Montenegro aside, the first group to become a state was Serbia, whose hardy mountain inhabitants rose in revolt in 1804. A number of brave leaders appeared and valley by valley the Turks were forced out of the country. The Serbs were practically independent for a time, but the sultan did not acquiesce in their freedom, and the constant preparedness that was necessary to repel any attack he might launch was a source of much expense and anxiety to the people.

In 1821 the Greeks, also under the domination of Turkey, rose in revolt. Great sympathy was aroused in the rest of Europe and in spite of the disposition of the Great Powers to allow Turkey a free hand to preserve her territory intact, lest one of them gain over-balancing territory, public opinion forced them to intervene. The first to show sympathy was Russia, who had an interest in making herself the protector of the Christians in Turkey. The other powers resented her assistance to the Greeks, and finally Great Britain and France united in a project of intervention, sending a joint fleet to the Mediterranean which destroyed the Turkish fleet at Navarino in 1827. The stubborn sultan remained unyielding, and in 1828 Russia entered the war openly, having come to an agreement with the other Powers. She sent an army across the border which carried all before it, and the sultan was forced to make the treaty of Adrianople, in which Turkey recognized the independence of Greece and acknowledged Serbia as an autonomous state under Turkish suzerainty. At the same time Wallachia and Moldavia, where Rumans lived, were recognized as independent under a Russian protectorate. Thus one sovereign and three dependent but locally autonomous states stood forth out of the confused and misgoverned Christian area of Turkey in Europe.

The rest of the region, occupied by Bulgars and Albanians, with Bosnia and Herzegovina, claimed by the Serbs as legitimate parts of their national habitat, remained in an unredeemed condition and were governed by agents appointed by the sultan. Montenegro retained her position of practical independence, which Turkey had been forced to acknowledge in 1799. These arrangements were confirmed in a more formal treaty in 1832.

The successes of this period quickened the spirit of nationality in the Balkans. Just as the Greeks were swept by a wave of enthusiasm for their classical culture and sought to revive the language and ideals of the remote past, so the Balkan peoples set out to revive their ancient culture, long obscured by the shadow of Turkish masters. Serbs, Rumans, and Bulgars made grammars of their own languages, gathered up what was preserved of their ancient literatures and traditions, taught their children to revere the national heroes, and sought in many other ways to stimulate the spirit of nationality. The Slavic portion turned to Russia for support, whom they called their “big brother,” while the Rumans cultivated an appreciation of Italy and France, whom they considered kindred descendants of the ancient Romans. To their national hopes in these things was added the desire for religious independence. They disliked being under the ecclesiastical authority of the Patriarch of Constantinople, who was appointed by the sultan, and looked forward to a time when they might have exarchs of their own, with jurisdiction not limited by the Patriarch.

In 1854 Russia was ready for another advance in the region of the Balkans, hoping to gain at last what Peter the Great had declared was essential to her progress, a window looking out on the Mediterranean. Great Britain and France came to the help of the sultan and the Crimean War followed. After a hard struggle it ended in Russia’s defeat, and at the Conference of Paris, 1856, the affairs of the Balkans were again up for settlement, but this time the victory leaned to the side of the Turk, although it was modified by the restraining hand of his two allies. The purport of the treaty was to reduce the power of Russia, and in doing so the aspirations of the Balkans states were checked. The protectorate the tsar had established over Wallachia and Moldavia was destroyed, and Bulgars, who had expected independence, remained under the rule of the sultan, while Greece, who had desired a large portion of Macedonia, was forced to continue in her old boundaries. This crisis was not the last in which the vexed Balkan question, seemingly near solution, was made to give way before the complicated problems of the general European situation. Looking backward we may well say that if Russia had secured her wish, expelled the Turk from Constantinople and liberated the Balkan states, the fortunes of France would not have been lessened, and Great Britain, safe through her supremacy at sea, would not have lost any of the strength she had in India. At the same time the sore spot of European relations would have been healed, and we should probably have had no war in 1914.

Wallachia and Moldavia were of the same stock and wished to unite as one kingdom. They made their desires known in the negotiations that resulted in the Treaty of Paris, but the Powers did not mean to create a large state on the borders of Russia which might prove a bulwark of influence for the tsar, and accordingly they denied the request. The two states found a way to accomplish their desire, soon after the conference at Paris adjourned. Meeting to select rulers each chose Alexander John Cuza simultaneously, and after hesitating two years the Powers acknowledged him as king. Thus was formed the united kingdom of Rumania; and its formation illustrated a weak point in the Concert of Europe. However much the Powers might interfere to prevent the consummation of an act they considered dangerous, they would think twice before trying to punish a Balkan state, since in doing so they might set off an explosion in the very system they were working to keep peaceful. Rumania understood this phase of the matter and took her chances. Her firm course had its reward.

The influence of Great Britain was now paramount at Constantinople. The sultan was satisfied with his ally, since he knew that of all the Powers he had least to fear from this state, which had no territories in that part of the Mediterranean and was committed to the preservation of his rule as a means of keeping Russia away from the Bosphorus. To justify herself for defending the Turk, Great Britain gave the world assurances that the sultan was about to become good. Under her insistance a series of reforms was announced, but they did not go far in the realization. Some of the promises referred to the government of the Balkans, but they were as fruitless as the others. Meanwhile French and British merchants found large profits in Turkish trade.

The tsar was humiliated by his loss of influence in the Southeast, and in 1877 he began another war against Turkey. He thought the time favorable for such action. Impeded for a while at Plevna, in Bulgaria, he at last swept the enemy before him and took Adrianople on January 16, 1878. His successes created great enthusiasm among the Serbs, Bulgars, and Rumans, who flocked to his victorious standard. The panic-stricken sultan sued for peace and at San Stefano signed a treaty which granted all that was demanded of him. Serbia, Montenegro, and Rumania were recognized as completely independent, Bulgaria as an autonomous tributary province, and Bosnia and Herzegovina were assured of important administrative reforms. Russia was awarded some territory not strictly in the Balkans, but her greatest gain was the prestige she now had as liberator of Christian states.

The treaty of San Stefano alarmed Great Britain and Austria, both of whom felt that they had major interests at stake. They got a congress of the Great Powers to meet at Berlin, 1878, which revised the treaty in what they were pleased to call the interest of European peace. Complete independence was announced for Serbia, Rumania, and Montenegro, and the sultan accepted the fact of their perfect sovereignty. By the treaty of San Stefano Bulgaria was to include Macedon and eastern Rumelia, making one great buffer province between the Turkish and the Christian states. The three parts were now left distinct, Bulgaria proper being autonomous but under Turkish suzerainty, and the other two less independent.

To create a “Big Bulgaria” as a bulwark against Turkey had been Russia’s chief hope in the war. Her initial success awakened enthusiasm in all the Balkan people, and the results were expressed in the way in which they rallied to her aid. At last, said the onlookers, an opportunity had come to found a strong Balkan confederacy which would play an important part in the development of the Near East. The hand of Russia seemed strong enough to hold these nascent states to one policy, allay their incipient jealousies, and bring them to a great common ideal. If such a course could have been adopted the future of Europe would have been profoundly altered. It was defeated by that Concert of Europe which was supposed to exist in order that the world might be spared the burden of war. It was really prevented through the operation of the forces of national selfishness, safely esconced in the system which we have called the Concert of Europe.
