Charles Henri, Prince of Commercy

Charles Henri of Lorraine was the legitimated son of Charles IV, Duke of Lorraine, and Batrix de Cusance. He was given the Principality of Commercy in 1708 by his cousin Leopold, Duke of Lorraine. He was also the Count of Falkenstein.

Charles Henri was the third child and only surviving son of the second marriage of Charles IV, Duke of Lorraine . This second marriage, contracted while Duke Charles was in exile, was not canonically recognized because the separation between the duke and his first wife, Nicole de Lorraine, was not recognized as a valid annulment by the Holy See. Charles Henris claim to inherit Lorraine was therefore disputed, and rule of the duchy had been obtained by his fathers younger brother through French intervention. He was born in Brussels.
