Life

He grew up with his elder brother, Louis Auguste de Bourbon, Prince of Dombes and his younger sister Louise Françoise de Bourbon (1707–1743), known as Mademoiselle du Maine.

Like his siblings he remained unmarried and childless all his life. On his father's death in 1736 he gained the title of Duke of Aumale. He was also made Grand Master of the Artillery. a post that his father had also held.

His elder brother was their father's main heir, but when he was killed in a duel in 1755 Louis Charles inherited his brother's estate. He was given his brother's governorship of Languedoc and inherited his brother's many châteaux.

Like his cousin, Louis Jean Marie de Bourbon, Duke of Penthièvre, Louis Charles was popular as a result of his charitable donations. In 1773 he offered to sell the dukedom of Aumale, countship of Eu and the estate of Anet to Louis XV for 12 million livres.
