Over the course of WWI, Russia endured major losses and was subject to extreme poverty and high inflation. The Russian public blamed Nicholas II for his poor military decisions, and Empress Alexandra for her ill-advised role in government. Because Alexandra was originally from Germany, suspicion spread that she might have even deliberately sabotaged Russia, ensuring its defeat in the war.
By February of 1917, Nicholas II’s subjects were in such an uproar that riots broke out in St. Petersburg. Nicholas was still headquartered at Mogilev at the time. When he tried to get home to Petrograd, the Duma, who had by then turned on him, prevented him from boarding the train. After the Duma elected their own provisional committee built of progressive bloc members, and the soldiers sent to quash the St. Petersburg riots mutinied, Nicholas II had no other choice but to step down from the monarchy. On March 15, 1917 he abdicated the throne. He and his family were then taken to the Ural Mountains and placed under house arrest.
