Primary data have been extensively used to explain the real and true perspective of this border. This frontier was demarcated by joint boundary commissions from time to time. Reports of British commissioners have been consulted and quoted. This is perhaps for the first time that these reports were explored and utilized. It is generally believed that Ameer Abdur Rahman signed the treaty under “duress”. This book dispels the impression. It also contains the history of Balochistan, Khyber Pakhtunkhwa’s tribal districts (former FATA), and the former princely states of Chitral, Dir, and Swat. Different phases of Afghan history and status of the Durand Agreement under international law have also been discussed. Furthermore, international conventions have been cited to elucidate the issue and to facilitate the readers.
