Unknown Archon

The term Unknown Archon, Unknown Prince, or Unnamed Serbian Archon (Serbian: Непознати архонт / непознати кнез / неименовани српски архонт, Nepoznati arhont / nepoznati knez / neimenovani srpski arhont) refers to a prince of the Sorbs of the first half of the 7th century who supposedly led his people from their original homeland in White Serbia to settle in the Balkans during the reign of Byzantine Emperor Heraclius (610–641), as mentioned in Emperor Constantine VII's work De Administrando Imperio (written in 950s). The work does not record his name, but states that he was the progenitor of the first Serbian dynasty (known in historiography as the Vlastimirović dynasty), and that he died before the arrival of the Bulgars on the Balkans (680), succeeded by his son, and then grandson.
