Eugène-Alexandre de Montmorency-Laval

Eugène-Alexandre de Montmorency-Laval, 4th Duke of Laval (20 July 1773 – 2 April 1851), was a 19th-century French soldier.

Early life Eugène-Alexandre was born on 20 July 1773. He was the fourth son of Anne-Alexandre-Marie de Montmorency-Laval, 2nd Duke of Laval, and Marie-Louise de Montmorency-Luxembourg (1750–1829), a daughter of Count Joseph Maurice Annibal de Montmorency-Luxembourg.

His paternal grandparents were Guy André Pierre de Montmorency-Laval, 1st Duke of Laval, and Jacqueline de Bullion de Fervaques.

Career Like his elder brother Achille (who died of a wound he received in the defense of Bundenthal), he fought in the campaigns of 1793, 1794 and 1795, in the Army of Condé. Returning to France, he became a member of the right-wing royalist organisation known as the Chevaliers de la Foi (Knights of Faith).

He became Marshal of the King's Camps and Armies and a Knight of the Royal and Military Order of Saint-Louis, before he was promoted to Lieutenant-General of the Armies.

The Duke died, without issue, on 2 April 1851, upon which the dukedom of Laval became extinct. He left the Château de Beaumesnil to his brother-in-law, Rodolphe de Maistre, Count of Maistre.
