Socialist movements are political and social efforts aimed at promoting social ownership and democratic control of the means of production. These movements advocate for policies that reduce economic inequality and provide basic needs, such as healthcare and education, to all citizens. They often seek to challenge capitalist systems and promote workers' rights. Historically, socialist movements have taken various forms, including democratic socialism, Marxism, and anarcho-socialism. Key figures in these movements include Karl Marx, whose ideas laid the foundation for many socialist theories, and Vladimir Lenin, who led the Bolshevik Revolution in Russia. These movements have influenced numerous political parties and governments worldwide.
