[2] Elected to the National Convention in September 1792, he developed moderate, even reactionary views, becoming one of the fiercest opponents of Montagnards - although he never wavered in his support for the French Republic.
[1] His daily attacks on The Mountain resulted, on 15 April 1793, in a demand by the Paris Commune for his exclusion from the assembly, but Lanjuinais remained implacable - when the Parisian populace under François Hanriot invaded the convention on 2 June, he renewed his defiance of the victorious party.
Pursued by Jean-Baptiste Carrier, who was sent to stamp out resistance in the west, he lay hidden until some time after the outbreak of the Thermidorian Reaction (July 1794), but he was readmitted to the convention on 8 March 1795.
[1] He maintained his liberal and independent attitude in the Council of Ancients of the French Directory, the Senate of the Consulate and First Empire, and the Chamber of Peers, being president of the upper house during the Hundred Days.
He wrote a Notice historique sur la vie et les ouvrages du comte de Lanjuinais, which was prefixed to an edition of his fathers Œuvres (4 vols., 1832).
