The Royal Guelphic Order, sometimes referred to as the Hanoverian Guelphic Order, is a Hanoverian order of chivalry instituted on 28 April 1815 by the Prince Regent. It takes its name from the House of Guelph, of which the Hanoverians were a branch. Since Hanover and the United Kingdom shared a monarch until 1837, the order was frequently bestowed upon British subjects.
