The territorial arrangements thus effected were for half a century the basis of the states system of Europe, and the treaties in which they were defined the charter of international relations. It was in central Europe, Territorial adjustments of the Vienna treaties. where Napoleon’s policy had most profoundly affected the pre-revolutionary system, that the greatest changes were made. No attempt, indeed, was made to restore the Holy Roman Empire, in spite of the protest of the pope against the failure to re-establish “the centre of political unity”; but the Confederation of the Rhine having come to an end, Germany was reconstituted as a confederation of sovereign states, in which all the former members of the Empire which had survived the revolutionary epoch found a place (see [Germany]). Austria, in virtue of the imperial tradition of the house of Habsburg, received the presidency of the federal diet; but the bulk of her territories lay outside the frontiers of the Confederation, and the non-German character of the Habsburg monarchy was accentuated by the other arrangements at the congress. In Italy Lombardo-Venetia was erected into a kingdom under the Austrian crown; while the dynastic settlements in the other Italian states tended to make Austrian influence supreme in the peninsula (see [Italy]). In return for this, Austria surrendered her claim to her former possessions in the Low Countries, which were annexed to the crown of Holland, so as to form, under the title of the United Netherlands, an efficient barrier to French aggression northwards. The function of defender of Germany on the Rhine frontier which Austria thus abandoned was assigned to Prussia, an arrangement pregnant with momentous issues. In compensation for her disappointment in the matter of Saxony, half of which was ultimately restored to the dynasty of Wettin, she received a large accession of territory in the Rhine provinces, carved partly out of the suppressed kingdom of Westphalia, partly out of the former ecclesiastical states, and comprising the imperial city of Aix-la-Chapelle and the former electorate of Cologne. To Prussia also was conceded the right to garrison the federal fortress of Luxemburg.
Of the other German states, Bavaria, which alone was sufficiently powerful to be of any great importance in the general affairs of Europe, reaped the reward of her timely defection from the cause of her protector Napoleon. She had, indeed, to restore to Austria the territories annexed to her at the expense of the Habsburg monarchy by the French emperor: Tirol, the Quarters of the Inn and of the Hausruck, and part of Salzburg. But she received ample compensation elsewhere, notably the former Bavarian Palatinate with a strip of territory to connect it with Bavaria proper. The right to garrison the federal fortress of Mainz was also ultimately conceded to her. Bavaria was thus placed in a position to continue her traditional policy of aiming at the position of a European great power and holding the balance between Austria and Prussia (see [Bavaria]: History). The two other German states whose elevation to kingdoms had symbolized a similar ambition, Saxony and Württemberg, were henceforth relegated to a position of third-rate importance; Saxony depended for her very existence on the rivalry of her more powerful neighbours: Württemberg protested in vain against the dictatorship of the great powers to which she was forced to submit. Finally, the electorate of Hanover, partly out of compliment to the king of Great Britain, partly because with the abolition of the Holy Empire the title elector had fallen obsolete, was elevated to a kingdom. The request of the elector of Hesse for a similar concession in his case was refused by the powers assembled at Aix-la-Chapelle in 1818.
Of great importance were the changes effected in the north and east of Europe. The affairs of the Ottoman empire, which the treaty of Bucharest (1812) between Russia and Turkey had left in a very unsatisfactory condition, were not dealt with by the congress, in spite of the efforts of Great Britain to bring them into discussion. But the concessions made to the emperor Alexander elsewhere represented a notable advance in the European position of Russia. The possession of Finland, conquered from the Swedes in 1808, was confirmed to her; and, above all, the erection of the former grand-duchy of Warsaw into a constitutional kingdom of Poland under the Russian crown not only thrust the Muscovite power like a wedge into the heart of Germany, but seemed to threaten the Polish possessions of Austria and Prussia by setting up a quasi-independent Poland as a centre of attraction to the scattered elements of the Polish nation; though in the sequel the establishment of the city of Cracow and its territory as an independent republic, to avoid the difficult question of its assignment elsewhere, proved a more fruitful source of nationalist unrest. In the north the settlement confirmed by the congress marked the definite withdrawal of the Scandinavian Powers from any active influence on the affairs of the continent. Alone of the parvenu monarchs of the Napoleonic age Bernadotte retained the crown of Sweden, to which, by the treaty of Kiel, that of Norway had been added. On the other hand, by the cession of Swedish Pomerania to Prussia, Sweden finally withdrew from the southern shores of the Baltic. The Scandinavian states ceased henceforth to play any determining part in European politics. In the south, on the other hand, the restoration of Savoy and Piedmont to Victor Emmanuel I., king of Sardinia, and the incorporation in his dominions of the territories of the former republic of Genoa, were factors pregnant with mighty issues. The object of this increase of the power of the house of Savoy was but to erect a barrier against any possible renewal of French aggression in Italy; in effect it established the nucleus of the power which was to struggle successfully with Austria for the hegemony of Italy.
