It was based on the principles of Marxism-Leninism, emphasizing a one-party state led by the Communist Party. The government aimed to create a classless society through state control of the economy and collective ownership of resources. The structure of the Soviet Government included various institutions, such as the Supreme Soviet, which served as the legislative body. Key leaders, like Vladimir Lenin and later Joseph Stalin, played significant roles in shaping policies and governance. The system was characterized by centralized authority and limited political freedoms.
