Historical materialism

This relationship is reflexive in that the base initially gives rise to the superstructure and remains the foundation of a form of social organisation. Those newly formed social organisations can then act again upon both parts of the base and superstructure so that rather than being static, the relationship is dialectic, expressed and driven by conflicts and contradictions. Engels clarified: "The history of all hitherto existing society is the history of class struggles. Freeman and slave, patrician and plebeian, lord and serf, guild -master and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary reconstitution of society at large, or in the common ruin of the contending classes."
