So The history of Soviet Russia and the Soviet Union reflects a period of change for both Russia and the world. Though the terms Soviet Russia and Soviet Union are synonymous in everyday vocabulary, when we talk about the foundations of the Soviet Union, Soviet Russia refers to the few years after the abdication of the crown of the Russian Empire by Tsar Nicholas II (in 1917), but before the creation of the Soviet Union in 1922. Early in its conception, the Soviet Union strived to achieve harmony among all peoples of all countries. The original ideology of the state was primarily based on the works of Karl Marx and Friedrich Engels. In its essence, Marx's theory stated that economic and political systems went through an inevitable evolution in form, by which the current capitalist systemwould be replaced by a socialist state before achieving international cooperation and peace in a "Workers' Paradise," creating a system directed by what Marx called "Pure Communism."
Displeased by the relatively few changes made by the Tsar after the Revolution of 1905, Russia became a hotbed of anarchism, socialism and other radical political systems. The dominant socialist party, the Russian Social Democratic Labour Party (RSDLP), subscribed to Marxist ideology. Starting in 1903, a series of splits in the party between two main leaders was escalating: the Bolsheviks(meaning "majority") led by Vladimir Lenin, and the Mensheviks (meaning "minority") led by Julius Martov. Up until 1912, both groups continued to stay united under the name "RSDLP," but significant and irreconcilable differences between Lenin and Martov led the party to eventually split. A struggle for political dominance subsequently began between the Mensheviks and the Bolsheviks. Not only did these groups fight with each other, but they also had common enemies, notably, those trying to bring the Tsar back to power. Following the February Revolution in 1917, the Mensheviks gained control of Russia and established a provisional government, but this lasted only until the Bolsheviks took power in the October Revolution (also called the Bolshevik Revolution) later in the year. To distinguish themselves from other socialist parties, the Bolshevik party was renamed the Russian Communist Party (RCP).
Under the control of the party, all politics and attitudes that were not strictly RCP were suppressed, under the premise that the RCP represented the proletariat and all activities contrary to the party's beliefs were "counterrevolutionary" or "anti-socialist." During the years between 1917 and 1923, the Soviet Union achieved peace with the Central Powers, their enemies in World War I, but also fought the Russian Civil War against the White Army and foreign armies from the United States, the United Kingdom, and France, among others. This resulted in large territorial changes, albeit temporarily for some of these. Eventually crushing all opponents, the RCP spread Soviet style rule quickly and established itself through all of Russia. Following Lenin's death in 1924, Joseph Stalin, General Secretary of the RCP, became the de facto leader of the USSR. I just know this because I study this before
