The next three wars were fought without respect to the Concert of Europe. They arose from local causes and were soon determined without the aid of the Great Powers. They were the war of Austria and France over the liberation of Italy, 1859; the war between Prussia and Austria, 1866, in which Prussia overthrew the Austrian predominancy in Germany; and the Franco-Prussian war in 1870-1871, in which Prussia crushed France and made herself the head of the German Empire. In the first of these struggles no state could gain enough power to become a menace to the other states, since Italy was to be the recipient of all territory gained. Had the contest gone so far as to promise the vast enlargement of the power of France by reason of an alliance with enlarged Italy, interference might have resulted. In fact, the German states began to suspect such a result, and the realization of it was one of Napoleon’s reasons for withdrawing very unceremoniously from the war. Here we see, therefore, that the principle of concert was not entirely dead. The second and third wars were fought by a brilliantly organized state, Prussia, with whose successful armies no nation cared to make a trial of strength. In 1877 Russia made war on Turkey and proceeded with such energy that she soon forced the sultan to sign the treaty of San Stefano, altogether in favor of Russia. The particulars of the struggle belong to another chapter,[7] but here it is only necessary to point out that the Concert of Europe was now suddenly revived by the Great Powers, and Russia was forced to submit her well won victory to the Congress of Berlin, which scaled down the awards of San Stefano until Russia might well ask what was left of her victory. A similar thing happened in the Balkan War of 1912-1913. Here the parties concerned had fought their quarrel out to the end and had nearly expelled Turkey from Europe, dividing the spoils among themselves. Then in stepped the Great Powers, prescribing in a treaty at London the limits of gain to the successful contestants. They acted in the interest of peace; for Austria, watching the actions of Serbia and Greece, let it be known that she would not allow Serbia to have Albania, and the Powers interfered in order to prevent such action from kindling a great European war. [7] See below, p. 112. Thus in three notable wars, the Crimean War, the Russo-Turkish War, and the Balkan War, the action of the Great Powers was not to prevent war, but to neutralize its gains. So far did this principle go that writers were known to suggest that war would no longer be profitable to nations, since in a Concert of Europe the Great Powers would ever nullify the gains of the contestants.
