THE CONCERT OF EUROPE AND THE POLICY OF INTERVENTION The defeat of Napoleon put an end to the attempt to unite Europe under the domination of a single State. The four great Powers—England, Russia, Austria and Prussia—who in 1814 assumed the title of allies, decided the fate of Europe. The allies determined to confine France within the frontiers of 1790 and to restore the dynasty of the Bourbons. With the restored king of France they signed the Treaty of Paris of May 3o, 1814, and announced their intention of establishing "a firm peace, based on a just equilibrium of strength between the Powers." The great Powers were united in their determination to keep the peace of Europe by maintaining the balance of power, and, as they alone possessed power, they agreed among themselves on the measures to be taken and imposed their decision on all the other States. The Congress of Vienna.—The Treaty of Paris restored to the allies all the territories that had been annexed to France since as well as those of the States created by Napoleon (Belgium, Holland, the left bank of the Rhine, Italy, Germany, the grand duchy of Warsaw) and also the kingdom of Saxony which the allies themselves had conquered in 1813. The allies summoned to Vienna a general congress of the representatives of all the States which had taken part in the war, to regulate the re-distribution of these territories (see VIENNA, CONGRESS oF) ; but in a secret article they reserved to themselves the right of determining between them the arrangements for the countries evacuated by France. They only referred to the congress the definitive settle ment of Germany and Poland.
The congress thus appeared as a sovereign assembly of the representatives of all Europe, who for the first time gave a body to European unity. But in truth the congress did little more than register the decisions of the allies. The representatives of small States were not even permitted to discuss them. The discussions over the territories of the king of Saxony became so violent that the concert of the allies was temporarily broken and agreement was only restored by a compromise which gave Prussia four non contiguous districts in place of Saxony. No question was discussed in the congress and all the arrangements were effected in the form of separate treaties between the different States and summed up under the title Final Act of the Congress of Vienna.
The deliberations had not yet reached their conclusion when Napoleon, who had escaped from Elba, restored the empire. The representatives assembled at Vienna declared, in the name of Europe, that Napoleon Bonaparte was "the enemy and disturber of the peace of the world," and undertook to preserve against all attack the order so happily re-established in Europe (March 24, 1815). Settlement in Europe.—The territories annexed by France in Italy and Germany were restored to their former and legitimate sovereigns, but none of the States which had been suppressed in Germany in 1803 were restored. The king of Bavaria received the Palatinate on the left bank of the Rhine; Prussia took the Polish province of Posen, received as indemnity three German provinces (Saxony, Westphalia and the Rhine Province), and acquired the remainder of Swedish Pomerania. Germany was formed into a confederation of sovereign States represented by a diet. In Italy the Genoese and Venetian republics were not restored, and Genoa was annexed to the kingdom of Sardinia. Austria re ceived the Milanais and Venice, which were united in a Lombard Venetian kingdom, and in Germany she received the ecclesiastical domain of Salzburg. Switzerland acquired the former bishopric of Basle and a piece of Savoy; Belgium and the kingdom of Holland were united into the kingdom of the Netherlands; and Norway, which was taken away from the king of Denmark, was given to the king of Sweden. Russia and England retained their conquests; England kept Malta and Heligoland, the protectorate of the Ionian Islands, and, outside Europe, the Dutch colonies in the Cape as well as Ceylon and Mauritius, while Russia retained Finland, which she conquered from the Swedes, and Bessarabia, which she had taken from Turkey. These arrangements were made secretly by the Governments, and without consulting the peoples of the countries concerned; they were based on the claims of legitimate princes and the denial of any right on the part of the peoples to determine their own destiny.
This system was intolerable, both to those who desired to set up a Constitution as a means to political liberty, and to those who sought to create States on a basis of nationality. These mal contents formed an opposition, henceforward called Liberal, and one which was later to be known as National. The Liberals and the Nationalists, in struggling against the same enemy, united in an attempt to destroy the system set up in 1815, and as all the European Governments were in agreement in seeking to main tain it, the opposition in each country had common interests with those in other countries and sought to act in concert with them. Since the Governments made it impossible for the oppositions to act in accordance with the law, they pursued illegal courses, by means of secret associations, murder and intrigue. (See CAR BONARI.) Their most efficacious method was to win over officers of the armies in order to compel the Government by means of military revolts to grant Constitutions.
For some years Metternich directed the policy of Europe. He took advantage of demonstrations on the part of German students and afterwards of four military revolts in 1820 in Spain, Por tugal, Naples and Sardinia to assemble congresses, which always met on the Austrian soil, at which the great Powers took steps for intervention in the internal affairs of other States. The con gress of Carlsbad in 1819 imposed on all the German States a system of police surveillance of the universities and the press; the congress of Troppau in 1820, which was subsequently trans ferred to Laibach, decided the intervention of the Austrian army in the Neapolitan kingdom ; while the congress of Verona in 1822 determined the French armed intervention that restored absolute monarchy in Spain. The three great autocratic Powers—Austria, Prussia, Russia—signed a declaration by declaring that any European State in a condition of internal revolution should remain excluded from the concert of Europe until law and order had been restored, and they reserved to themselves the right of using force to re-establish that order. Thus there came into inter national law the principle of intervention, and the Governments which were united in their common battle against the revolution sought not only to maintain by force the territorial settlement of 1815, but also the autocratic form of government. They estab lished themselves as the supreme political court of Europe for the control of international affairs. (See TROPPAU, CONGRESS OF ;
