William III and Mary II - The Greatest Royal Betrayal in British History Documentary

This video traces the unlikely rise of William of Orange from a posthumous, politically vulnerable infant to the Stadtholder of the Dutch Republic and, ultimately, King of England. It opens with the crisis of 1672, when a French invasion overwhelmed the Dutch and forced them to break their own dams, leading to William's appointment as Stadtholder and the violent deaths of the De Witt brothers. The narrative then pivots to his origins, explaining how his father died just days before his birth, triggering a fierce guardianship battle and the First Stadtholderless Period. Raised mainly by his grandmother Amalia, William was given a Calvinist education and surrounded by British connections through his mother, Princess Mary, a daughter of Charles I. These early influences, coupled with the Dutch tradition of the House of Orange as quasi-royal leaders, set the stage for his later dual monarchy with Mary Stuart.
