Marx first promoted the theoretical process of the concretization of Historical Materialism in The Class Struggles in France 1848 to 1850 and The Eighteenth Brumaire of Louis Bonaparte . He completed this theoretical work by deepening the external manifestations of the internal contradictions of the mode of production under specific conditions and raising the research on the history of political struggle to the level of the historical law of political development. Marx?s theoretical exploration not only enabled him to realize the innovative leap of methodology and theoretical achievements in the research of French political history but also set an example for the latecomers in the discussion of the concretization of Historical Materialism. Deepening the theoretical interpretation of Marx?s exploration in this area not only helps promote the study of the history of Marxist philosophy but also inspires us to understand better the great achievements of socialism with Chinese characteristics.
