"During the reign of Anastasius, Bulgars started to conquer this land, they passed to Bъdyne [Vidin] and firstly begun to conquer the Lower land of Ohrid and later all of it."
--Bulgarian translation of the Manasios Chronicle made during the reign of John-Alexander, 14th c.
According to early historical sources, Bulgars settled permanently in Srem and Singindunum (Belgrade) since the 5-6th century AD. Consequently, soon after that, Bulgars settled the territory of old Macedonia – dolna zemya ohridska [the Lower Land of Ohrid]. According to scripts left by the Turnovo kings, Bulgars settled Macedonia at the beginning of the 6th century, at the time of Emperor Anastasios.
