After the Russian Revolution, the Soviet Union adopted communism, a system that sought to promote the establishment of an egalitarian society without social classes.

Explanation:

The Russian Revolution of 1917 was a series of political events in Russia, which, after the elimination of the Russian autocracy and after the Provisional Government, resulted in the establishment of Soviet power under the control of the Bolshevik party (which later changed its name to Communist Party of Soviet Union). The result of this process was the creation of the Soviet Union, which lasted until 1991.

Communism is a political and socioeconomic ideology, which seeks to promote the establishment of an egalitarian society, without social classes and stateless, based on the common ownership of the means of production.
