After the war he spent most of his time in
Madrid, with frequent stays at his property in
Brittany, as well as in Paris. Vladimir married
Princess Leonida Georgievna Bagration-Moukhransky on 13 August 1948 in
Lausanne. Pre-revolutionary
Romanov house law dictated that only those born of an "
equal marriage" between a Romanov
dynast and a member of a "royal or sovereign house", were included in the Imperial line of succession to the Russian throne; children of
morganatic marriages were ineligible to inherit the throne or dynastic status. The family to which Princess Leonida belonged, the
Bagrationi dynasty, had been kings in
Georgia from the
medieval era until the early 19th century, but no male line ancestor of hers had
reigned as a king in Georgia since 1505 and her branch of the Bagrationis, the
House of Mukhrani, had been
naturalised among the non-ruling
nobility of Russia after Georgia was annexed to the
Russian Empire in 1801. Yet the royal status of the House of Bagrationi had been recognized by Russia in the 1783
Treaty of Georgievsk and was confirmed by Vladimir Kirillovich on 5 December 1946 as claimed head of the Russian imperial house. However the last ruling emperor of Imperial Russia Nicholas II had deemed marriage in this family of Princess Tatiana Constantinova in 1911, as morganatic. Following Vladimir's public designation of his daughter as "curatrix of the throne", in anticipation that she would eventually succeed him as head of the dynasty in exile, the heads of three of the other branches of the imperial family — the Princes
Vsevolod Ioannovich (
Konstantinovichi),
Roman Petrovich (
Nikolaevichi) and
Andrei Alexandrovich (
Mihailovichi) — wrote to Vladimir in 1969, asserting that the dynastic status of his daughter was no different from that of their own children (Vsevolod Ioannovich was childless, but Roman Petrovich had two sons by Countess Prascovia
Sheremetyev, while Andrei Alexandrovich had two sons by Donna Elisabeth
Ruffo of a Russian branch of the Princes di San Sant' Antimo) and that his wife was of no higher status than the wives of the other Romanov princes. In 1952 he called on the
Western powers to wage war against the Soviet Union. On 23 December 1969 Vladimir issued a controversial decree whereby in the event he predeceased the living male Romanovs that he recognised as dynasts then his daughter Maria would become the "Curatrix of the Imperial Throne". This has been viewed as an attempt by Vladimir to ensure the succession remained in his branch of the imperial family, while the heads of the other branches declared that Vladimir's actions were illegal. Vladimir was able to visit Russia in November 1991 when he was invited to visit
St Petersburg by its Mayor
Anatoly Sobchak. ==Death and succession dispute==
