The House of Beauvau was the name of a historic French noble family originating in Anjou, whose members held significant political and military positions in France, Spain and the Holy Roman Empire.
The Beauvau du Rivau branch was rooted in Brittany and produced two bishops of Nantes, whilst the Craon (Prince of Craon) branch was established in Lorraine later enjoying great intimacy with the then reigning ducal family.
As with the comtes d'Anjou, the Beauvaus served the kings of France right up to the 18th century.
The title of marquis of Beauvau was granted to the head of the family by Louis XIV in 1664.
The Beauvau arms were d'argent à 4 lionceaux de gueules armés, lampassés et couronnés d'or.
