May Fourth Movement

The May Fourth Movement emerged from student protests in Beijing on 4 May 1919, triggered by news that the Paris Peace Conference had awarded Germany's former concessions in Shandong province to Japan rather than returning them to China. Roughly 3,000 students from Peking University and other institutions gathered at Tiananmen, denounced the Beiyang government's weakness, and attacked the home of Cao Rulin, a minister associated with the pro-Japanese "Twenty-One Demands" of 1915.

The protests rapidly broadened into a nationwide political and cultural awakening. Merchants in Shanghai launched strikes, workers joined boycotts of Japanese goods, and pressure forced the Chinese delegation in Paris, led by Lu Zhengxiang and Wellington Koo, to refuse to sign the Treaty of Versailles in June 1919.

Intellectually, May Fourth is often treated as the political climax of the broader New Culture Movement (c. 1915–1923) associated with figures such as Chen Duxiu, Hu Shi, Li Dazhao, and Lu Xun, and with the journal New Youth (Xin Qingnian). Its slogans championed "Mr. Science" (Sai xiansheng) and "Mr. Democracy" (De xiansheng), promoted vernacular Chinese (baihua) over classical literary style, and attacked Confucian social hierarchies.

The movement reshaped Chinese politics in lasting ways:

• It accelerated the spread of Marxism in China; Li Dazhao and Chen Duxiu went on to help found the Chinese Communist Party in 1921.
• It energised the reorganisation of the Kuomintang under Sun Yat-sen.
• It is widely treated by historians as a foundational moment of modern Chinese nationalism.

Both the People's Republic of China and the Republic of China on Taiwan commemorate 4 May, though with different emphases: the PRC marks it as Youth Day, while the ROC observes it as Literary Day. The movement remains a contested reference point in debates over nationalism, liberalism, and reform in contemporary China.
