Ivan Vladislav in the context of "Macedonian Bulgarian"

Macedonians (Bulgarian: македонци), or Macedonian Bulgarians (Bulgarian: македонски българи), sometimes also referred to as Macedono-Bulgarians, Macedo-Bulgarians, or Bulgaro-Macedonians, are a regional, ethnographic group of ethnic Bulgarians, inhabiting or originating from the region of Macedonia. This is how the majority of Slavic-speaking population of Macedonia had been referred to by most of the national conscious minority among them and by outside observers, from the 10th until the early 20th century in a sense of a demonym at first, and later as an social class synonym mainly, and as ethnonym. Since 1913, the Macedonian Bulgarian population is largely concentrated in Pirin Macedonia but much is spread across the whole of Bulgaria and the diaspora.
