Czar Nicholas II who is he

   known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer, was the last Emperor of All Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917.

Explanation:

Nicholas II was the last tsar of Russia under Romanov rule. His poor handling of Bloody Sunday and Russia's role in World War I led to his abdication and execution.  Crowned on May 26, 1894, Nicholas was neither trained nor inclined to rule, which did not help the autocracy he sought to preserve in an era desperate for change. ... In March 1917, the army garrison at Petrograd joined striking workers in demanding socialist reforms, and Czar Nicholas II was forced to abdicate.
