the Yugoslav communists proclaimed as their aim the unification of Macedonia's three regions (Yugoslav, Greek and Bulgarian), thus attracting the Macedonian nationalists. During the following operations of the National Liberation War of Macedonia the Macedonian Communist combatants developed aspirations over the geographic region of Macedonia that continued after 1944 during the Greek Civil War. The Bled agreement (1947) signed by the communist leaders Georgi Dimitrov and Josip Broz Tito also foresaw the unification of Yugoslav and Bulgarian Macedonia. It was also the first time that Bulgaria recognized ethnic Macedonians and the Macedonian language. After the Tito–Stalin split in 1948 and the death of Dimitrov in 1949, in the same year the communists lost the Civil War in Greece. That put to an end the practical application of the concept. After the breakup of Yugoslavia Since 1989, ethnic Macedonian nationalists have called for a "United Macedonia", stating that "Solun (Thessaloniki) is ours" and "We fight for a United Macedonia". Several maps depicting "United Macedonia" as an independent country, stating irredentist claims of the Macedonian nationalists against both Greek and Bulgarian territory, circulated since the late 1980s and the beginning of the 1990s.

The Macedonian nationalists break down the region of Macedonia as follows: Vardar Macedonia (Вардарска Македонија) which includes: the territory of North Macedonia; Gora (Гора), small portions of southern Kosovo and eastern Albania Prohor Pčinski (Прохор Пчински), southern Serbia; and Greek Macedonia (or "Aegean Macedonia", "Егејска Македонија"), northern Greece; Blagoevgrad Province (or "Pirin Macedonia", "Пиринска Македонија"), southwestern Bulgaria; and Mala Prespa and Golo Brdo (Мала Преспа и Голо Брдо), Albania. Macedonian nationalists describe the above areas as the unliberated parts of Macedonia and they claim that the majority of the population in those territories are oppressed ethnic Macedonians. In the cases of Bulgaria and Albania, it is said that they are undercounted in the censuses (In Albania, there are officially 5,000 ethnic Macedonians, whereas Macedonians nationalists claim the figures are more like 120,000-350,000. In Bulgaria, there are officially 1,600 ethnic Macedonians, whereas Macedonian nationalists claim 200,000). In Greece, there is a Slavic-speaking minority with various self-identifications (Macedonian, Greek, Bulgarian), estimated by Ethnologue and the Greek Helsinki Monitor as being between 100,000-200,000 (according to the Greek Helsinki Monitor only an estimated 10,000-30,000 have an ethnic Macedonian national identity).
