The earliest known history of the province is linked to the identification of the Samangan by Aoros Ptolemy as the place of the Varni or Uarni and the fortified city of Samangan on the banks of the Khulm River identical to the Bhaktria regi on the Dargydus river south east of Zariaspa. The ruins found here established the city's founding by Eukratides, the King of Bactria. It was then known as Edrisi the size of the Khulm city.[5][6]
