After the end of World War I Greece perceived Belgrade as a powerful neighbor with potentially hegemonic tendencies in the Balkans. Yugoslav ability to attract support from the great powers, mainly France, created concerns in Athens that Yugoslavia will pressure Greece on the status of Slavic speakers of Greek Macedonia and potentially even the Port of Thessaloniki. Greece was concerned that close ethnic, linguistic and religious links between Yugoslavia and Bulgaria will lead to an alliance. This alliance however did not materialize as Yugoslavia was a status quo state which sought to consolidate success of the South Slavic unification movement while Bulgaria was revisionist state. Similarly to the situation with Kingdom of Serbia in the Second Balkan War, Yugoslavia joined forces with Kingdom of Greece, Kingdom of Romania and Turkey in establishing the Balkan Pact aimed at maintaining the geopolitical status quo. Compared to emotional tensity which Macedonian question enjoyed among Bulgarian elites, dominant Serb (and to a lesser extent Croat and Slovene) elites in the Kingdom of Yugoslavia expressed lesser interest in the issue. Kingdom of Serbia reoriented its expansionist interest towards south (regions with small number of ethnic Serbs) only after the Bosnian Crisis and in fear of encirclement between more powerful Austria-Hungary and Bulgaria. In Yugoslav period southern part of the country was known as the Vardar Banovina.
