Who is often recognized as the father of communism, known for his analysis of history and beliefs in a classless society?

Karl Marx is recognized as the father of communism primarily due to his foundational role in developing communist theory and his analysis of historical development through the lens of class struggle. His seminal works, particularly "The Communist Manifesto" and "Das Kapital," articulate the idea of historical materialism, which posits that the economic base of society influences its social structure and political institutions. Marx's vision of a classless society arising from the proletariat's overthrow of capitalist systems laid the groundwork for future communist movements. His ideas continue to significantly influence political thought and practice around the world, underscoring his pivotal role in the establishment of communist ideology.