The gains of Great Britain in Europe were comparatively small, though by no means unimportant. By the retention of Malta she secured her power in the Mediterranean, and this was further increased by the treaty of Paris (November 5, 1815), by which the powers recognized her protectorate over the Ionian Islands. (See [Vienna, Congress of].)
But for the episode of the Hundred Days, France would have emerged from the congress with recovered prestige and mistress of at least some of the territorial gains of the revolutionary wars; though Napoleon had thrown away, during The powers and France. the negotiations at Châtillon, the chance of preserving for her her “natural frontiers” of the Rhine, the Alps and the Pyrenees. After Napoleon’s second downfall she was in serious danger of dismemberment, for which the German powers clamoured as essential to their safety. That Louis XVIII. continued to rule over the territories “handed down to him by his ancestors” was due to the magnanimity, or policy, of the emperor Alexander I. (q.v.), and the commonsense of Castlereagh and Wellington, who saw well that the “just equilibrium,” which it was their object to establish, could not be secured if France were unduly weakened, and that peace could never be preserved if the French people were left to smart under a sense of permanent injury. By the second peace of Paris, signed on the 20th of November 1815, France retained her traditional boundaries. The unsatisfied ambition to secure her “national frontiers” was to bear troublesome fruit later.
That the treaties embodied in the Final Act of Vienna represented a settlement of all outstanding questions was believed by nobody. They had been negotiated for weary months in an atmosphere of diplomatic and feminine intrigue; they had been concluded in a hurry, under the influence of the panic caused by Napoleon’s return from Elba. To Friedrich von Gentz they were at best but “partial arrangements,” useful as forming an authoritative basis for the establishment of a more complete and satisfactory system. The history of the international politics of Europe for the years immediately succeeding the congress of Vienna is that of the attempt to establish such a system.
After a quarter of a century of almost ceaseless wars, what Europe needed above all things was peace and time to recuperate. This conviction was common to all the powers who had inherited Napoleon’s dictatorship in Europe; but on Treaty of Nov. 20, 1815, and the Concert of Europe. the question of the method by which peace should be secured, and the principles which should guide their action, a fateful divergence of view soon became apparent within their councils. All were agreed that France still represented the storm centre of Europe; and a second treaty, signed on the 20th of November 1815, renewed the provisions of the treaty of Chaumont, in view of any fresh outburst of the French revolutionary spirit. But the new treaty went further. By its 6th article it was declared that “in order to consolidate the intimate tie that unites the four sovereigns for the happiness of the world, the High Contracting Powers have agreed to renew at fixed intervals ... meetings consecrated to great common objects and to the examination of such measures as at each of these epochs shall be judged most salutary for the peace and prosperity of the nations and for the maintenance of the peace of Europe.” This was the formal charter of the concert of the great powers by which for the next seven years Europe was governed, a concert to which the name “Holy Alliance” has been commonly The Holy Alliance. but erroneously applied. The Holy Alliance, drawn up by the emperor Alexander I., and signed by him, the emperor Francis, and King Frederick William III. of Prussia on the 26th of September 1815, represented a different and conflicting ideal. Actually it was not a treaty at all, but at best a declaration of principles to which any Christian could subscribe, at worst—to quote Castlereagh—“a piece of sublime mysticism and nonsense” from the political point of view (see [Holy Alliance]). It gained its sole political importance from the persistent efforts of the tsar and his ministers to replace the committee of the great powers, established by the treaty of the 20th of November, by a “Universal Union” of all the powers, great and small, who had signed the Holy Alliance, and thus to establish that “Confederation of Europe” of which the autocratic idealist had borrowed the conception from the theorists of the 18th century (see [Alexander I.], emperor of Russia). It was clear from the first that any attempt to set up such a central government of Europe England and the Concert. under a “universal guarantee” would imperil the independence of the sovereign states; and from the first Great Britain, represented by Castlereagh, protested against it. She would consent to take common action on the basis of the treaties she had actually signed, consulting with her allies on each case as it arose; but to vague and general engagements she refused to commit herself. The attitude of Austria and Prussia was from the outset less clear. Metternich was torn between dread of revolution and dread of Russia; the Holy Alliance, though essentially “verbiage,” might be useful in holding the imperial Jacobin in check; the “universal guarantee” could not but be discouraging to the “sects”; on the other hand, the extreme willingness of the tsar to march 200,000 Russians for any “European” purpose in any direction convenient or inconvenient to Austria, was—to say the least—disconcerting. Frederick William III., on the other hand, though he too had signed the Holy Alliance with reluctance, in moments of panic saw in the “universal guarantee” his best defence against the renewed attack by France which was his nightmare. In effect, owing to the firm attitude of Castlereagh at the congress of Aix-la-Chapelle, “the transparent soul of the Holy Alliance” never received a body, though attempts were subsequently made at the congresses of Troppau, Laibach and Verona to apply some of its supposed principles—attempts that led to the definitive breach of Great Britain with the Alliance.
