Explanation:
Nikolai Aleksándrovich Románov was the last Russian czar. Nicholas II of Russia, son of Alexander III, ruled from the death of his father, on October 20, 1894, until his abdication on March 2, 1917 (according to the Julian calendar), when he resigned in his name and on behalf of of his son heir to the throne and this passed to his brother, Grand Duke Michael. During his reign he saw how the Russian Empire suffered an economic and military debacle. He was nicknamed "Nicholas the Bloodthirsty" by critics due to the Jodynka Tragedy, Bloody Sunday and the anti-Semitic pogroms that occurred during his reign. As head of state, he approved the mobilization of August 1914 that marked the beginning of the First World War, the revolution and the consequent fall of the Romanov dynasty.
The February Revolution of 1917 ended his reign when, trying to return from the headquarters to the capital, his train was arrested in Dno, gubernatorial Pskov, and was forced to abdicate. From then on, the tsar and his family were imprisoned, first in the palace of Alexander, in Tsarskoye Selo, then in the house of the governor of Tobolsk and finally in the Ipátiev House, in Yekaterinburg. Nicholas II, his wife, his son, his four daughters, the doctor of the imperial family, a personal servant, the waitress of the Empress and the family cook were executed in the basement of the house by the Bolsheviks at dawn July 16-17, 1918. Later, Nicholas II, his wife and children were canonized as martyrs by the Russian Orthodox Church in exile.
