Karl Ludwig Ficquelmont, count, an Austrian general and statesman, born at Dieuze, Lorraine, March 23, 1777, died in Venice, April 7, 1857. He was a son of Count Joseph, who, after emigrating from Lorraine to Austria, died in 1799 from a wound received at the battle of Magnano. He entered the Austrian army, and in 1809 was colonel and chief of the staff of the grand duke Ferdinand of Este. In 1811 and 1812 he commanded three regiments of cavalry in Spain under Wellington. In 1813 he was promoted to the rank of major general, and in 1814 he brought about the capitulation of Lyons. He was afterward sent on several important diplomatic missions. He was minister of foreign affairs during Metter-nich's temporary absence from Vienna in 1839, and in 1840 became a member of the cabinet. During the revolution of 1848 he was for a short time minister of foreign affairs, and then provisional prime minister, till May 4, when he retired on account of a hostile demonstration of the people, who looked upon him as a disciple of Metternich; but he continued to exercise important influence in the affairs of the empire. He wrote several political pamphlets, some of which, as Lord Pahnerston, England und der Continent (Vienna, 1852), and Zum kunftigen Frieden (1856), attracted considerable attention.

Les pensees et reflexions morales et politiques du comte deFicquelmont appeared in Paris in 1859, with a biographical notice by M. de Barante.
