Pierre Victurnien Vergniaud, a French revolutionist, born in Limoges, May 31, 1759, executed in Paris, Oct. 31,1793. He was admitted to the bar in Bordeaux in 1781, where he gained great distinction. He warmly supported the revolution of 1789, and in 1791 was elected to the legislative assembly, of which he became vice president (Oct. 16) and president (Oct. 31). He advocated severe measures against the emigrants, acted generally in opposition to the monarchy, promoted the proclamation of the republic in 1792, and was elected to the national convention. On the trial of the king he supported the proposition to allow an appeal to the people; but this being defeated, he voted for his execution without delay, and as president pronounced the sentence. From this time until the downfall and arrest of the Girondists (May 31 and June 2, 1793), of whom he was the most eloquent leader, he was engaged in a continual struggle against Robespierre and the ultra-revolutionists (montagnards). He appeared with his friends before the revolutionary tribunal, Oct. 24, and made a bold and eloquent defence, but with his colleagues was sentenced to death, Oct. 30. His most important speeches are contained in Choix de rapports, opinions et discours (Paris, 1818-'25). - See Histoire parlementaire et vie intime de Vergniaud, by Touchard-Lafosse (1848).
