The Main Content and Character of Marx's World History Theory

In The Grundrisse, Marx expressed his world history theory firstly, and then he further described it in German Ideology and Communist Manifesto in a systematic way. According to his criticism to Hegel's world history theory, Marx posed his own world history theory by materialism in order to analyze and understand the phenomena and problems of capitalistic society. In my opinion, the essence of Marx's world history theory is the following: As the result of capitalistic industry, although world history is the necessary trend of the development of human history, it is not the final form of the development of human society yet, but is the basic presupposition of the realization of communism.
