The Congress of the Powers met at Berlin on June 13, 1878, under the presidency of Prince Bismarck. It was the most important gathering of the kind since the Congress of Vienna in 1815. The Great Powers were represented by their leading statesmen. England, by Lord Beaconsfield and Lord Salisbury; Russia, by Prince Gortchakoff and Count Schouvaloff; France, by its Prime Minister, Waddington; Italy, by Count Corti, its Foreign Minister; Austria, by Count Andrassy. The Porte, apparently, was unable to find a competent Turk for the purpose. It was represented by Karatheodori, a Greek, and by Mehemet Ali, a renegade German. Germany, it need not be said, was represented by Bismarck, who acted as the ‘honest broker.’ Although apparently invested with unlimited authority to deal with all questions arising out of the treaty of San Stefano, the Congress found that its hands were practically tied behind its back by the agreement between England and Russia. It had no other option than to cut down the big Bulgaria under the tripartite scheme already described, which was the essence of the Anglo-Russian agreement. As regards the artificially created province of Eastern Roumelia, Lord Beaconsfield, who throughout the proceedings of the Congress championed the Turkish cause, insisted that the Porte was to have the right to maintain garrisons in its frontier fortresses. He threatened to break up the Congress if this was not conceded. Russia, though strongly opposed to this, ultimately gave way. This was a triumph for Beaconsfield, the value of which we can now appreciate, with the knowledge that no advantage was ever taken by the Porte of this permission to garrison Eastern Roumelia. The most important point on which the Congress effected a change in the treaty of San Stefano was in respect of Bosnia and Herzegovina. At the instance of Bismarck, these two provinces, instead of being endowed with autonomous government, were handed over to Austria for occupation and administration, while remaining nominally a part of the Turkish Empire. Montenegro was to lose half of the territory conceded to it at San Stefano.[44] The claims of Greece for a definite extension of its territory were championed by the representative of France, but were opposed by Lord Beaconsfield. The Congress contented itself with a recommendation to the Sultan that the boundaries of Greece should be extended so as to include Thessaly and a part of Epirus. Organic reforms of administration and law were to be carried out by the Porte in the European provinces of the Empire on the recommendation of a Commission to be appointed by the Great Powers.
