A Brief History
Nicholas II, Emperor and Autocrat of All Russia (6 May 1868 to 4 July 1918 in the Julian Calendar, or 18 May 1868 to 17 July 1918 in the Gregorian Calendar), was the last Emperor of Imperial Russia. He ruled from November 1, 1894 until his abdication on March 15, 1917, and was killed with his family in 1918.
Nicholas's full name was Nikolai Aleksandrovich Romanov. His official title was Bozhiyeyu Milostiyu, Imperator i Samodyerzhets Vserossiysky (By the Grace of God, Emperor and Autocrat of All Russia). The title Tsar (or Czar), derived from the Roman title Caesar via the Byzantine form Kaisar, had been officially abolished in 1721 by Peter the Great, but it was informally used throughout Nicholas's reign.
