Engels' Theoretical Contribution to Historical Materialism and its Contemporary Value Implication

As Marx's close comrade-in-arms and revolutionary partner, Engels undertook the major mission of perfecting Marxist philosophy in defense of Marx after Marx's death, but Engels's interpretation of Marxism caused scholars to explore the academic relationship between Marx and Engels, and his book Ludwig Feuerbach and the End of Classical German Philosophy (hereinafter referred to as Engels’Ludwig Feuerbach of 1888) became the focal point of the research on the academic relationship between the two. The work presents Engels' systematic interpretation of the materialist conception of history, his innovative formulation of Engels' theory of historical synergy and the fundamental question of phi-losophy, and is a strong proof of the consistency between the ideas of Marx and Engels. Engels' theoretical contribution to the materialist conception of history in the work still has valuable theoretical value in contemporary times, and inspires us to hold on to Marxism without wavering, and to innovate without stopping, in order to better guide our practice.
