/kloc-The Second Opium War, which began in 0/856, and a series of unequal treaties, such as the Tianjin Treaty and the Beijing Treaty, which were subsequently signed, accelerated the historical process of the semi-colonial and semi-feudal evolution of China society.
1894 Sino-Japanese War of 1894 (1894) and the subsequent signing of treaty of shimonoseki further deepened the semi-colonial and semi-feudal degree of China.
1900 Eight-Nation Alliance's war of aggression against China and the signing of the treaty of shame and ugliness the following year completely made the Qing government a tool for imperialism to control China, marking the basic formation of a semi-colonial and semi-feudal society in China.
In this humiliating historical process, western powers forced China to sign one unequal treaty after another through a series of brutal military aggression and war threats, which made China society change twice:
On the one hand, with the gradual deepening of foreign powers' aggression, China has changed from a feudal country with territorial integrity and sovereign independence to a semi-colonial country with formal independence but actually controlled by imperialist powers.
On the other hand, due to the invasion of foreign capitalism, China's original feudal economic structure, which lasted for thousands of years, was greatly disintegrated. Emerging national capitalism developed initially in China, and China changed from a completely feudal society to a semi-feudal society with some capitalist elements.
