Khyber Agency is the most famous agency amongst seven others in the Federally Administered Tribal Areas (FATA). Khyber Agency derives its name from the famous Khyber Pass, which has served as a historical trade route, connecting the Asian sub-continent with the rest of Central Asia, via Afghanistan. Because of its geographical location, the agency has a history dating back thousands of years. The Khyber Pass has been used by the Aryans in 1600 B.C., the Persians in 600 B.C., Alexander in 326 B.C. and subsequently, by Changez Khan, Taimurlang, the Mehmood of Ghazni and the Mughals.
