Guillermo de Orange
The execution of Lamoral, Count of Egmont in 1568 helped spark the Dutch Revolt that eventually led to the independence of the Netherlands, while Anna van Egmond-Buren, known as Anna van Buren in the Netherlands, was the first wife of William the Silent, the leader of this national uprising. Ironically, in 1573 both Egmond Abbey and Egmond Castle were destroyed on order of William the Silent.
