world war 1

Main article: Russian Revolution of 1917
Dissatisfaction with the Russian government's conduct of the war grew, despite the success of the June 1916 Brusilov offensive in eastern Galicia. The success was undermined by the reluctance of other generals to commit their forces to support the victory. Allied and Russian forces revived only temporarily with Romania's entry into the war on 27 August. German forces came to the aid of embattled Austrian units in Transylvania and Bucharest fell to the Central Powers on 6 December. Meanwhile, unrest grew in Russia, as the Tsar remained at the front. Empress Alexandra's increasingly incompetent rule drew protests and resulted in the murder of her favourite, Rasputin, at the end of 1916.


Vladimir Illyich LeninIn March 1917, demonstrations in St Petersburg culminated in the abdication of Tsar Nicholas II and the appointment of a weak Provisional Government. It shared power with the socialists of the Petrograd Soviet. This arrangement led to confusion and chaos both at the front and at home. The army became increasingly ineffective.

The war and the government became more and more unpopular. Discontent led to a rise in popularity of the Bolshevik party, led by Vladimir Lenin. He promised to pull Russia out of the war and was able to gain power. The triumph of the Bolsheviks in November was followed in December by an armistice and negotiations with Germany. At first, the Bolsheviks refused to agree to the harsh German terms. But when Germany resumed the war and marched with impunity across Ukraine, the new government acceded to the Treaty of Brest-Litovsk on 3 March 1918. It took Russia out of the war and ceded vast territories, including Finland, the Baltic provinces, parts of Poland and Ukraine to the Central Powers.

The publication by the new Bolshevik government of the secret treaties signed by the Tsar was hailed across the world, either as a great step forward for the respect of the will of the people, or as a dreadful catastrophe which could destabilise the world. The existence of a new type of government in Russia led to the reinforcement in many countries of Communist parties.

After the Russians dropped out of the war, the Entente no longer existed. The Allied powers led a small-scale invasion of Russia. The intent was primarily to stop Germany from exploiting Russian resources and, to a lesser extent, to support the Whites in the Russian Civil War. Troops landed in Archangel (see North Russia Campaign) and in Vladivostok.
