In the RevolutionEdit

Born in Montfort-en-Chalosse, Aquitaine (now in Landes department), he was elected deputy to the Convention by the département of the Landes. He sat in The Plain (the party which had no clear attitude, and served to sway the vote). He voted for the death of King Louis XVI, without appeal or delay, but was not prominent in the Convention afterwards.[1]

Ducos was a member of the Council of Five Hundred, over which he presided on the 18th of Fructidor Coup (1797). At the end of his term, he became a justice of the peace, but after Barthélemy Catherine Joubert's coup d'état (the 30 Prairial of the year VIII, or 18 June 1799), he was named a member of the executive Directory, thanks to the influence of Paul Barras, who counted on Ducos as his partisan.[1]

Consulate, Empire, and exileEdit

On 9 November 1799, Ducos accepted the coup d'état of Napoleon Bonaparte (the 18 Brumaire), and was one of the three Provisional Consuls (with Napoleon and Emmanuel-Joseph Sieyès), becoming vice-president of the Senate with the arrival of a stable Consulate formula. He was many times honored under the Empire, but in 1814 he abandoned Napoleon, and voted for his deposition.[1]

He sought to gain the favor of the government of the Restoration, but in 1816 was exiled on the basis of the law regarding the regicides. He died in March 1816 near Ulm, from a carriage accident.[1]
