The House of Crussol (formerly Bastet), is a surviving family of French nobility, originally from Languedoc.

The title, Duke of Uzès, was given to the family in 1565 and the Peerage in 1572.

The Crussol family has proven its nobility since 1215 and was admitted to the honors of the Court in the 18th century.

Gérald Bastet was a nephew of Odon de Chaponay, Bishop of Valence.

[3] In 1486, Jacques de Crussol acquired the viscountcy of Uzès from his marriage to Simone d'Uzès, on condition that he bear the name and arms of Uzès.
