Chinese nationalism is a form of nationalism that asserts that the Chinese people are a nation and promotes the cultural and national unity of all Chinese people. According to Sun Yat-sen's philosophy in the Three Principles of the People, Chinese nationalism is evaluated as multi-ethnic nationalism, which should be distinguished from Han nationalism or local ethnic nationalism.
Modern Chinese nationalism emerged in the late Qing dynasty (1644–1912) in response to China's humiliating defeat at the end of the First Sino-Japanese War and the invasion and pillaging of Beijing by the Eight-Nation Alliance. In the aftermath of both events, China was forced to pay financial reparations and grant special privileges to foreigners. The nationwide image of China as a superior Celestial Empire, which was located at the center of the universe, was shattered, and last-minute efforts to modernize the old system were unsuccessful. These last-minute efforts were best exemplified by Liang Qichao, a late Qing reformer who failed to reform the Qing government in 1896 and was later expelled from China and fled to Japan, where he began to develop his ideas of Chinese nationalism.
