The May Fourth Movement of 1919 was an epochal event in modern Chinese history. It marked the beginning of China's modern revolutionary era, and a new stage after the Republican Revolution of 1911. It was both anti-imperialist and anti-warlord, and represented the reaction of the Chinese people to the turbulent new forces unleashed by the First World War. In specific protest against the terms of the Versailles Peace Treaty as they affected China, and against the terms of Japan's infamous ‘Twenty-one Demands’, huge student demonstrations were held in Peking on 4 May 1919 to denounce the pro-Japanese Peking government. This revolutionary tide soon spread rapidly throughout China, spearheading a rapid growth of mass consciousness and cultural change, and culminating in the founding of the Chinese Communist Party in 1921, in the reorganization of the Kuomintang in 1924, and the establishment of a united front between the Kuomintang and the Chinese Communist Party. It is the very importance of the May Fourth Movement (MFM) as well as its manifold repercussions and ramifications, which have complicated the problems of defining, interpreting, and evaluating the movement per se. The definition of its true nature and character, the clear identification of its actual leadership, and the realistic appraisal of its scope and achievements have all become matters of dispute. Ideological commitment, political ties, or professional interest have too often clouded the objectivity of individuals who have studied the movement—and hence their interpretations of it.
