clause of the treaty would also be recalled during obscure late 20th century debates about restoration of the Russian monarchy. In 1948, Vladimir Kirillovich Romanov, (1917–1992), pretender to Russia's throne, married Princess Leonida Georgievna Bagration-Moukhranskaya, (born 1914), a descendant of the Mukhranbatoni who negotiated the 1783 treaty, and thus a member of the once royal House of Bagrationi. The marriage produced an only child, Maria Vladimirovna, (born 1956), who has taken up her father's claim as Russia's de jure monarch. She and her son, George (born of her former marriage to Prince Franz Wilhelm of Prussia), have pretended to the Romanovs’ old grand ducal title. Her supporters argue that her father's marriage to Leonida, alone among those contracted by Romanov males in exile since 1917, complied with the Romanov house law that required marriage to a princess of a "royal or ruling family" in order for descendants to claim the throne. That law also provided that upon extinction of all male dynasts, female Romanovs born of dynastic mothers become eligible to inherit the crown. Based on this rationale, Maria purports to have the strongest legal claim to the Russian throne in the event that Russia ever restores its monarchy. Critics deny that Princess Leonida could be reckoned of royal rank by Romanov standards (the title of prince was one of nobility, not dynasty in Russia, except in the imperial family). They point out that the Bagration-Mukhranskys were demoted from dynastic status and incorporated into Russia's ordinary nobility by 1833: Though the princess descended patrilineally from a dynasty that had ruled as kings in Armenia and Georgia since the Middle Ages, it had been reduced to the status of Russian nobility for over a century prior to the Russian Revolution. Leonida's branch of the Bagratids, although genealogically senior, had not been regnant in the male line as kings of Georgia since 1505. Members of the family accepted court appointments under Russia's emperors incompatible with claims to dynastic dignity. Moreover, when an imperial Romanov princess wed Prince Constantine Bagration-Mukhransky in 1911, the marriage was officially deemed non-dynastic by Nicholas II, and the bride, Tatiana Konstantinova Romanova, was obliged to renounce her succession rights. While these facts are admitted, it is counter-argued that the demotion of the Bagratids, including the Mukhrani branch, violated the Treaty of Georgievsk and therefore failed to legally deprive any Bagrationi of royal rank. That fact, it is claimed,
