Duke of Beaufort (France)

Duke of Beaufort (French: duc de Beaufort) was a title in the French nobility.

The dukedom was first created in 1597 as a peerage for Gabrielle d'Estrées, Marchioness of Monceaux, the mistress of King Henry IV, with a remainder to their illegitimate son César, who later also became Duke of Vendôme.

The duchy (i.e. the lands associated with the dukedom) was sold by the 5th Duke of Beaufort in 1688 to Charles François Frédéric de Montmorency-Luxembourg, who was created Duke of Beaufort without a peerage that same year. The dukedom of Beaufort was renamed dukedom of Montmorency in 1689. He later succeeded as Duke of Piney-Luxembourg.
