First United Front

The First United Front (alternatively ), also known as the KMT–CCP Alliance, of the Kuomintang (KMT) and the Chinese Communist Party (CCP), was formed in 1924 as an alliance to end warlordism in China. Together they formed the National Revolutionary Army and set out in 1926 on the Northern Expedition. The CCP joined the KMT as individuals, making use of KMT's superiority in numbers to help spread communism. The KMT, on the other hand, wanted to control the communists from within. Both parties had their own aims and the Front was unsustainable. In 1927, KMT leader Chiang Kai-shek purged the Communists from the Front while the Northern Expedition was still half-complete. This initiated a civil war between the two parties that lasted until the Second United Front was formed in 1936 to prepare for the coming Second Sino-Japanese War.

Impact of the Russian Revolution
Although its significance was not at first fully recognized by Chinese observers, the October Revolution would eventually have a profound effect on China. Sun Yat-sen and the Kuomintang's reaction to the news was immediately positive. Sun Yat-sen called Vladimir Lenin a "great man", and indicated he wished to follow the same path that Lenin had. However, this was unusual. It took other Chinese radicals such as Chen Duxiu and Li Dazhao until after the end of World War I for them to appreciate the Bolsheviks' radical departure from the February Revolution. By early 1920, however, they had become convinced of the efficacy of this new revolutionary and political model and were moving towards founding the CCP.

The foreign policy of the new Soviet Union towards China was likewise extremely significant. According to orthodox Marxist theory, countries like China lacked the material conditions (such as a large proletariat) to successfully transition to socialism. However, Lenin argued in Imperialism, the Highest Stage of Capitalism, that capitalism in the early twentieth century had become dependent on imperialist exploitation of the third world. Anti-imperialist movements had the potential of destabilizing the worldwide capitalist system and in that way could hasten the revolution where material conditions were right. Thus, the early Soviet position on China was opposed to socialist revolution—in the Sun-Joffe Manifesto, they formally agreed that China was not ready for "the Soviet system". But they sought to encourage an anti-imperialist movement that included both "bourgeois nationalists" and the working class. The Sun-Joffe Manifesto began a period of extensive aid to Sun Yat-sen and his movement. Soviet advisors helped Sun reorganize the Kuomintang along Leninist lines, making the party significantly more effective. They founded the Whampoa military academy as well as a civil university to educate KMT cadres.

The resurrection of Kuomintang
During the time of warlords, Sun Yat-sen kept the idea of a united Chinese republic alive. His goal was to establish a rival government in Guangzhou, southern China, and go from there to fight against the warlords in the North and their Beiyang government. Upon his return from exile in 1917, Sun revived his banned nationalist party, the Kuomintang, but this time he gave it the new name, the Kuomintang of China. His plan was that after defeating the warlords the party would guide China until the country would be ready to move to democracy.

The rival government led by Sun, however, was at a disadvantage against the warlords from a military point of view. Despite his requests for aid from the West, badly needed financial and arms support never arrived in the country. In the 1920s the Kuomintang eventually received help from the Russian Bolsheviks. Material aid from Russia was good enough for Sun, who had previously shown flexibility when the question was about the promotion of the republic. He had neither sympathy towards Marxism nor did he see communism as a solution to China's problems. In Sun's view, China was not of the rich and the poor; rather, it was the country of the poor and the poorer. The guidelines of the Kuomintang were based on Sun's "Three Principles of the People": nationalism, democracy and the people's livelihood (socialism).

The Kuomintang gradually became a powerful and disciplined party under Russian guidance. The decisive factor was the Bolshevik's assistance to the Kuomintang in the formation of its own army, the National Revolutionary Army. In order to train the army the Whampoa Military Academy was established near Guangzhou. As its director, Sun appointed his loyal supporter Chiang Kai-shek. Financially the Whampoa Military Academy operated with the support of the Soviet Union. The quality of education was guaranteed by regularly visiting Russian officers. Many of the leaders of both the Kuomintang and the CCP graduated from the academy—the chief commander of the People's Liberation Army, Lin Biao, graduated from Whampoa, as did Zhou Enlai, who later became premier of Communist China.

Fall
The First United Front was formed so the KMT and the CCP could join to strengthen China. The initial aim was to help defeat the warlord threat (through the Northern Expedition of 1926–28), but both parties actually had ulterior motives with this alliance. The CCP formed it mainly so it could spread communism within the KMT and its members, while Chiang's aim was to control the Communist Party from the inside. Having said that, he was also the main reason the relationship fell apart, due to his desire to control the Communist Party, ultimately leading to the disintegration of the First United Front. After purging the Communists and Soviet advisors from Whampoa and his Nationalist army during the 1926 "Canton Coup", Chiang went on to kill a large number of Communist forces in mid-1927, an event known as the Shanghai massacre. The massacre occurred about halfway through the Northern Expedition, ultimately ruining the First United Front and resulting in the Chinese Civil War. The Civil War was later postponed when the two sides formed the Second United Front to combat the Japanese in the Second Sino-Japanese War.
