Willem of Orange marries duchess Anna of Saxony.

William the Silent or William the Taciturn, more commonly known in the Netherlands as William of Orange, was the leader of the Dutch revolt against the Spanish Habsburgs that set off the Eighty Years' War (1568–1648) and resulted in the formal independence of the United Provinces in 1648. Born into the House of Nassau, he became Prince of Orange in 1544 and is thereby the founder of the Orange-Nassau branch and the ancestor of the monarchy of the Netherlands. In the Netherlands, he is also known as Father of the Fatherland.

Anna of Saxony was the daughter of Maurice, Elector of Saxony, and Agnes of Hesse. Her wealth drew many suitors; she ultimately accepted the proposal of widowed William the Silent, and they were married on 25 August 1561. They had to flee the Netherlands in 1567 in the face of the Habsburg army dispatched to suppress the Dutch Revolt.

August 24 is the 236th day of the year in the Gregorian calendar; 129 days remain until the end of the year.
