Russia: 'Everything for the war, war loan at 5.5 percent'. Russian World War I propaganda poster, 1916

World War One was to have a devastating impact on Russia. When World War One started in August 1914, Russia responded by patriotically rallying around Nicholas II. Military disasters at the Masurian Lakes and Tannenburg greatly weakened the Russian Army in the initial phases of the war. The growing influence of Gregory Rasputin over the RomanovÕs did a great deal to damage the royal family and by the end of the spring of 1917, the Romanovs, who had ruled Russia for just over 300 years, were no longer in charge of a Russia that had been taken over by Kerensky and the Provisional Government. By the end of 1917, the Bolsheviks led by Lenin had taken power in the major cities of Russia and introduced communist rule in those areas it controlled. The transition in Russia over the space of four years was remarkable Ð the fall of an autocracy and the establishment of the worldÕs first communist government.
