"The Communist Manifesto" was co-authored by Karl Marx and Friedrich Engels in 1848. This influential political document outlines the theories of class struggle, the problems of capitalism, and the call for a proletarian revolution. Marx and Engels argued that societies progress through conflicts between the ruling class, the bourgeoisie, and the working class, the proletariat. The manifesto emphasized the need for workers to unite and overthrow oppressive structures to establish a classless society. Its profound impact has resonated throughout political thought and movements across the world.
