The debacle of the Kuomintang regime in Mainland China in 1949 showed that the political course pursued by Chiang Kai-shek had completely failed to meet the challenges of the time. Since then there has been much speculation on whether the Kuomintang regime would have survived in China if a different political course had been pursued by the party. This kind of curiosity has now drawn historians’ attention to the Kuomin tang Left, which during 1928-31 had initiated an opposition movement against Chiang Kai-shek’s regime in Nanking; it had expounded its own ideological stand and offered an alternative programme to the official policy line. This thesis is a study of the opposition movement of the Kuomintang Left in 1928-31 and attempts to answer the question of whether the Kuomintang Left had propounded a viable alternative to Chiang’s course within the political context of the time.

The opposition movement led by the Kuomintang Left started in late 1928 when the Leftist leadership was displaced from the Party Central in Nanking and its positions in the party at regional level were being challenged. The Leftist opposition movement against Nanking can be divided into two important phases. The first phase began with the “Party-Defending and National Salvation Movement” in mid-1929 and culminated in the Enlarged Party Conference in Peiping in July 1930. The second phase started with the summoning of the Extraordinary Party Conference in Canton in May 1931 and ended with the beginning of the “Wang-Chiang cooperation” in January 1932. In these two phases of opposition movement, the Kuomintang Left not only had obtained support from other opposition groups in the party but, more importantly, also had secured al liances with major regional militarists who launched several large-scale military cam paigns against Nanking. In the end the opposition movement failed to bring down Chiang Kai-shek’s regime in Nanking; ironically its only notable result was to usher in an era of “Wang-Chiang cooperation” in the Nanking regime which on the whole lasted until Wang’s defection to the Japanese side during the Sino-Japanese War.

The detailed investigation into the Leftist opposition movement during 1928-31 has led this study to conclude that the Leftist alternative was not viable within the political context of the time. In the first place, the quality of the Leftist leadership left much to be desired. There were remarkable differences in ideological orientation at the top level of the leadership and a lack of firm political will was evident among Leftist leaders. In particular, Wang Ching-wei’s ever readiness to make compromises in the long run had undermined the Leftist appeal to the party’s rank and file and to the masses in general. Furthermore, though for a time the Left did enlist significant support of the party’s ranks and build a constituency among certain sections of the population, its strength in the party could not withstand the onslaught from the Nanking Govern ment and its social constituency was at most marginal. Eventually Wang Ching-wei decided to end the Leftist opposition movement and came to terms with Chiang Kai- shek shortly after the Manchurian Incident. An absence of leadership and inadequate political strength of the Kuomintang Left rendered the Leftist alternative not viable in Chinese Republican history.
