On May 4, 1919, patriotic students in Beijing protested the decision at the Paris Peace Conference that Japan should retain defeated Germany’s rights and possessions in Shandong. Many students were arrested in the rioting that followed. Waves of protest spread throughout the major cities of China. Merchants closed their shops, banks suspended business, and workers went on strike to pressure the government. Finally, the government was forced to release the arrested students, to dismiss some officials charged with being tools of Japan, and to refuse to sign the Treaty of Versailles. This outburst helped spread the iconoclastic and reformist ideas of the intellectual movement, which became known as the May Fourth Movement. By the early 1920s, China was launched on a new revolutionary path.

The Nationalist Party

The Nationalist Party had its origins in the earlier United League (Tongmenghui) against the Qing dynasty. The name Nationalist Party was adopted in 1912. After the suppression of this expanded party by Yuan Shikai, elements from it were organized by Sun Yat-sen in 1914 into the Chinese Revolutionary Party, which failed to generate widespread support. Sun and a small group of veterans were stimulated by the patriotic upsurge of 1919 to rejuvenate this political tradition, as well as to revive the Nationalist Party name. The party’s publications took on new life as the editors entered the current debates on what was needed to “save China.” Socialism was popular among Sun’s followers.

The formation of an effective party took several years, however. Sun returned to Guangzhou from Shanghai late in 1920, when Gen. Chen Jiongming (Ch’en Chiung-ming) drove out the Guangxi militarists. Another rump parliament elected Sun president of a new southern regime, which claimed to be the legitimate government of China. In the spring of 1922 Sun attempted to launch a northern campaign as an ally of the Manchurian warlord, Zhang Zuolin (Chang Tso-lin), against the Zhili clique, which by now controlled Beijing. Chen, however, did not want the provincial revenue wasted in internecine wars. One of Chen’s subordinates drove Sun from the presidential residence in Guangzhou on the night of June 15–16, 1922. Sun took refuge with the southern navy, and he retired to Shanghai on August 9. He was able to return to Guangzhou in February 1923 and began to consolidate a base under his own control and to rebuild his party.

The Chinese Communist Party

The CCP grew directly from the May Fourth Movement. Its leaders and early members were professors and students who came to believe that China needed a social revolution and who began to see Soviet Russia as a model. Chinese students in Japan and France had earlier studied socialist doctrines and the ideas of Karl Marx, but the Russian Revolution of 1917 stimulated a fresh interest in keeping with the enthusiasm of the period for radical ideologies. Li Dazhao, the librarian of Peking University, and Chen Duxiu were the CCP’s cofounders.

In March 1920 word reached China of Soviet Russia’s revolutionary foreign policy enunciated in the first Karakhan Manifesto, which promised to give up all special rights gained by tsarist Russia at China’s expense and to return the Russian-owned Chinese Eastern Railway in Manchuria without compensation. The contrast between this promise and the Versailles award to Japan that had touched off the 1919 protest demonstrations could hardly have been more striking. Although the Soviet government later denied such a promise and attempted to regain control of the railway, the impression of this first statement and the generosity still offered in a more diplomatic second Karakhan Manifesto of September 1920 left a favorable image of Soviet foreign policy among Chinese patriots.

Russia set up an international communist organization, the Comintern, in 1919 and sent Grigory N. Voytinsky to China the next year. Voytinsky met Li Dazhao in Beijing and Chen Duxiu in Shanghai, and they organized the Socialist Youth League, laid plans for the Communist Party, and started recruiting young intellectuals. By the spring of 1921 there were about 50 members in various Chinese cities and in Japan, many of them former students who had been active in the 1919 demonstrations. Mao Zedong, a protégé of Li Dazhao, had started one such group in Changsha. The CCP held its First Congress in Shanghai in July 1921, with 12 or 13 attendants and with a Dutch communist—Hendricus Sneevliet, who used his Comintern name, Maring, in China—and a Russian serving as advisers. Maring had become head of a new bureau of the Comintern in China, and he had arrived in Shanghai in June 1921. At the First Congress, Chen Duxiu was chosen to head the party.

The CCP spent the next two years recruiting, publicizing Marxism and the need for a national revolution directed against foreign imperialism and Chinese militarism, and organizing unions among railway and factory workers. Maring was instrumental in bringing the KMT and the CCP together in a national revolutionary movement. A number of young men were sent to Russia for training. Among the CCP members were many students who had worked and studied in France, where they had gained experience in the French labor movement and with the French Communist Party; Zhou Enlai was one of these. Other recruits were students influenced by the Japanese socialist movement. By 1923 the party had some 300 members, with perhaps 3,000 to 4,000 in the ancillary Socialist Youth League.