The highwater-mark of the activity of the Allies as a central government for Europe was reached at the congress of Aix-la-Chapelle (q.v.) in 1818. France was now admitted to the Alliance, the objects of which were reaffirmed by a Congress of Aix-la-Chappell, 1818 public declaration to which she adhered; but at the same time a secret treaty renewed the compact of Chaumont between the four other powers. Certain questions outstanding from the congress of Vienna were referred for settlement to a ministerial conference to meet at Frankfort in the following year. The treaty which was the result of this conference was signed on the 20th of July 1819. The bulk of it was concerned with territorial settlements in Germany: between Austria and Bavaria, and Bavaria and Baden; but some of the articles arranged for the cession of the border fortresses Philippeville and Mariembourg to the Netherlands, defined the frontiers of Savoy, and settled the reversion of the Italian duchies held by the empress Marie Louise.
Meanwhile the balance of forces within the European concert had shown a tendency to shift. At the outset the restless activity of the emperor Alexander, his incalculable idealism, and his hardly veiled ambitions had drawn Alexander I. of Russia and Metternich. Austria and Great Britain together in common suspicion of an influence that threatened to be little less disturbing to the world’s peace than that of Napoleon. But at Aix Metternich had begun to realize that, in the long-run, the system of repression which he held to be essential to the stability of the European, and above all of the Austrian, polity would receive little effective aid from Great Britain, fettered as she was by constitutional forms; while Alexander, alarmed at the discovery of revolutionary plots against his person, had already shown gratifying signs of repentance. The “Jacobin” propaganda of the tsar’s agents continued, it is true, especially in Italy; and, in spite of the murder of the dramatist Kotzebue, as a Russian emissary, by the fanatical “Bursche” Karl Sand, Alexander joined with Castlereagh in protesting against the reactionary policy embodied in the Carlsbad Decrees of October 1819. But the murder of the duke of Berri on the 13th of February 1820 completed the Russian autocrat’s “conversion.” At the congress of Troppau, which met in the autumn of the same year, he was a “changed man,” committed henceforth heart and soul to Metternich and his policy. The outcome of this new Congress and protocol of Troppau, 1820. understanding was the famous Troppau Protocol, published to the world on the 19th of November 1820, and signed by Austria, Prussia and Russia. The immediate occasion of this manifesto was the military insurrection, under General Pepe, at Naples, by which the Spanish constitution of 1812 had been forced on the king (see [Naples]: History). But the protocol embodied a general principle involving issues infinitely more important than any arising out of this particular question. “States which have undergone a change of government due to revolution,” it declared, “the results of which threaten other states, ipso facto cease to be members of the European alliance, and remain excluded from it till their situation gives guarantees for legal order and stability. If, owing to such alterations, immediate danger threatens other states, the powers bind themselves, by peaceful means, or if need be by arms, to bring back the guilty state into the bosom of the Great Alliance.”
This was, in effect, an attempt to apply the principle of the Carlsbad Decrees to all the world; and, had the attempt succeeded, all Europe would have been turned into a confederation on the model of that of Germany; for a political alliance, charged with the safeguarding of the territorial settlement defined by treaty, would have been substituted a central diet of the great powers, armed with undefined authority; and the sovereign independence of the nations would have been at an end. To any such principle, and therefore to the protocol in which it was embodied, Great Britain offered an uncompromising opposition. In vain Metternich urged upon Castlereagh that the protocol was but the logical conclusion drawn from premises to which he was already committed; for, if the alliance was to be effective in maintaining peace, it must interfere wherever and whenever peace should be threatened, and therefore to crush internal revolutions which could not but have an external result. The logic was perfect; the proposition that on which every “project of peace” must eventually break. Castlereagh’s reply was, in brief, that Great Britain could never admit a principle which she would not in any circumstances allow to be applied in her own case.
