The Counts of Astarac fr first appeared around 920 C.E., when the Duke of Gascony, García II, known as le Courbé, divided his lands between his sons.

[2] His descendants played a key role in the history of southern France, between the powerful counties of Toulouse, Foix, and Comminges and the kingdoms of Navarre and Aragon.

[3] His eldest daughter, Marthe, became Countess of Astarac, passing on the title to her husband Gaston III de Foix-Candale[fr] and their descendants.

[6] According to Régis Valette[fr], this family was declared noble in 1784,[7] but Henri Jougla de Morenas writes that the original 1784 ruling of the Montpellier Court of Auditors has not been found.

For its admission to the fr:Association d'entraide de la noblesse française, this family presented a written request to the assembly of the nobility, seneschal of Toulouse, on 23 July 1789, and provided noble qualifications on eight degrees.
