the third and youngest daughter of William the Silent and his second wife Anna of Saxony. After her father's death she acted as hostess at the court of her brother, Maurice. It was on one of those occasions that she met Dom Manuel de Portugal, (son of pretender to the Portuguese throne, António, Prior of Crato). She secretly wed him in 1597. Maurice was firmly opposed to the marriage, because the Nassaus were Calvinists and Dom Manuel was a Catholic.
