Libertarian Marxism is often critical of reformist positions such as those held by social democrats. Libertarian Marxist currents often draw from Karl Marx and Friedrich Engels' later works, specifically the "Grundrisse" and "The Civil War in France"; emphasizing the Marxist belief in the ability of the working class to forge its own destiny without the need for a state or vanguard party to mediate or aid its liberation. Along with anarchism, libertarian Marxism is one of the main currents of libertarian socialism.
