context_page_description: Frederick of Nassau, Lord of Zuylestein was an illegitimate son of Frederick Henry, Prince of Orange, by Margaretha Catharina Bruyns,
context_section_description: Frederick was born in 1624 out of wedlock to Frederick Henry, Prince of Orange (1584 – 1647) and Margaretha Catharina Bruyns (1595–1625), who was the daughter of Ludolph Bruyns, mayor of Emmerich.
  On 15 March 1640, Frederick's father gave him Castle Zuylestein (also spelled Zuylenstein) - situated about twenty miles east of the city of Utrecht, and with it he also gave him the title Lord of Zuylestein (in Dutch: Heer van Zuylestein). Furthermore, he made Frederick captain of infantry for the state. 
  
  In 1659, Frederick was made governor of the household of his nephew, William III of Orange. Through lobbying by Johan de Wit, William III became the state's ward in 1666, and Frederick was dismissed. His dismissal was because he was married to an Englishwoman and was under suspicion of pro-English leanings. In April 1672 (the rampjaar) he became general of the infantry and in August he became involved in the murders of Johan and Cornelis de Wit.
