakistani Border - Council on Foreign Relations

Afghanistan shares borders with six countries, but the approximate 1500-mile-long Durand Line along Pakistan remains the most dangerous. Kabul has never recognized the line as an international border, instead claiming the Pashtun territories in Pakistan that comprise the Federally Administered Tribal Lands (FATA) and parts of North West Frontier Province along the border. ----- The region that is today known as Afghanistan was long torn by ethnic and tribal rivalries. It started evolving as a modern state in the early nineteenth century when the British East India Company began expanding in the northwest of British-held India. This was also the time of the “great game”—the geopolitical struggle between the British and the Russian empires. The British held the Indian subcontinent while the Russians held the Central Asian lands to the north.
