Imperial responsibilities entail the protection of friendly tribes against hostile attack in the outlying parts of the Empire. Punitive expeditions become necessary and annexation is found to be the best method of securing law and order. RUSSO-TURKISH WAR 1877–1878 Belligerents: Russia. Turkey. Cause: The persecution and oppression of Christians in the Ottoman Empire led to a revolt in Herzegovina in 1875. Andrassy, on behalf of Austria, presented a Note to the Turkish Government demanding reforms, and this was followed by the Berlin Memorandum, signed by Germany, France, Austria, Russia, and Italy. Great Britain alone stood out. The Bulgarian massacres in June 1876 caused a great sensation in England, and were followed by a declaration of war by Servia and Montenegro against Turkey. Great Britain, always mistrusting Russian designs, called a Conference. The demands of the Conference were rejected by Turkey in January 1877. The Sultan protested against the encroachment of the Powers on his inviolable rights. Occasion: The London Protocol of March 1877, signed by Great Britain and Russia and agreed to by the other Powers, called for reforms and expressed the intention of the Powers to safeguard the Christian population. This was also rejected by the Turks, and Russia declared war on April 24, 1877. Course of the War: The Russian army crossed the Danube. Plevna fell in December 1877. The Russians entered Adrianople, January 1878. The advance of the Russian army towards Gallipoli was followed by the dispatch of the British fleet to Constantinople and brought Russia and Great Britain within a hair’s-breadth of war. This, however, was avoided and peace negotiations began. Political Result: _Treaty of San Stefano_, March 3, 1878. The independence of Servia, Montenegro, and Roumania was recognized. Bulgaria was made an autonomous principality with frontiers including the greater part of European Turkey; the Dobrudja and certain districts in Asia Minor were ceded to Russia. Great Britain objected strongly to this treaty, and proposed a Congress at Berlin. While the chances of the Congress hung in the balance, Great Britain made warlike preparations, but the Congress was finally agreed to. _Treaty of Berlin_, July 13, 1878. Bulgaria’s frontier was confined to the country north of the Balkans. Bosnia and Herzegovina were handed over to Austria: the territory given to Serbia and Montenegro was further restricted: Thessaly and part of Epirus were ceded to Greece. By a secret convention Great Britain engaged to protect Turkey against further aggression of Russia in Asia. In return the Porte assigned Cyprus to be occupied and administered by England. Lord Beaconsfield was the British Plenipotentiary at the Peace Congress and returned declaring he had secured “peace with honour.” Remarks:
