The British Royal Family was closely related to its German enemies. Queen Victoria married the German Prince Albert of Saxe-Coburg-Gotha, whose German titles passed eventually to the descendants of their youngest son Leopold, Duke of Albany. Victoria's eldest daughter, also named Victoria, married Frederick III, German Emperor. Thus George V was a first cousin of William II, German Emperor and of Charles Edward, Duke of Saxe-Coburg and Gotha. A more distant relative was Ernest Augustus, Crown Prince of Hanover, who was descended in the male line from George III and thus was a Prince of Great Britain & Ireland.
Many members of the German royal families enjoyed British royal or noble titles leading to a call for the deprivation of their titles. In 1915, several Knights of the Most Noble Order of the Garter were struck off the Rolls of the Order; but peerage titles cannot be withdrawn except by Act of Parliament. In 1917, therefore, the Parliament passed the Titles Deprivation Act authorising the deprivation of peerage titles, as well as princely dignities.
Thereafter, a successor of a person thus deprived of a peerage is allowed to petition the Crown for restoration thereof; the petition is to be referred to a committee of the Privy Council, which may recommend whether the petitioner be reinstated or not.
Under the Act, the King appointed to the committee:
To date, no descendant of the persons who were deprived of their titles has petitioned the Crown for the restoration of the said titles.
