The influential political theory that emerged from the writings of Karl Marx and Friedrich Engels is known as Marxism. This theory critiques capitalism, advocating for a classless society achieved through revolution. Marx and Engels argued that the proletariat, or working class, would eventually rise against the bourgeoisie, or capitalist class, to dismantle oppressive economic structures. Their seminal work, the Communist Manifesto, inspired numerous political movements and revolutions worldwide, with lasting impacts on social and political thought. Marxism continues to shape debates about class struggle, economic inequality, and social justice.
