The origins of the term seem to be rooted in the 1910s, most of its early appearances were in the writings of Bulgarian authors. Since the mid-1940s the term has appeared on maps circulated first in Yugoslavia and especially after 1991 in the independent Republic of Macedonia which envisioned Greek Macedonia as part of a "Greater Macedonia", and is regarded in Greece as a non-recognition of current European borders, including the legitimacy of Greek sovereignty over the area. During the Greek Civil War, the Greek government referred to the usage as a "new term" only recently introduced by Josip Broz Tito in Yugoslavia, implying that it considered it part of the Yugoslav campaign of laying claim to Greek Macedonia. Tito's war-time representative to Yugoslav Macedonia, Svetozar Vukmanović-Tempo, is credited with promoting the usage of the regional names of the Macedonian region for irredentist purposes. In 1946, the Belgrade newspaper Borba published an article under the title "Aegean Macedonia", it was also published in Skopje's Nova Makedonija with a map of Yugoslav territorial claims against Greece. A month later, on September 22, the Premier of the People's Republic of Macedonia, Dimitar Vlahov, announced, "We openly declare that Greece has no rights whatsoever over Aegean Macedonia...". Vlahov then went on to publish, "The Problems of Aegean Macedonia", Belgrade, June 1947.
Post-WWII
By 1950, the term 'Aegean Macedonians' had been officially adopted by the Macedonian refugees in Skopje who began publishing the newspaper The Voice of the Aegeans; it is later found amongst diaspora communities. In Greece, the Slavic speakers of Greek Macedonia, were acknowledged as Slavomacedonians. A native of the region, former exile communist, teacher of Greek in Tashkent and local historian, Pavlos Koufis, says in Laografika Florinas kai Kastorias, that,
“ the KKE recognised that the Slavophone population was ethnic minority of Slavomacedonians]. This was a term, which the inhabitants of the region accepted with relief. Slavomacedonians = Slavs+Macedoninas. The first section of the term determined their origin and classified them in the great family of the Slavic peoples.”
The name "Aegean Macedonia" contains on the one hand a reference to a geographical area which, since Homeric times, is historically associated with the Greeks, but, as expressed above, there is also the experience that it is used by irredentist organizations in the Republic of North Macedonia and beyond who support a United Macedonia, contrary to the desires of the people living in the area. Writing in 1953, Lazar Mojsov seems surprised that the Greeks find the term "Aegean Macedonia" insulting, and uses it frequently, noting that "...Politisdidn't miss the opportunity to attack even the very term "Aegean Macedonia", stating that it was "coined by the communist propagandists". The term is currently used by some scholars, mostly contextualised, along with the sister terms Vardar Macedonia and Pirin Macedonia. The area of the Macedonian region that is part of Albania and Kosovo is often excluded. The term is used more frequently by ethnic Macedonians and has irredentist connotations.
