John Skylitzes
Mihailo Vojislavljević succeeded as Knez of "Duklja" in 1046, or as his realm was called by contemporary Cedrenus: "Triballorum ac Serborum principatum". According to George Kedrenos (fl. 1050s) and John Skylitzes (fl. 1057), he was the "Prince of Triballians and Serbs" (Τριβαλλών και Σέρβων...αρχηγός/ Τριβαλλῶν καὶ Σέρβων...ἀρχηγός).
