What events led to the decline of the Chinese Nationalists?

May Fourth Movement, intellectual revolution and sociopolitical reform movement that occurred in China in 1917-21. The movement was directed toward national independence, emancipation of the individual, and rebuilding society and culture.

In 1915, in the face of Japanese encroachment on China, young intellectuals, inspired by "New Youth" (Xin qingnian), a monthly magazine edited by the iconoclastic intellectual revolutionary Chen Duxiu, began agitating for the reform and strengthening of Chinese society. As part of this New Culture Movement, they attacked traditional Confucian ideas and exalted Western ideas, particularly science and democracy. Their inquiry into liberalism, pragmatism, nationalism, anarchism, and socialism provided a basis from which to criticize traditional Chinese ethics, philosophy, religion, and social and political institutions. Moreover, led by Chen and the American-educated scholar Hu Shi, they proposed a new naturalistic vernacular writing style (baihua), replacing the difficult 2,000-year-old classical style (wenyan).

These patriotic feelings and the zeal for reform culminated in an incident on May 4, 1919, from which the movement took its name. On that day, more than 3,000 students from 13 colleges in Beijing held a mass demonstration against the decision of the Versailles Peace Conference, which drew up the treaty officially ending World War I, to transfer the former German concessions in Shandong province to Japan. The Chinese government’s acquiescence to the decision so enraged the students that they burned the house of the minister of communications and assaulted China’s minister to Japan, both pro-Japanese officials. Over the following weeks, demonstrations occurred throughout the country; several students died or were wounded in these incidents, and more than 1,000 were arrested. In the big cities, strikes and boycotts against Japanese goods were begun by the students and lasted more than two months. For one week, beginning June 5, merchants and workers in Shanghai and other cities went on strike in support of the students. Faced with this growing tide of unfavourable public opinion, the government acquiesced; three pro-Japanese officials were dismissed, the cabinet resigned, and China refused to sign the peace treaty with Germany.

As a part of this movement, a campaign had been undertaken to reach the common people; mass meetings were held throughout the country, and more than 400 new publications were begun to spread the new thought. As a result, the decline of traditional ethics and the family system was accelerated, the emancipation of women gathered momentum, a vernacular literature emerged, and the modernized intelligentsia became a major factor in China’s subsequent political developments. The movement also spurred the successful reorganization of the Nationalist Party (Kuomintang), later ruled by Chiang Kai-shek (Jiang Jieshi), and stimulated the birth of the Chinese Communist Party as well.

Nationalist Party, also called Kuomintang, Wade-Giles romanization Kuo-min Tang (KMT; "National People’s Party"), political party that governed all or part of mainland China from 1928 to 1949 and subsequently ruled Taiwan under Chiang Kai-shek and his successors for most of the time since then.

Originally a revolutionary league working for the overthrow of the Chinese monarchy, the Nationalists became a political party in the first year of the Chinese republic (1912).
