monarchy did not legally permit interregnums. But neither was crowned and both actively declined the throne. Gallery Downfall The February Revolution of 1917 resulted in the abdication of Nicholas II in favor of his brother Grand Duke Michael Alexandrovich. The latter declined to accept imperial authority save to delegate it to the Provisional Government pending a future democratic referendum, effectively terminating the Romanov dynasty's rule over Russia. After the February Revolution, Nicholas II and his family were placed under house arrest in the Alexander Palace. While several members of the imperial family managed to stay on good terms with the Provisional Government and were eventually able to leave Russia, Nicholas II and his family were sent into exile in the Siberian town of Tobolsk by Alexander Kerensky in August 1917. In the October Revolution of 1917 the Bolsheviks ousted the Provisional government. In April 1918, the Romanovs were moved to the Russian town of Yekaterinburg, in the Urals, where they were placed in the Ipatiev House. Here on the night of 16–17 July 1918, the entire Russian Imperial Romanov family along with several of their retainers were executed by Bolshevik revolutionaries, most likely on the orders of Vladimir Lenin. Contemporary Romanovs There have been numerous post-Revolution reports of Romanov survivors and unsubstantiated claims by individuals to be members of the deposed Tsar Nicholas II's family, the best known of whom was Anna Anderson. Proven research has, however, confirmed that all of the Romanovs held prisoners inside the Ipatiev House in Ekaterinburg were killed. Grand Duke Kirill Vladimirovich, a male-line grandson of Tsar Alexander II, claimed the headship of the deposed Imperial House of Russia, and assumed, as pretender, the title "Emperor and Autocrat of all the Russias" in 1924 when the evidence appeared conclusive that all Romanovs higher in the line of succession had been killed. Kirill was followed by his only son Vladimir Kirillovich. Vladimir's only child, Maria Vladimirovna (born 1953), claims to have succeeded her father. The only child of her marriage with Prince Franz Wilhelm of Prussia, George Mikhailovich, is her heir apparent. The Romanov Family Association (RFA) formed in 1979, a private organization of most living male-line descendants of Emperor Paul I of Russia (other than Maria Vladimirovna and her son), publicly acknowledges that dynastic claims of family members should not be advanced, and is officially committed to support which ever form of government chosen by
