Here is a text describing how the Bulgarians tried to assimilate the Macedonians during their occupation of Macedonia in World War II.
This book was printed in Prilep 1961.
Here is a translation into English of the above text;
THE BULGARIAN AUTHORITES ATTEMPT TO FINALLY ASSIMILATE THE POPULATION.
Before the end of October 1941, the Bulgarian Municipal authorites sent Officials to the village from the Municipal and District capital – Prilep to conduct a census of the whole population.
The Officials had printed documents with them, were they entered the inhabitants of the village. The documents had all necissary paragraphs to enter the exact evidence (year of birth, place, gender, occupation, education) and finally there was a special paragraph which said “political affiliaton” and “nationality”.
The Officials put their hardest effort on the final paragraph in the census. They asked the people what nationality they are – Serbs or Bulgarians, but Macedonians were not at all mentioned.
Before the Officials began to assimilate the Macedonian population they held a short clarifying speech, in which they said that this people is Bulgarian “in origin” and needs to sign as that and further in the Bulgarian books as evidence.
That speech even more upset the villagers who told them that in this village there are no Serbs neither Bulgarians but only Macedonians. They asked the Officials if they could sign as Macedonian under the paragraph “nationality” in the census.
One of the Policemen tried to explaine to the villagers that Bulgarian and Macedonian are the same; that it has no relevance for the document, which is only a Record which will be in a archive.
The villagers forced the Officials and the Policemen to let them sign as “Macedonian” under the paragraph “nationality”.
Thus in the census Aleksandar S… entered him and his family as Macedonian, and after him followed the other villagers: Vanche S…, Vasil V…, Trajko M…, Dushan M…, Aleksa V…, Jovan S…, Tode V…, Nikola P…, Nikola Z…, and other villagers.
This open statement by the villagers against the Bulgarian assimilation made the Bulgarian Municipal authorities revolt and seek thru the District capital for a village leader from somewhere else to be sent to the village who is a Bulgarian and can help Bulgaria, but in the village of ….. there is noone who claims to be a pure Bulgarian. This was told to them by the villagers from their Municipal village leader Nikola K… on the conference where the new village leader Ilija L… from ….. was announced by a decree.
