Catepanate of Ras
The Catepanate of Ras (Byzantine Greek: Κατεπανίκιον Ἄρσης) was a province (catepanate) of the Byzantine Empire, established around 971 in central regions of early medieval Serbia, during the rule of Byzantine Emperor John Tzimiskes (969–976). The catepanate was named after the fortified town of Ras, eponymous for the historical region of Raška (Latin: Rascia).
