Soviet communism was a political and economic system that emerged in the early 20th century, primarily under the leadership of Vladimir Lenin and later Joseph Stalin. It aimed to create a classless society by abolishing private property and establishing state control over the economy. The government managed all industries and resources, promoting the idea of collective ownership. The system was characterized by a single-party rule, where the Communist Party held all political power. While it sought to eliminate social inequalities, it often led to authoritarian governance, censorship, and repression of dissent. The Soviet Union, which lasted from 1922 until its dissolution in 1991, was the most prominent example of this ideology in practice.
