Charlotte de Bourbon, a member of the French royal family, was brought up to be a nun and became the abbess of a French convent. Changing her religion, she escaped from the convent and, fleeing to Germany, sought refuge with the Elector Palatine. After a while she accepted the marriage proposal from the Prince of Orange and they became the parents of six daughters. On instigation of King Philip II of Spain, the Prince of Orange was almost assassinated. A subsequent attempt in 1584 would succeed. But previously in 1582, Charlotte de Bourbon, while trying to nurse her husband, herself died. Three daughters went to Germany and three to France; one of these latter returned many years later to the Catholic religion to become a nun and an abbess in turn.
