As a concession to the Yugoslav side, Bulgarian authorities agreed to the recognition of a distinct Macedonian ethnicity and language in part of their own population in the Bulgarian part of the geographic region of Macedonia. This was one of the conditions of the Bled Agreement, signed between Yugoslavia and Bulgaria on 1 August 1947. In November 1947, pressured by both the Yugoslavs and the Soviets, Bulgaria also signed a treaty of friendship with Yugoslavia.[13][14] The Bulgarian head of state Georgi Dimitrov was sympathetic to the Macedonian Question.[15] The Bulgarian Communist party was compelled once again to adapt its stance to Soviet interests in the Balkans.[14] The policies resulting from the agreement were reversed after the Tito–Stalin split in June 1948, when Bulgaria, being subordinated to Soviet interests, was forced to take a stance against Yugoslavia.[16]
