During the early years of the French Revolution he issued several pamphlets against Mirabeau, who returned his ill-will with interest, calling him 'the ignorant and bombastic M. Linguet, advocate of Neros, sultans and viziers'. On his return to Paris in 1791 he defended the rights of the Haitian revolutionaries before the National Assembly. His last work was a defense of Louis XVI. He retired to Marnes-la-Coquette near Ville d'Avray to escape the Reign of Terror, but was sought out and summarily condemned to death for having flattered the despots of Vienna and London. He was guillotined in Paris on 27 June 1794.
