Gaston of Foix, Duke of Nemours (d. 1512)
Gaston de Foix, duc de Nemours (10 December 1489 – 11 April 1512), byname The Thunderbolt of Italy, was a famed French military commander of the Renaissance. Nephew of King Louis XII of France and general of his armies in Italy from 1511 to 1512, he is noted for his outstanding military feats in a career which lasted no longer than a few months. The young general is regarded as a stellar commander well ahead of his time. An adept of lightning fast forced marches as well as sudden and bold offensives that destabilized contemporary armies and commanders, De Foix is mostly remembered for his brilliant six-month campaign against the Holy League in the War of the League of Cambrai. He met his end in said conflict, at the age of 21, during the Battle of Ravenna (1512), the last of his triumphs.

Born in Mazères, County of Foix, he was the second child but only son of John of Foix, Viscount of Narbonne and Marie d'Orléans. His older sister was Germaine of Foix, Queen consort of Aragon as the second wife of Ferdinand II.

His paternal grandparents were Gaston IV of Foix-Grailly and Queen regnant Eleanor of Navarre. His maternal grandparents were Charles, Duke of Orléans and Marie of Cleves. His only maternal uncle was Louis XII of France.
