Canonization of the Romanovs
The canonization of the Romanovs (also called "glorification" in the Eastern Orthodox Church) was the elevation to sainthood of the last imperial family of Russia – Tsar Nicholas II, his wife Tsarina Alexandra, and their five children Olga, Tatiana, Maria, Anastasia, and Alexei – by the Russian Orthodox Church. The family was murdered by the Bolsheviks on 17 July 1918 at the Ipatiev House in Yekaterinburg.
