George V

From then on, his naval rank was largely honorary.

As a young man destined to serve in the navy, Prince George served for many years under the command of his uncle, Prince Alfred, Duke of Edinburgh, who was stationed in Malta. There, he grew close to and fell in love with his uncle's daughter, his first cousin, Marie of Edinburgh. His grandmother, father and uncle all approved the match, but the mothers—the Princess of Wales and the Duchess of Edinburgh—both opposed it. The Princess of Wales thought the family was too pro-German, and the Duchess of Edinburgh disliked England. Marie's mother was the only daughter of the Tsar of Russia. She resented the fact that, as the wife of a younger son of the British sovereign, she had to yield precedence to George's mother, the Princess of Wales, whose father had been a minor German prince before being called unexpectedly to the throne of Denmark. Guided by her mother, Marie refused George when he proposed to her. Read Less

The tour was almost immediately followed by a trip to Spain for the wedding of King Alfonso XIII to Victoria Eugenie of Battenberg, at which the bride and groom narrowly avoided assassination. A week after returning to Britain, George and May travelled to Norway for the coronation of King Haakon VII and Queen Maud, George's sister. Read Less

He and all his British relatives relinquished their German titles and styles, and adopted British-sounding surnames. George compensated his male relatives by creating them British peers. His cousin, Prince Louis of Battenberg, who earlier in the war had been forced to resign as First Sea Lord through anti-German feeling, became Louis Mountbatten, 1st Marquess of Milford Haven, while Queen Mary's brothers became Adolphus Cambridge, 1st Marquess of Cambridge, and Alexander Cambridge, 1st Earl of Athlone. George's cousins Princess Marie Louise and Princess Helena Victoria of Schleswig-Holstein dropped their territorial designations.

In Letters Patent gazetted on 11 December 1917, the King restricted the style "His (or Her) Royal Highness" and the titular dignity of "Prince (or Princess) of Great Britain and Ireland" to the children of the Sovereign, the children of the sons of the Sovereign and the eldest living son of the eldest living son of a Prince of Wales. The Letters Patent also stated that "the titles of Royal Highness, Highness or Serene Highness, and the titular dignity of Prince and Princess shall cease except those titles already granted and remaining unrevoked". Relatives of the British Royal Family who fought on the German side, such as Prince Ernst August of Hanover, 3rd Duke of Cumberland and Teviotdale (the senior male-line great grandson of George III) and Prince Carl Eduard, Duke of Albany and reigning Duke of Saxe-Coburg and Gotha (a male-line grandson of Queen Victoria), were cut off; their British peerages were suspended by a 1919 Order in Council under the provisions of the Titles Deprivation Act 1917.
