After Britain opened the locked door to China from 65438 to 0840, it became the fat meat for countries to compete for colonies. After two Opium Wars, the Sino-French War, the Sino-Japanese War and Eight-Nation Alliance's invasion of China, a series of unequal treaties were signed. China was forced into the world market and became a semi-colonial and semi-feudal society. The people of China were miserable and the national crisis intensified. The oppressed peasants in China launched the Taiping Heavenly Kingdom Movement. Although the uprising failed, foreign aggression made China's advanced people aware of the gap between China and the world. China is no longer a big country in China. Lin Zexu, Humen and Wei Yuan, aiming at resisting foreign aggression and seeking national independence and self-improvement, opened their horizons to the world and explored and learned from the West, which gradually became the mainstream of China's modern thoughts. The Westernization School advocated "using Chinese culture for western purposes" and put it into action to set up military industry and civilian industry, thus opening the modernization of China. The Boxer Rebellion, which started at the end of 19, hit the arrogance of imperialism and promoted the Reform Movement in Qing Dynasty to some extent. Reform thinkers advocated new learning, advocated civil rights and formulated the constitution; From imitating western guns to learning western political system, it has become a new idea to save the country; Since the 20th century, the Revolution of 1911 led by Sun Yat-sen overthrew the imperial system and the May 4th New Culture Movement, held high the banner of democracy and science, profoundly inspired the consciousness of the people of China, and was the beginning of the new-democratic revolution. Since then, the spread of Marxist thought has injected new hope into China, and the birth of the China * * * Production Party has pointed out the way for China. After the blood sacrifice of a generation of revolutionary predecessors, China finally won the victory in War of Resistance against Japanese Aggression.
