Charles-Emmanuel de Savoie, prince de Genevois and duc de Nemours (c.–13 August 1595) was a French prince étranger, governor, military commander and rebel during the latter French Wars of Religion. The eldest son of Jacques de Savoie and Anne d'Este, Nemours was a member of a prominent princely family. He entered French political at the age of 18 as a partisan of the second Catholic ligue, rallying cavalry to the rebel army, and assisting in forcing Henri III to capitulate to their demands. In the following years, the king was compelled by the terms of the peace to make war against Protestantism. The former rebel ligueurs hoped the 'cowed' king would afford them advantage, but Henri was keen to dilute the authority of the former rebels. As a result Nemours' position as colonel-general of the light cavalry was diluted with several appointments of royal favourites. During this period, Nemours coveted the governate of the Lyonnais, which had previously been held by his father before 1571. When François de Mandelot, who held the office, died in November 1588, Henri was compelled to recognise Nemours as the new governor due to his political weakness. Frustrated at his continued capitulations to the ligue, on 23 December 1588, Henri assassinated the leader of the ligue the duke of Guise. In the wake of the assassination, Nemours and other ligueur leaders were arrested by the king. Nemours was however quickly able to bribe his guards and secure freedom.
