Marxism is a political philosophy and method of socioeconomic analysis. It uses a materialist interpretation of historical development, better known as "historical materialism," to understand class relations and social conflict. It also uses a dialectical perspective to view social transformation. Marxism originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels. Marxism has developed over time into various branches and schools of thought, As a result, there is no single, definitive Marxist theory. Marxism has had a profound impact in shaping the modern world, with various left-wing and far-left political movements taking inspiration from it in varying local contexts.
