Antoine De Bourbon, duke of Vendome, and afterward king of Navarre, the father of Henry IV. of France, born in 1518, died Nov. 17, 1502. He married in 1548 Jeanne d'Albret, only child of Henry II., king of Navarre, and assumed the title of king in her right. Like his brother, the duke of Conde, he embraced Protestantism. After the accession to the throne of France of the young king Francis II. (1559), he endeavored to obtain the control of the affairs of that country, but failed through his want of energy and perseverance. On the death of Francis in 1500, he was made lieutenant general of the kingdom, and adviser to the queen mother (Catharine de' Medici), during the minority of Charles IX. He then abandoned his former associates and religion, and allied himself with the duke of Guise and the constable de Montmorency. Upon the breaking out of the civil war in 1562, he commanded the royal forces, and died of a wound received at the siege of Rouen.
