The division of modern history is mainly determined by China's social contradictions;
1, the contradiction between foreign capitalism and the Chinese nation, feudalism and the masses, and the former is the most important contradiction.
2. However, in the course of history, these two contradictions show a complicated and ups and downs relationship. The two contradictions stipulate that the historical theme of modern China is to overthrow foreign capital-imperialism, get rid of the rule and oppression of feudalism and bureaucratic capitalism, and strive for national liberation, national prosperity, social progress and people's happiness.
3. The fundamental task of modern China is to completely oppose imperialism and feudalism, realize national modernization and change the semi-colonial and semi-feudal social nature of modern China.
