Hyde de Neuville, Jean-Guillaume, Baron

▪ French diplomat

born Jan. 24, 1776, La Charité, France

died May 28, 1857, Paris

 diplomat and one of the most consistent defenders of Bourbon Legitimism.

      Devoted to Louis XVI, Hyde de Neuville remained a royalist agent after the outbreak of the Revolution. After taking part in a royalist insurrection in Berry (1796), he attempted first to discredit the Directory, then to convince Napoleon to reestablish the Bourbons on the throne. He left France in 1804, reached the United States in 1806, and remained there until 1814.

      Upon his return to France after the First Restoration, Hyde de Neuville was employed by Louis XVIII on a mission to Italy. He was elected to the Chamber of Deputies (1815), and he served as ambassador of France to the United States (1816–21) and to Portugal (1823–24). For his role in saving King John VI of Portugal from an attempted coup d'etat, he was named count of Bemposta in 1824. He returned to France again and sat in the Chamber of Deputies, and in 1828 he became minister of the navy. In 1830 he opposed the exclusion of the Duc de Bordeaux, the rightful Bourbon claimant, from succession to the throne; following the Duc's defeat Hyde de Neuville resigned his seat.
