The Balkan Pact, or Balkan Entente, was a treaty signed by Greece, Romania, Turkey and Yugoslavia on 9 February 1934[1] in Athens,[2] aimed at maintaining the geopolitical status quo in the region after the end of World War I.

Other nations in the region that had been involved in related diplomacy refused to sign the document, including Italy, Albania, Bulgaria, Hungary and the Soviet Union.

The pact became effective on the day that it was signed and was registered in the League of Nations Treaty Series on 1 October 1934.

[3] The Balkan Pact helped to ensure peace between the signatory nations but failed to end regional intrigues.

With the 1940 Treaty of Craiova signed by Romania under Nazi Germany's pressure, and after the 1941 Axis invasions of Yugoslavia and Greece, the pact effectively ceased to exist and Turkey remained as its only signatory that had avoided any conflict during WWII, even after joining the Allies in 1945.
