Aegean 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" (August 26, 1946) 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 (speech in Nova Makedonija, on September 26, 1946), 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.
