Administrative divisions of medieval Serbia

Administrative divisions of medieval Serbia refer to regional administrative divisions of Medieval Serbia, from the 7th to the 15 the century.
Serbian Principality and Principality of Duklja.
The Byzantine Empire called the lands of the South Slavs "Sclaviniaes" (from the Sclaveni, the Southwestern branch), and they were initially outside Imperial control. By the second half of the 7th century, most of the Slavs in proximity to Byzantium had recognized the Emperor's supreme rule.
The prince ("archon") that led the Serbs to the Balkans and received the protection of Heraclius (r. 610–641), known conventionally as the "Unknown Archont", was an ancestor of the Vlastimirović dynasty. The Serbs at that time were organized into "župe", a confederation of village communities (roughly the equivalent of a county), headed by a local "župan" (a magistrate or governor). According to Fine, the governorship was hereditary, and the "župan" reported to the Serbian prince, whom they were obliged to aid in war. Emperor Constantine VII "Porphyrogenitus" (r. 913–959) mentions that the Serbian throne is inherited by "the son", i.e. the first-born, though in one occasion there is a triumvirate in his enumeration of monarchs.
Višeslav, the first Serbian monarch known by name, was a contemporary with Charlemagne (fl. 768–814). He directly held the hereditary lands of Neretva, Tara, Piva and Lim. Radoslav, then Prosigoj, succeeded Višeslav, and they ruled during the revolt of Ljudevit Posavski against the Franks (819–822). According to the Royal Frankish Annals, written in 822, Ljudevit went from his seat at Sisak to the Serbs somewhere in western Bosnia, who controlled the greater part of Dalmatia: "ad Sorabos, quae natio magnam Dalmatiae partem obtinere dicitur".
The Serbs established several future principalities by the 10th century: "Serbia" (roughly the later province of "Rascia", including Bosnia; part of "Zagorje" - "hinterlands"); and Pagania, Zachlumia, Travunia (including Kanalitai) and Dioclea (part of "Pomorje" - "maritime").
