Marie of Cleves, Princess of Condé

Marie of Cleves or of Nevers (Marie de Clèves, Marie de Nevers; 1553–1574), by marriage the Princess of Condé, was the wife of Henry, Prince of Condé, and an early love interest of King Henry III of France. She was the last child of Francis I of Cleves, Duke of Nevers, and Margaret of Bourbon-Vendôme, elder sister of Antoine of Navarre.
Her older sisters were Henriette of Cleves and Catherine of Cleves. King Henry IV of France was her maternal first cousin, and Anne of Cleves, the fourth wife of Henry VIII of England, was her second cousin once removed. Her brothers-in-law were Henry I, Duke of Guise and Louis Gonzaga, Duke of Nevers.
She was brought up by her aunt Queen Joan III of Navarre, who raised her as a Calvinist. In 1572 she married in a Calvinist ceremony her first cousin, Henri I de Bourbon, prince de Condé, duc d'Enghien. A few months later, after the St. Batholomew massacre, the couple had forcibly been converted to Roman Catholicism and remarried according to Catholic rites. When her husband fled the court and rejoined the Protestant cause, she refused and stayed behind at court remaining a Catholic the rest of her life.
Known for her beauty, Marie caught the eye of the young Henry, Duke of Anjou, the future Henry III of France, sometime before 1574. Upon ascending the throne later that year, Henry intended to procure Marie a divorce from her husband and marry her himself; however, Marie died before he could implement his plan. Sources vary on her cause of death but it is given as either a lung infection or complications from childbirth as Marie had recently given birth to her and Henry's first child, Catherine (1574–1595), Marquise d'Isles.
Henry, Prince of Condé would go on to remarry Charlotte Catherine de La Trémoille (1568−1629), while the now King Henry III would mourn for several months and eventually marry Louise de Lorraine-Vaudémont, who greatly resembled Marie.
