Rhodope on the northeast, to the Aegean Sea and the River Aliakmon (Bistritsa) on the south, and finally to beyond the Lakes of Prespa and Ochrida on the southwest.
At the turn of the 20th century the Slavs who populated the fringe areas of Macedonia, along the Ottoman border with Serbia and scattered villages in western Macedonia as far south as Struga, Ochrida (Ohrid), and Bitola claimed to be Serbs.
They finally extinguished the Serbian Patriarchate of Pec (in Turkish Ipek--a town in Metohija) in 1766 and the Bulgarian Patriarchate of Ochrida in 1767 and completely replaced the higher Orthodox clergy with Phanariot-Greek speaking priests.
(34) We have to remark that dealing with this historical source, however, Bulgarian scholars unjustifiably appropriated ancient Scythians as "Bulgarians." Further, Bulgarian historiography claims both (i) that the cultural mission in Macedonia of Kliment, Nahum, and Angelarius was "Bulgarian" and (ii) that the famous Literary School in Ochrida from the early Middle Ages had belonged to the "Bulgarian" national and cultural inheritance.
A newly established Byzantine Archbishopric of Ochrida in 1018, by Byzantine Emperor Basil II ("Killer of Bulgarians", 976-1025), is also considered as the Bulgarian national church and called by Bulgarian nationalists the Archbishopric of Bulgaria.
In fact, the movement for the creation of the Bulgarian independent Church was enormously strengthened by the resentment caused by the sultan's abolition of the Patriarchate of Ochrida, which covered the dioceses of Macedonia and Western Bulgaria.
The borders of this Bulgaria were drawn on the southwest beyond Debar, Ochrida, Kastoria, Korcha with entrance to the Aegean Sea, but without Salonica.
