The Duke and Duchess of Cambridge were joined by Queen Elizabeth as William was installed into the historic Order of the Thistle, effectively making him a Knight of the Thistle.
St. Giles Cathedral was quite the scene to behold, as bigwigs like the Duek of Edinburgh and 400 bagpipers also showed up for the thrilling event.
During the ceremony, William promised to be “loyal and true to my Sovereign Lady the Queen, and the members of this Order. I shall maintain the honor and dignity of the most ancient and most noble Order of the Thistle to the best power if God let. I shall never bear treason about in my heart against our Sovereign Lady the Queen, but shall discover the same to her. So defend me God.”
