Treaty of Berlin 1878: Reshaping European Borders

The Berlin Congress of 1878: A Diplomatic Landmark

The Treaty of Berlin was a resolution adopted by the Great Powers (German Empire, Austro-Hungarian Empire, France, Britain, Italy, Russian Empire, and the Ottoman Empire) at the Berlin Congress. This significant diplomatic event was held in Berlin, Germany, between June 13 and July 13, 1878. Key representatives included Otto von Bismarck (German Empire), Gyula Andrássy (Austro-Hungarian Empire), William Henry Waddington (France), and Benjamin Disraeli (Britain).

Context and Objectives of the Congress

The treaty resulted from intense pressure from the Great Powers, particularly the Austro-Hungarian Empire and Britain, to review the terms of the Treaty of San Stefano (March 3, 1878). The San Stefano treaty had been resolved very favorably to the interests of Russia and the new Slavic status quo in the Balkan Peninsula and the Eastern Mediterranean. The Berlin Congress also established German hegemony within the European balance of power system. Berlin was not merely the conference venue, and German Chancellor Bismarck was not only its president; the congress served as a crucial vehicle for German diplomacy to preserve the understanding among its allies (Russia and the Austro-Hungarian Empire).

Territorial Adjustments and New Recognitions

The new international order following the Treaty of Berlin brought significant territorial changes:

• The Greater Bulgaria, which had emerged from the Treaty of San Stefano, was divided into three parts:
  • The northern part was recognized as an independent state.
  • Southeastern Rumelia and much of Macedonia in the southwest remained under Ottoman influence.
• The independence of Romania, Serbia, and Montenegro was recognized, though their new borders were adjusted:
  • Romania lost Bessarabia to Russia but was compensated by the addition of Dobrudja.
  • Serbia and Montenegro were separated by a Muslim district, the Sanjak of Novi Pazar.
• Among the major powers:
  • The Russian Empire expanded its territory in Asia, acquiring Batum (now Batumi, Georgia), Kars, and Ardahan (both now in Turkey).
  • The Austro-Hungarian Empire was permitted to militarily occupy and provisionally administer the provinces of Bosnia and Herzegovina.

Long-Term Implications and Diplomatic Successes

The agreements reached at the conference vividly illustrate the ongoing process of the dismemberment of the Ottoman Empire in Europe. Crucially, these agreements did not fully meet the aspirations of nationalism among the Balkan Slavs. Despite this, the congress marked a success for German diplomacy in preserving the League of Three Emperors (formed by the German, Austro-Hungarian, and Russian Empires), even though it did not resolve the underlying Austro-Russian rivalry in the Balkans.
