Filippo Buonarotti, a French revolutionist, a descendant of Miehel Angelo, born in Pisa, Nov. 11,1761, died in Paris, Sept. 15,1837. He became a favorite of the grand duke of Tuscany, but was expelled from Italy, and afterward from Corsica, on account of his revolutionary publications. He then went to Sardinia, where, as in Corsica, he advocated annexation to France, and the Sardinians made him draw up for them a liberal constitution. In 1793 he procured the annexation of the small Corsican island of St. Pierre to the French republic, and the convention conferred upon him French citizenship. On the fall of Robespierre, with whom he was intimate, he was arrested, and after his release he conspired for the reestablishment of the constitution of 1793, and became founder and president of a revolutionary society called the Pantheon. This being dissolved by the government, he joined the conspiracy of Babeuf, and was sentenced to transportation (1797); but he was ultimately allowed to remain in France under surveillance.

In 1806 he went to Geneva, and became a teacher; but in 1815 he was expelled from that city, and went to Brussels, where he published in 1828 his Histoire de la conspiration pour Vegalite, dite de Babeuf (new ed., 1850). After the revolution of 1830 he taught music in Paris under the name of Remond. In 1835 he was one of the defendants in the trial of the insurrectionists of April, 1834.
