Dardic languages
Kashmiri spoken in north east Azad Kashmir and the adjacent Kashmir valley, (not to be confused with Pahari language spoken in the lower Azad Kashmir) is one of the Dardic languages that has a literary tradition that goes well back into the history whereas other Dardic languages spoken in northern Pakistan, do not have written literature. It is believed to be the result of the northern areas of Pakistan having remained isolated in the mountain valleys from the others for centuries.
