Gascons remained deeply loyal to their families and after proving themselves in battle often helped their relatives rise through the royal military ranks, forming strong networks of influence.
D’Artagnan was no exception. Throughout his military career he supported members of his family. He secured a position of sub-lieutenant for his first cousin, Jean-Louis Castéra de La Rivière, and took two other cousins under his wing: Pierre and Joseph de Montesquiou d’Artagnan.
Their paths illustrate both the opportunities and the challenges of rising under Louis XIV. Pierre represented the discipline and reform-mindedness of a great military leader, while Joseph embodied the struggles of a young nobleman confronted with the demands of court life and the distractions of Paris. D’Artagnan remained a loyal patron to both, despite his own financial constraints.
