a Countess of Nassau, granddaughter of William I, Prince of Orange, "William the Silent", and an Electress of Brandenburg. Louise Henriëtte had to abandon her love for Henri Charles de La Trémoille, Prince of Talmant, son of Henry de La Trémoille, as her mother had royal ambitions for her. However, attempts to conclude an engagement with King Charles II of England came to nothing. Finally she was forced to marry Frederick William, Elector of Brandenburg (1620-1688), "the Great Elector," at The Hague on 7 December 1646, her nineteenth birthday.
