Throughout his life George IV shone when he appeared at state occasions. He commissioned new diamond-set insignia and introduced new orders of chivalry in the wake of the Napoleonic Wars. His coronation was the most spectacular event of his life. The king himself was closely involved in all aspects of the ceremony, including the design of his costume and a dazzling diamond headdress. In the months following his coronation George IV visited Dublin, Hanover and Edinburgh to great public acclaim.
