George IV a vécu la majeure partie de son règne seul au château de Windsor , mais il continua de s'immiscer dans les affaires politiques. Au début, on crut qu'il apporterait son soutien à l'émancipation des catholiques car en 1797, il avait présenté une loi d'émancipation pour les catholiques irlandais, mais ses vues anti-catholiques devinrent claires dès 1813.
William IV (William Henry; 21 August 1765 – 20 June 1837) was King of the United Kingdom of Great Britain and Ireland and King of Hanover from 26 June 1830 until his death in 1837. The third son of George III, William succeeded his elder brother George IV, becoming the last king and penultimate monarch of Britain's House of Hanover.
Because of the postponement of George IV's coronation due to the trial of his wife, Queen Caroline, the final bill for the hiring of the stones came to £24,425. After his coronation, the king was reluctant to part with his new crown, and lobbied the government to buy it outright so he could use it for the annual State Opening of Parliament , but it was too expensive.
