In the early Qing Dynasty, in order to alleviate class contradictions and implement the policy of rewarding land reclamation and reducing taxes, the social economy of the mainland and frontier areas developed to some extent. By the middle of18th century, the feudal economy had reached a new peak, which was called "the prosperous time of Kang Yong". In this way, the centralized autocratic system is more rigorous, with strong national strength and stable order. By the end of the 18th century, the population of Qing Dynasty had reached about 300 million. During the reign of Emperor Kangxi, Taiwan Province Province was unified, and the Sino-Russian Nebuchadnezzar Chu Treaty was signed with Russia, which demarcated the eastern border between China and Russia. In the middle of Qianlong period, Junggar and Uighur were pacified and Xinjiang was unified. This not only solved the long-standing contradiction between nomadic people and agricultural people in the history of China, but also adopted a series of policies to develop the economy, culture and transportation in the border areas, consolidated the unity of China's multi-ethnic countries, laid the territory of modern China, and enhanced the unity and cohesion of the Chinese nation. The largest territory of the Qing Dynasty was over120,000 square kilometers. Its territory started from Balkhash Lake and Qinling Mountains in the west, the Sea of Okhotsk and Sakhalin Island in the northeast, the sea area including Taiwan Province Province and its affiliated islands in the east, the South China Sea Islands in the south, Guangxi, Yunnan and Dalac in the southwest, and Mobei and Waixing 'an Mountains in the north. Culturally, during the period of Kanggan, several famous books were compiled, such as Sikuquanshu and Integration of Ancient and Modern Books, which made great contributions to clearing up and summarizing China's historical and cultural heritage.
Although the Qing Dynasty made these remarkable achievements, its development did not go beyond the track of China's traditional feudal autocracy. Economically, this country is still based on agriculture; In cultural thought, he advocated feudal ethics and morality, and repeatedly pushed the literary inquisition; In foreign relations, he has been closed to the outside world for a long time and is blind and arrogant. Therefore, compared with the prosperous times of western capitalism in the same period, these achievements made in the late feudal society of China are dwarfed. China has fallen behind the advanced trend of world development and is pulling away.
After the mid-Qing Dynasty, due to the long history, various social contradictions became increasingly exposed, and anti-Qing struggles broke out one after another. The Anbaili Uprising, which lasted for nine years, ended the heyday of the Qing Dynasty. 1840 After the Opium War and the imperialist invasion, the Qing court and the invaders respectively concluded a series of unequal treaties, ceded land for compensation and opened trading ports, and China gradually became a semi-feudal and semi-colonial society. China was badly damaged, and the Manchu lost its early enterprising spirit, became corrupt, rigid, cowardly and inferior politically, and stumbled into recession. The people's burden is heavier and they are in dire straits, so a series of anti-imperialist and anti-feudal movements such as the Taiping Heavenly Kingdom Movement and the Nian Army Uprising broke out. In order to save their own destiny, the ruling class also carried out some reform activities, such as the Westernization Movement.
The Movement and the Reform Movement of 1898 tried to make China embark on the road of prosperity and independence through top-down changes, but both ended in failure. Countless people with lofty ideals fought bloody battles to save the nation from peril. The wave of patriotism is surging in the modern history of China. 19 1 1 year, the Revolution of 1911 broke out and the Qing Dynasty was overthrown, thus ending the feudal monarchy in China for more than two thousand years, and the history of China entered a new chapter. After the Qing dynasty entered the customs, it went through ten emperors for 268 years.
