The revolutionary science of the working class — study it, apply it, advance it
Marxism-Leninism is not a set of abstract ideas — it is a guide to action. Whether you are encountering these ideas for the first time or deepening your understanding, this page provides the theoretical foundations. New to Marxism-Leninism? Start with What is Marxism-Leninism? for a beginner-friendly introduction.
Begin with materialist philosophy — the bedrock upon which everything else is built.
Political economy reveals how exploitation operates and why capitalism produces crises.
Scientific socialism answers the question: what is to be done?
Theory without practice is sterile. Connect your study to real-world struggle.
Marxism-Leninism is the science of revolution. It is composed of three integral parts: materialist philosophy, political economy, and scientific socialism. Together, they provide the working class with the theoretical tools necessary to understand the world and change it.
These three components are not separate disciplines — they form a unified whole. Philosophy provides the method of analysis. Political economy applies that method to the study of capitalism. Scientific socialism draws the practical-political conclusions: how the working class organises to overthrow capitalism and build a new society.
Matter is primary, consciousness is secondary. The material world exists independently of our perception. All phenomena — including thought, society, and history — are products of material processes. There is no God, no soul, no supernatural realm. The universe is physical and knowable through science.
EconomicsMarx demonstrated that the capitalist mode of production is based on the exploitation of wage labour. The worker produces more value than they receive in wages — the surplus is appropriated by the capitalist as profit. This is not a moral failing but a structural feature of capitalism that can only be resolved by abolishing private ownership of the means of production.
PoliticsThe class struggle between the bourgeoisie and the proletariat is the driving force of modern history. The working class, through revolutionary organisation, must seize state power and establish the dictatorship of the proletariat — a workers' state that suppresses the former exploiters and builds the material foundations of communism.
Historical materialism is the application of materialist philosophy to the study of society. It holds that the mode of production — how a society organises its economic life — determines the character of its social, political, legal, and ideological superstructure.
History moves through stages defined by the dominant mode of production: primitive communism, slavery, feudalism, capitalism, and socialism leading to communism. Each stage develops productive forces to their limit, at which point the existing relations of production become a fetter on further development, and social revolution becomes inevitable.
The transition from capitalism to socialism is not a utopian dream but a historical necessity arising from the contradictions within capitalism itself — the socialisation of production versus the private appropriation of surplus value.
The base (economic relations of production) determines the superstructure (politics, law, religion, culture). When the base changes, the superstructure eventually changes with it — though not mechanically, and not without struggle.
"It is not the consciousness of men that determines their being, but, on the contrary, their social being that determines their consciousness."
— Karl Marx, Preface to A Contribution to the Critique of Political Economy (1859)The state is not a neutral arbiter above classes. It is an instrument of class rule — the organised power of one class for the suppression of another. The capitalist state, with its police, army, courts, and prisons, exists to protect the property and power of the bourgeoisie.
The working class cannot simply take over the existing state machinery and use it for its own purposes. The bourgeois state must be smashed and replaced by a new type of state — the dictatorship of the proletariat — which represents the organised power of the working class majority over the former exploiting minority.
As classes are abolished and the material conditions for exploitation disappear, the state itself withers away, giving rise to the classless, stateless society of communism.
The dictatorship of the proletariat is not one-man rule — it is workers' democracy, the rule of the majority over the former exploiting minority. Compare this with the current dictatorship of the bourgeoisie, where a tiny capitalist class rules over billions through parliamentary illusion.
Lenin identified imperialism as the highest stage of capitalism, characterised by the dominance of finance capital, the export of capital, the division of the world among monopoly capitalist groups, and the territorial division of the world among the great powers.
Imperialism produces war, colonial oppression, and the super-exploitation of the peoples of the oppressed nations. It also creates the conditions for socialist revolution by sharpening all the contradictions of capitalism to their extreme.
Today, NATO imperialism — led by the United States, Britain, and France — continues to wage wars of aggression, maintain neo-colonial control over Africa, Asia, and Latin America, and threaten any nation that dares to chart an independent course.
Lenin identified five features of imperialism: (1) concentration of production into monopolies, (2) merging of bank and industrial capital into finance capital, (3) export of capital, (4) formation of international monopoly combines, (5) territorial division of the world among the great powers.
"Without revolutionary theory there can be no revolutionary movement."
— V. I. Lenin, What Is To Be Done? (1902)We are strict materialists. We reject Hegelian idealism and the mystification of dialectics. The world is physical, governed by natural laws, and knowable through the methods of science. There is no room in Marxism-Leninism for mysticism, spirituality, or any form of idealism.
Consciousness is a product of the material organisation of the brain — it is computation. There is no soul, no afterlife, no divine purpose. Human beings are physical systems, and human society is a material phenomenon subject to scientific analysis.
This is not nihilism — it is liberation. When we understand the material laws governing society, we can consciously direct social development for the benefit of the working class and all humanity.
Theory separated from practice becomes empty scholasticism. Practice without theory becomes blind improvisation. The unity of theory and practice is the hallmark of Marxism-Leninism.
Every section of theory on this site connects to concrete struggle. Understanding political economy explains why wages stagnate while billionaires multiply. Understanding the state explains why parliament cannot deliver socialism. Understanding imperialism explains why NATO bombs Libya while lecturing about human rights.

The theoretical contributions of these revolutionary leaders form the foundation of Marxism-Leninism.
Every theoretical principle finds expression in concrete struggle. Here are examples of Marxist-Leninist theory applied to today's crises.
Surplus value extracted from workers is reinvested in property speculation, driving rents beyond reach. Political economy explains why housing cannot be fixed under capitalism.
