The title of Marquess of Carisbrooke was created in the Peerage of the United Kingdom in 1917 for Prince Alexander of Battenberg, eldest son of Princess Beatrice of the United Kingdom (youngest daughter of Queen Victoria) and Prince Henry of Battenberg. Along with other German-surnamed relations of the British royal family, Alexander also changed his surname at this time, to Mountbatten. The title became extinct upon the 1st Marquess`s death in 1960, as he did not produce a male heir.
