三帝同盟
Italy was dissatisfied with the results of the Congress, and the tensions between Greece and the Ottoman Empire were left unresolved. Bosnia-Herzegovina would also prove to be problematic for the Austro-Hungarian Empire in later decades. The League of the Three Emperors, established in 1873, was destroyed since Russia saw lack of German support on the issue of Bulgaria's full independence as a breach of loyalty and the alliance. The border between Greece and Turkey was not resolved. In 1881, after protracted negotiations, a compromise border was accepted after a naval demonstration of the great powers had resulted in the cession of Thessaly and the Arta Prefecture to Greece.
