Answer with Explanation:
The "intelligentsia" was a social class or status of highly-educated people who had a common interest of shaping the society's politics and culture. Unlike "intellectuals," the intelligentsia were dedicated to their goals of spreading a particular attitude in people's way of life.
In the middle of the 9th century, "socialism" according to Marx and Engels which was designed in Germany and France arrived in Russia. Such theory believes in the end of class struggles through "full communism." This immediately attracted the "Russian revolutionary intelligentsia." One of these was Vladimir Lenin, who became one of the dedicated and convinced Marxists. He started to organize a rebellious group called the "Bolsheviks." This group was an advocated on a "classless society" which provided different decrees such as a decree on land, peace, etc. and the rights of the Russian people.
People who supported him also supported Communism because they'd rather have control of their own production in the country without the interference of the government. He then became Russia's head and the Soviet Union's head. Under his rule, the Soviet Union became a one-party communist state. He then developed "Leninism," which was another version of Marxism.
