Despite some attempts to differentiate a Slavic Macedonian identity from the Bulgarian one since the end of the 19th century, and despite the nebulous national consciousness of the mass of the Slavic population, most researchers agree that the bulk of the Slavic population in the region had a Bulgarian national identity until the early 1940s, when the Bulgarian troops, occupying most of the area, were greeted as liberators. Pro-Bulgarian feelings among the local Slavic population prevailed in Greece and Yugoslavia. After the Second World War and Bulgarian withdrawal, on the base of the strong Macedonian regional identity a process of ethnogenesis started and distinct national Macedonian identity was formed. As a whole an appreciable Macedonian national consciousness prior to the 1940s did not exist. At that time even the political organization by the Slavic immigrants from the region of Macedonia, the Macedonian Patriotic Organization has also promoted the idea of Macedonian Slavs being Bulgarians. The nation-building process was politically motivated and later reinforced by strong Bulgarophobia and Yugoslavism. The new authorities began a policy of removing of any Bulgarian influence and creating a distinct Slavic consciousness that would inspire identification with Yugoslavia. With the proclamation of the new Socialist Republic of Macedonia, there were measures taken that would overcome the pro-Bulgarian feeling among the population. It has been claimed that from 1944 till the end of the 1940s people espousing a Bulgarian ethnic identity had been oppressed. According to Bulgarian sources more than 100,000 men were imprisoned and some 1,200 prominent Bulgarians were sentenced to death. In addition, the inconsistent policy towards the Macedonian Bulgarians followed by Communist Bulgaria at that time has thrown most independent observers ever since into a state of confusion, as to the real ethnicity of the population even in Bulgarian Macedonia. Practically as a consequence the rest of this people, with exception of Bulgaria proper, were eventually Macedonized or Hellenized. Nevertheless, people with Bulgarian consciousness or Bulgarophile sentiments still live in North Macedonia and Greece. During the last years the EU membership of Bulgaria has seen more than 50,000 Macedonians applying for Bulgarian citizenship. In order to obtain it they must sign a statement declaring they are Bulgarians by origin. More than 90,000 Macedonian nationals have already received Bulgarian citizenship. However, this phenomenon can not give precise information about how many Macedonian nationals consider themselves Bulgarians in ethnic sense, because it is widely believed that
