Yaghistan
Yaghistan (Urdu: یاغستان; "The land of the rebellious and hostility") was a key frontier region between Afghanistan and British India.
This was an area where rebels lived, on either side of the Durand Line, roughly corresponding to the later tribal areas of Pakistan.
The term, in use since at least 1868, was also used in Afghanistan where Amir Abdur Rehman characterized eastern Pashtun population as "Unruly" and "Rebels".
