Their most influential work, "The Communist Manifesto," co-written in 1848, outlines the struggles between social classes and presents the idea of a classless society as a goal. They analyze the impacts of capitalism on workers and call for collective action to overthrow bourgeois dominance. Their ideas laid the groundwork for modern socialist movements around the world.
