The de Montesquiou family is a very old French noble family from Gascony. Its motto is Deo duce et ferro comite ("God as guide and my sword as companion").

The family divided in several branches, of which only the branch of d'Artagnan now remains.

Through the centuries, the Montesquiou family produced one field marshal, one admiral, one Cardinal, one archbishop, four generals, four bishops, one minister, several diplomats.

In 1777 Louis XVI allowed the Montesquiou family to change its name as de Montesquiou-Fezensac.

In 2011 certain members of the d'Artagnan branch changed their name to de Montesquiou-Fezesensac d'Artagnan.

The titles of the Marsan line (extinct) were:

  • baron of the Empire (1809)[1]
  • count of Montesquiou (1817)[2]).
  • duke of Fezensac in 1821 and 1832 (title extinct in 1913 with Philippe André, third duke of Fezensac[2]).
