Final answer:
Karl Marx disagreed with Hegel on the driving force behind historical change. While Hegel believed in conflicts of ideas, Marx argued that societies change through struggles between social classes over the means of production.
Step-by-step explanation:
Karl Marx disagreed with Georg Wilhelm Friedrich Hegel on the issue of the driving force behind historical change. While Hegel believed that history progressed through conflicts of ideas, Marx argued that societies grew and changed as a result of the struggles of different social classes over the means of production.
Marx's dialectical materialism emphasized economic conflicts between social classes as the driving force of change, particularly the conflict between the bourgeoisie (owners of the means of production) and the proletariat (workers).
