Jacques de Savoie, duke de Nemours (born Oct. 12, 1531, Vauluisant, Champagne, Fr.—died June 15, 1585, Annecy) was a noted soldier and courtier during the French wars of religion.
He won a military reputation in the French royal service on the eastern frontier and in Piedmont in the 1550s and against the Huguenots and their German allies in the 1560s. His amorous exploits at the Valois court were also admired; the chronicler Pierre de Brantôme characteristically calls him “the paragon of chivalry.” After being considered for marriage to Elizabeth I of England in 1559–60, Nemours became interested in Anne d’Este, wife of François de Lorraine, 2e duc de Guise; and after Guise’s death (1563) he repudiated a solemn promise of marriage to Mlle de La Garnache (Françoise de Rohan, who had borne him a son and whose cause was taken up by her Albret and Bourbon relatives) in order to marry Anne in 1566. He later retired to his Savoyard appanage of Genevois and died of the gout.
