Dardistan

[2] The initial efforts by the British grouped almost all the people and languages of the upper Indus River, between Kashmir and Kabul, into a single category.

This led to the creation of distinct identities for all other groups in the region, giving rise to terms such as Dard, Dardistan, and Dardic.

[6] In academic linguistic contexts, however, Kohistani refers to one subgroup of Dardic languages which is mainly spoken in Kohistan district of Khyber Pakhtunkhwa.

[14] Biddulph acknowledged that Leitner's label 'Dardistan' was based on a misunderstanding, but he accepted it as a useful term for referring to the complex, diverse, and largely unexplored Karakoram region between Kashmir and the Hindukush Range.

[15] Interestingly, this usage mirrors the Sanskrit interpretation, where it refers to unspecified fierce outsiders residing in the mountainous regions beyond the area's borders.
