CHAMPAGNY, JEAN BAPTISTE NOMPERE DE, DUC DE CADORE (1756-1834), French politician, was born at Roanne on Aug. 4, 1756, and entered the navy in 1774. He fought through the war in America and resigned in 1787. Elected deputy by the noblesse of Forez to the states-general in 1789, he went over to the third estate on June 21 and collaborated in the work of the Constituent Assembly, especially occupying himself with the reorganization of the navy. He remained in private life from 1791-99, when Napoleon named him member of the council of state. From July 18o1 to Aug. 1804 he was ambassador of France at Vienna and directed the incessant negotiations between the two courts. As minister of the interior (5804-7) he proved an ad ministrator of the first order. In Aug. 1807 he succeeded Talley rand as minister for foreign affairs. He directed the annexation of the Papal states in April 1808, worked to secure the abdication of Charles IV. of Spain in May 1808, negotiated the peace of Vienna (1809) and the marriage of Napoleon. In April 1811 a quarrel with the emperor led to his retirement. In 1814, after the abdication, the empress sent him on a fruitless mission to the emperor of Austria. Then he went over to the Bourbons. During the Hundred Days he again joined Napoleon. This led to his exclusion by Louis XVIII., but in 1819 he recovered his dignity of peer. He died in Paris on July 3, 1834. Three of his sons achieved distinction. Francois (1804-1882) wrote a history of the Roman empire, in three parts—(I) Les Cesars 4 vols.) ; (2) Les Antonin (1863, 3 vols.) ; (3) Les Cesars du III siecle (187o, 3 vols.) . Napoleon (1806-1872) published a Traite de la police municipale in 4 vols. (1844-61), and was a deputy in the Corps Legislatif from 1852-70. Jerome Paul (1809-86) was also deputy in the Corps Legislatif from 18J3-70, and was made honorary chamberlain in 1859. He worked on the official publica tion of the correspondence of Napoleon I.
