The Principality of Ushrusana (also spelled Usrushana, Osrushana or Ustrushana) was a local dynasty ruling the Ushrusana region, in the northern area of modern Tajikistan, from an unknown date to 892 CE. Ushrusana, just like Ferghana, did not belong to Sogdia proper, but its inhabitants wrote in Sogdian, and may have spoken the Sogdian language as well. The rulers of the principality were known by their title of Afshin.
