Quhistan

For other areas named Kohistan, see Kohistan

Quhistan or Kohistan (Persian: کوہستان‎ 'mountainous land') was a region of medieval Persia, essentially the southern part of Greater Khorasan. Its boundaries appear to have been indeterminate, and the term generally seems to have been applied loosely.

The area tended to be ruled either as part of Khurasan or as a province with its capital at Herat. It did, however, experience some periods of autonomy.
