In the year of the Congress of Carlsbad, the Propaganda menaced the kingdoms of Europe with a fresh revolution. Let us observe accurately their situation in 1820. Towards the south there was the insurrection of Spain and the Cortes, and the proclamation of a government more liberal than even that of England; at Naples, almost by a magical echo, the constitution was also proclaimed; from Naples the cry of liberty was heard in Piémont, and the king was deprived of his throne. In Paris the disturbances were so great that the government was exposed every evening to a change in its political system. This year of 1820 might be considered as the first edition of the stupendous event of July, which took place ten years later with all the fracas of an insurrection. Austria was particularly endangered by these revolutions, for the extremities of the kingdom of Naples and Piémont came in close contact with her Italian possessions. The people had declared themselves; the sovereigns then became aware of the danger, and roused themselves for their defence; congresses were held at Troppau and at Laybach, and Metternich, without hesitation, urged the adoption of powerful measures to quell the revolutionary spirit now manifested; he was so deeply convinced of their indispensable necessity, that he opposed every kind of delay, and only required the moral support of Prussia and Russia, declaring at once that an Austrian army was about to march into Italy and occupy Naples and Piémont. The Emperor Alexander, whose mind was full of the dread of secret societies and plots in Europe, lent his support to Metternich. There was but one single instance of opposition with regard to Piémont, and it is known from whence proceeded these objections. To such a degree has history been disfigured! It proceeded from the dignity of Louis XVIII., and the despatches of the Duc de Richelieu and M. Pasquier. The revolutionary spirit was breaking out in the streets of Paris in 1820, and the restored sovereign declared to Metternich, that if the Austrian army entered Piémont their occupation could not be of long continuance, as France could not allow of the Austrians upon the Alps.
