How did Marx adapt Hegel's dialectical method?

Karl Marx adapted the dialectical method of G.W.F. Hegel by shifting its focus from idealism to materialism.12

While Hegel viewed the dialectic as the self-development of "spirit" or the "Idea," Marx argued that this approach was mystifying and inverted the true relationship between reality and thought. Marx rejected the notion that history is driven by the realization of a world spirit, asserting instead that change is inherent in the material world. He maintained that material conditions—specifically the economic and social relations of production—drive historical development.132

Furthermore, Marx criticized Hegel for attempting to deduce the course of events from abstract dialectical principles. Marx insisted that such principles must be inferred from actual historical events. By grounding the dialectic in material reality rather than abstract thought, Marx transformed it into a tool for analyzing the class struggles and contradictions that define human society.12
