REVERSAL OF ALLEGIANCE
Since, at the death of GEORGE THE THIRD, King of the United Great Britain and Irland, also King of Hannover, Herzog of Braunschweig and Lüneburg and of all lands under his jurisdiction have been inherited under the inheritance law of the first-born by GEORGE THE FOURTH, I am recognizing him alone as my rightful lord; I swear to serve him faithfully to the best of my ability and conscience, as much as I can, to also hold him from harm and damage with my best capability.
To document this, I have signed this reversal with my full name in my own handwriting.
Schönhagen, the 17th of July 1820
