Charles de Beauharnois de La Boische, Marquis de Beauharnois
Charles de Beauharnois de La Boische Beauharnois, Marquis de Beauharnois, (baptized 12 October 1671 in La Chaussaye, near Orléans, France; died 12 July 1749 in Paris, France). Beauharnois was a naval officer in the wars of Louis XIV. From 1726 to 1747, he was the governor of New France. He initially built upon Indigenous alliances and defended New France from British incursions. However, the loss of Louisbourg in 1745 and the subsequent deterioration of relationships with Indigenous allies both occurred under Beauharnois and contributed to the eventual conquest of New France.
