Military history of the North-West Frontier

The North-West Frontier (present-day Khyber Pakhtunkhwa) was a region of the British Indian Empire. It remains the western frontier of present-day Pakistan, extending from the Pamir Knot in the north to the Koh-i-Malik Siah in the west, and separating the modern Pakistani frontier regions of North-West Frontier Province (renamed as Khyber Pakhtunkhwa), Federally Administered Tribal Areas and Balochistan from neighbouring Afghanistan in the west.
