The changes that have taken place in Europe in the last twenty years are of a most comprehensive character, and as strange as comprehensive; and their consequences are likely to be as remarkable as the changes themselves. In 1846 Russia was the first power of Europe, and at a great distance ahead of all other members of the Pentarchy. She retained the hegemony which she had acquired by the events of 1812-1814, and by the great display of military force she had made in 1815, when 160,000 of her troops were reviewed near Paris by the sovereigns and other leaders of the Grand Alliance there assembled after the second and final fall of the first Napoleon. Had Alexander I. reigned long, it is probable that his eccentricities--to call them by no harder name--would have operated to deprive Russia of her supremacy; but Nicholas, though he might never have raised his country so high as it was carried by his brother, was exactly the man to keep the power he had inherited,--and to keep it in the only way in which it was to be kept, namely, by increasing it. This he had done, and great success had waited on most of his undertakings, while in none had he encountered failure calculated to attract the world's attention. England had in some sense shared men's notice with Russia immediately after the settlement of Europe. The "crowning carnage, Waterloo," was considered her work; and, as the most decisive battle since Philippi, it gave to the victor in it an amount of consideration that was equal to that which Napoleon himself had possessed in 1812. But this consideration rapidly passed away, as England did nothing to maintain her influence on the Continent, while Russia was constantly busy there, and really governed it down to the French Revolution of 1830; and her power was not much weakened even by the fall of the elder Bourbons, with whom the Czar had entered into a treaty that had for one of its ends the cession to France of those very Rhenish provinces of which so much has been said in the course of the present year. Russia was victorious in her conflicts with the Persians and the Turks, and the battle of Navarino really had been fought in her interest,--blindly by the English, but intelligently by the French, who were willing that she should plant the double-headed eagle on the Bosporus, provided the lilies should be planted on the Rhine. If the fall of the Bourbons in France, and the fall of the Tories in England, weakened Russia's influence in Western Europe, those events had the effect of drawing Austria and Prussia nearer to her, and of reviving something of the spirit of the Holy Alliance, which had lost much of its strength from the early death of Alexander. Russia had her own way in almost every respect; and in 1846 Nicholas was almost as powerful a ruler as Napoleon had been a generation earlier, with the additional advantage of being a legitimate sovereign, who could not be destroyed through the efforts of any coalition.
