Marx’s Methodology

Karl Marx's a figure in philosophy, sociology and economics established an approach to understanding society and History through his methodology. He developed two main major methodologies: 

• Historical Materialism  
• Dialectical Materialism

These methodologies contained the Materialist and Dialectical philosophies which are used to describe the interplay of economic forces, social classes, and historical changes. Historical Materialism describes the social change that is primarily driven by changes in material conditions of production. And Dialectical Materialism derived from Hegelian Dialectics, describes the role of conflict and contradiction within the material world, particularly within the economic and social world.
