Nicholas II of Russia
Nicholas II abdicated following the February Revolution of 1917 during which he and his family were imprisoned first in the Alexander Palace at Tsarskoe Selo, then later in the Governor's Mansion in Tobolsk, and finally at the Ipatiev House in Yekaterinburg. Nicholas II, his wife, his son, his four daughters, the family's medical doctor, the Tsar's Valet, the Empress' Lady in Waiting and the family's cook were all killed in the same room by the Bolsheviks on the night of 17 July 1918. This led to the canonization of Nicholas II, his wife the Empress and their children as martyrs by various groups tied to the Russian Orthodox Church within Russia and, prominently, by the Russian Orthodox Church outside Russia.
