Nicholas's successor Alexander II (1855–1881) was forced to undertake a series of comprehensive reforms and issued a decree abolishing serfdom in 1861. The Great Reforms of Alexander's reign spurred increasingly rapid capitalist development and Sergei Witte's attempts at industrialization. The Slavophile mood was on the rise, spearheaded by Russia's victory in the Russo-Turkish War, which forced the Ottoman Empire to recognize the independence of Romania, Serbia and Montenegro and autonomy of Bulgaria. The failure of agrarian reforms and suppression of the growing liberal intelligentsia were continuing problems however, and on the eve of World War I, the position of Tsar Nicholas II and his dynasty appeared precarious. Repeated devastating defeats of the Russian army in the Russo-Japanese War and World War I, and the consequent deterioration of the economy led to widespread rioting in the major cities of the Russian Empire, and ultimately to the overthrow of the Tsar in February 1917.
At the close of this Russian Revolution of 1917, a Marxist political faction called the Bolsheviks seized power in Petrograd and Moscow under the leadership of Vladimir Lenin. The Bolsheviks changed their name to the Communist Party. A bloody civil war ensued, pitting the Bolsheviks' Red Army against a loose confederation of anti-socialist monarchist and bourgeois forces known as the White Army. The Red Army triumphed, and the Soviet Union was formed in 1922.

Main articles: History of the Soviet Union and Russian SFSR The Soviet Union was meant to be a trans-national worker's state free from nationalism. The concept of Russia as a separate national entity was therefore not emphasized in the early Soviet Union. Although Russian institutions and cities certainly remained dominant, many non-Russians participated in the new government at all levels.
