In 1820, the Neapolitan Carbonari once more took up arms, to wring a constitution from King Ferdinand I. They advanced against the capital from Nola under a military officer and the Abbot Minichini. They were joined by General Pepe and many officers and government officials, and the king took an oath to observe the Spanish constitution in Naples. The movement spread to Piedmont, and Victor Emmanuel resigned the throne in favor of his brother Charles Felix. It was only through the intervention of Austria. The Carbonari secretly continued their agitation against Austria and the governments in a friendly connection with it. They formed a Vendita. Pope Pius VII issued a general condemnation of the secret society of the Carbonari. The association lost its influence by degrees and was gradually absorbed into the new political organizations that sprang up in Italy; its members became affiliated especially with Mazzini's "Young Italy". From Italy, the organization was carried to France where it appeared as the Charbonnerie, which, was divided into verses. Members were especially numerous in Paris. The chief aim of the association in France also was political, namely, to obtain a constitution in which the conception of the sovereignty of the people could find expression. From Paris, the movement spread rapidly through the country, and it was the cause of several mutinies among the troops; it lost its importance after several conspirators were executed, especially as quarrels broke out among the leaders. The Charbonnerie took part in the Revolution, 1830; after the fall of the Bourbons, its influence rapidly declined. After this a Charbonnerie démocratique was formed among the French Republicans; after 1841, nothing more was heard of it. Carbonari was also to be found in Spain, but their numbers and importance were more limited than in the other Romance countries.
