The
Congress of Berlin (13 June – 13 July 1878) was a meeting of the representatives of the
Great Powers of the time (Russia, Great Britain, France, Austria-Hungary, Italy and Germany), four Balkan states (Greece, Serbia, Romania and Montenegro) and the Ottoman Empire, aiming at determining the territories of the states in the
Balkan peninsula following the
Russo-Turkish War of 1877–78. The Congress came to an end with the signing of the
Treaty of Berlin, which replaced the preliminary
Treaty of San Stefano signed three months earlier between
Russia and the
Ottoman Empire.
