Russia After 1886, great-grandchildren of Russian emperors in the male-line were Prince[ss] of Russia, and were to be granted the treatment of Highness, and Prince[ss] of Russia with the style of Serene Highness if being more distantly descended from an emperor, and born from an equal marriage (as opposed to Morganatic marriage). An exception was for each eldest son of senior imperial great-grandsons (in the patrilineal descent of each son of the emperor), who retained the higher style of Highness. Strictly, the Russian term, Svetlost, was an honorific used in adjectival form (Светлейший: Svetleyshiy, Most Serene) to refer to members of a select few of Russia's princely families (e.g. "The Serene" Prince Anatoly Pavlovich Lieven or "The Serene" Prince Dmitri Vladimirovich Golitsyn). However, when translated into non-Slavic languages and used in reference to a member of the imperial Romanov family, it was usually rendered as Serene Highness. United Kingdom Queen Victoria elevated each of the princes who married her daughters to Royal Highness (except for Crown Prince Friedrich of Prussia, husband of Victoria, Princess Royal, who already possessed the HRH). This included, on 30 January 1884, HSH Prince Henry of Battenberg, husband of Princess Beatrice. That couple's children were granted the style of Highness by their British grandmother by letters patent 4 December 1886. Several morganatic branches of reigning German dynasties took up residence in the United Kingdom in the 19th century, where their German princely titles and style of Serene Highness were recognized by the sovereign. Included in this group were Princess Edward of Saxe-Weimar, Princess Victor of Hohenlohe-Langenburg, the dukes and princes of Teck and the princes of Battenberg. During World War I, King George V revoked recognition of the style Serene Highness, hitherto used by some relatives of the British Royal Family who used German princely titles but lived in Britain. George V's queen consort was born "Her Serene Highness Princess Mary of Teck", and Prince Philip's mother had been born "Her Serene Highness Princess Alice of Battenberg". The Tecks (descended from the royal House of Württemberg) and the Battenbergs (descended from the Grand Dukes of Hesse and by Rhine) were compensated with multiple peerages, viz. Marquess of Cambridge and Earl of Athlone for the former, and Marquess of Milford Haven and Marquess of Carisbrooke for the latter.
