What is "guzgan"

Guzgan (Guzganan or Quzghan, in Arabic Juzjan) was the medieval term for a principality roughly centered on modern Gurziwan, Faryab Province, Afghanistan. Historically, Guzgan extended beyond the boundaries of modern Faryab and Jowzjan Province, as far as Sar-e Pol Province. The 10th century Hudud al-Alam refers to the local princes as vassals of the Samanid empire.

References to the city of Guzgan have been interpreted as referring to what is now Maimana.
