The ambition of Austria-Hungary played a large part at the Congress of Berlin. This nation had long looked upon the region that separated her from the Adriatic as a sphere through which she was justified in extending her power at the expense of Turkey, and she now felt that the time had come to realize her plans. If she waited, Russia would acquire such an influence as to forestall Austrian advancement. Her eyes were fixed on Bosnia and Herzegovina, for some time in revolt against Turkish misgovernment. Her influence was such that the congress gave her the right to occupy and administer the two provinces under the reservation of sovereignty to the sultan. The inhabitants, who were largely Slavic, were forced to accept the decision, although they did not relax their cherished hopes of independence. They were pawns thrown to Austria as a balance for the gains of Russia. The transaction only whetted the Austrian appetite for more and deepened the Serbian resentment for Austria.
Great Britain had her advantage out of the bargain also. She retained her position of paramount friend at Constantinople, justifying herself with the assurance that the sultan would carry out reforms in his empire. She seemed to think that the “Sick Man of Europe” would cure himself under her guidance and then defend himself against states that tried to oust him from his seat of power. To enable her to watch the bedside of her patient from a convenient position, as well as to safeguard the Suez Canal, Great Britain was given the right to occupy and administer the island of Cyprus under nominal authority of Turkey. To be perfectly fair we must admit that there is little moral difference between her acquisition of Cyprus and Austria’s gain in Bosnia and Herzegovina; and it is clear that in this case the Concert of Europe was a concert for the gain of selfish ends. It is also worth while to note that two of the Great Powers took no benefit from the agreement. France was slowly recovering from the war of 1870–1871 and was in no condition to fight, although in 1881 she established a protectorate over Tunis. The German Empire, newly founded and not yet fully adapted to the imperial system, was also in no condition to undertake a stiff encounter. There were many Germans who wished that their government should not allow the other states to get large gains of territory while Germany got nothing; but they yielded to Bismarck’s wise policy which held that it was not yet time for Germany to assume an aggressive position in the world. The impatience of the German patriots lost nothing through having to wait.
No treaty ends the march of time, and the Balkan situation continued to develop along the old lines. In 1881 Greece acquired Thessaly in accordance with a promise made to her at the Congress of Berlin. In 1885 East Rumelia declared herself united to Bulgaria, acting in defiance of the will of the Congress of Berlin. The Powers did not interfere for the same reason that they did not act when Wallachia and Moldavia united in 1862. To attempt to undo the union would have precipitated a general war. The Concert was stronger to prevent a given action than to correct it after it was done. Serbia, however, took the action of the two provinces as a menace and declared war against the new state of Bulgaria. She seemed about to throw herself on her adversary when she suddenly made peace, evidently feeling she was not strong enough to carry on the war alone.
Thenceforth the Powers showed that they did not mean to allow the Balkan states to profit by seizing parts of the decaying Turkish Empire. But for their restraint it seems that the Turk would have been expelled from Europe before the end of the nineteenth century.
Their intention was clearly manifested in regard to the island of Crete, whose population long suffered from Turkish oppression. In 1896 the island was in revolt and the sultan was forced to promise reforms. The assurance proved empty and in 1897 Greece interfered in behalf of Crete. In the war that followed the Greeks fought heroically but alone and were no match for Turkey in operations on land. They made peace without success, but through the instrumentality of the Great Powers the sultan agreed to allow Crete self-government under an elected assembly. The powers let it be known that they would not have the island annexed to Greece, which they did not mean to make a preponderating influence in the Balkans. Now appeared a great Cretan leader, Eleutherios Venezelos, whom his admirers call the Cavour of Greece. Under his influence the Cretan assembly voted the union of the island with Greece in 1905, but again the Powers interposed, insisting that the sovereignty of the sultan should not be abrogated. However, they permitted the Greek king to appoint a representative to rule the island as a Turkish fief, and Greek officers were allowed to train the Cretan soldiers and police. At last the Balkan war (1912–1913) brought the completion of union, the Great Powers yielding their assent.
The explanation of the conduct of the Powers in this incident is to be found in the delicate nature of the whole Balkan question. With Austria and Russia keenly aroused and each of the Balkan states anxiously looking for the moment when the rest of the sultan’s territory in Europe was to be divided between them, it was evident that a little thing could precipitate a serious conflict. It was in view of this phase of the situation that the Balkans were called “the tinder-box of Europe.”
It will be observed that while these things happened the Balkan states were developing steadily in national resources and spirit. Greece, Serbia, Bulgaria, and Rumania became vitally organized powers, it became more and more evident that they were no longer mere pawns in the diplomatic game, and the time was fast approaching when they would wish to take parts on their own initiative. So assertive were they becoming that it was certain that the time would soon come when the Great Powers would tire of the process of holding conferences to keep these states out of trouble. It is not an easy task to serve as custodian for a “tinder-box.”
A fair warning of this kind of danger occurred in 1908. For twenty-three years Bulgaria had remained undisturbed, giving herself to a rapid process of educational and industrial development, in both of which lines she had come under the influence of German methods. Suddenly she threw off her nominal Turkish sovereignty and declared herself an entirely independent state. At the same time, and evidently by agreement with the German Empire, Austria-Hungary announced that she would hold Bosnia-Herzegovina as an integral part of her empire, thus superseding the “occupation” that was authorized by the congress of Berlin, in 1878. Serbia took the matter as a great injury, but she could do nothing alone. Her natural ally was Russia, then recovering from the severe losses of the war against Japan. Had the tsar been ready for war it is doubtful if he would have drawn the sword in this instance; for a world war would have resulted, and the nations were not yet ready to think of such an undertaking. But Serbia nursed her wrongs and to Russia the sense of her shame grew as she thought how her weakness had been flaunted in the face of the world. The day came when the fire could no longer be smothered.
To understand Serbia’s feelings we must recall the national ideal by which her hopes had been formed for many years. Most of the people of Montenegro, Bosnia, Herzegovina, Novi-Bazar, and the northwestern corner of Macedonia were Serbs by blood. To unite them into a great Serbia had long been spoken of in Serbia as the “Great Idea.” When, therefore, Austria took definite possession of Bosnia-Herzegovina the “Great Idea” seemed defeated forever. Rage and despair possessed the Serbs wherever they lived, patriotic societies voiced the feeling of the people, and vengeance was plotted. Probably it was the feeling that this wide-spread hatred should be uprooted in the most thorough manner that prompted Austria to make the heavy conditions that were demanded as atonement for the crime of Sarajevo.
After Austria took the fateful step of 1908 Turkey still held the territory just north of the Bosphorus, organized as the province of Adrianople. She also had in Europe the provinces of Macedonia, Albania, and the sanjak of Novi-Bazar. To drive her out of these possessions was the object of the Balkan states. In 1911 Italy began a war against the sultan to gain Tripoli. The Balkan States seeing their enemy embarrassed, concluded that the hour of fate had come. They formed the Balkan League, made up of Greece, Bulgaria, Serbia, and Montenegro, and made ready for war. Their action alarmed the Great Powers, who brought the Concert of Europe to bear against the League. They gave the allies fair notice that they would not permit them to take any of the sultan’s territory in Europe, even though a war was won against him. The reply to this threat shows how weak the Concert had become. It was voiced by Montenegro, the smallest of the states, whose king immediately declared war and called on his allies to aid him in driving the pagan out of Europe. The call was accepted gladly and an ultimatum was sent to the sultan, who, relying on the promise of the Powers, defied his opponents.
