With an Order in Council dated 9 June 1911, his brother-in-law King George V, as a gift to mark his own Coronation, granted his cousin the style "His Highness", which echoed the gift of the King's grandmother, Queen Victoria, to the Duke's father. The same year he was made a Knight Grand Cross of the Order of the Bath (GCB). From other nations he received the grand cross of the Order of the Red Eagle of Prussia, the Order of the Iron Crown of Austria, and the grand cross first class of the Order of the Star of Romania.
