In the great conflict of the period between Napoleon I and the Bourbons, Berryer, like his father, was an ardent Legitimist; and in the spring of 1815, at the opening of the campaign of the Hundred Days, he followed Louis XVIII of France to Ghent as a volunteer.
After the Revolution of 1830, he was given command of military forces in order to suppress Legitimist risings against the new July Monarchy of Louis-Philippe.
The French and Spanish claims separated again at Alfonso's death, as his eldest surviving son Infante Jaime renounced his claim to the Spanish throne due to physical disability and, some years later, asserted a claim to the French succession based on Legitimist principles.
Lannes at first appeared, by his votes, to be linked to the Legitimist faction (which supported the claims to the Throne of the elder line of the House of Bourbon), but he was soon to join fully in support of the July Monarchy and usually then voted with the Doctrinaires.
Marie Marguerite of Bourbon, Duchess of Anjou (née María Margarita Vargas Santaella; born 21 October 1983, Caracas) is a Venezuelan heiress and wife of Louis Alphonse of Bourbon, Duke of Anjou, who is considered by Legitimists to be the head of the French Royal House making Marie Marguerite the Legitimist titular queen consort of France.
