The Kuomintang (KMT) is a Chinese political party that ruled mainland China from 1927 to 1949 prior to its relocation to Taiwan as a result of the Chinese Civil War. The name of the party translates directly as "National People's Party of China" or "Chinese National Party" and was historically referred to as the Chinese Nationalists. The party was initially founded on 23 August 1912, by Sun Yat-sen but dissolved in November 1913. It reformed on October 10, 1919, again led by Sun Yat-sen, and became the ruling party in China. After Sun's death, the party was dominated from 1927 to 1975 by Chiang Kai-shek. After the KMT lost the civil war with the Chinese Communist Party in 1949, the party retreated to Taiwan and remains a major political party of the Republic of China based in Taiwan.

Founded in 1912 by Sun Yat-sen, the KMT helped topple the Qing dynasty and promoted modernization along Western lines. The party played a significant part in the first Chinese first National Assembly where it was the majority party. However the KMT failed to achieve complete control. The post of president was given to Yuan Shikai (1859–1916) as reward for his part in the revolution. Yuan Shikai abused his powers, overriding the constitution and creating strong tensions between himself and the other parties. In July 1913, the KMT staged a 'Second Revolution' to depose Yuan. This failed and the following crack down by Yuan led to the dissolution of the KMT and the exile of its leadership, mostly to Japan. Subsequently, Yuan Shikai had himself made Emperor of China.

In exile, Sun Yat-sen and other former KMT members founded several revolutionary parties under various names but with little success. These parties were united by Sun in 1919 under the title "Kuomintang of China". The new party returned to Guangzhou in China in 1920 where it set up a government but failed to achieve control of all of China. After the death of Yuan Shikai in 1916, China fractured into many regions controlled by warlords. To strengthen the party's position, it accepted aid and support from the Soviet Union and its Comintern. The fledgling Chinese Communist Party was encouraged to join the KMT and thus formed the First United Front. The KMT gradually increased its sphere of influence from its Guangzhou base. Sun Yat-sen died in 1925 and Chiang Kai-shek (1887–1975) became the KMT strong man. In 1926 Chiang led a military operation known as the Northern Expedition against the warlords that controlled much of the country. In 1927, Chiang instigated the April 12 Incident in Shanghai in which the Chinese Communist Party and Communist elements of the KMT were purged.The event is also known as the Shanghai Massacre of 1927. See Tien-wei Wu, "A Review of the Wuhan Debacle: the Kuomintang-Communist Split of 1927". Journal of Asian Studies 1969 29(1): 125–143 The Northern Expedition proved successful and the KMT party came to power throughout China (except Manchuria) in 1927 under the leadership of Chiang. The capital of China was moved to Nanjing in order to be closer to the party's strong base in southern China.

The party was always concerned with strengthening Chinese identity at the same time it was discarding old traditions in the name of modernity. In 1929, the KMT government suppressed the textbook Modern Chinese History, widely used in secondary education. The Nationalists were concerned that, by not admitting the existence of the earliest emperors in ancient Chinese history, the book would weaken the foundation of the state. The case of the Modern Chinese History textbook reflects the symptoms of the period: banning the textbook strengthened the Nationalists' ideological control but also revealed their fear of the New Culture Movement and its more liberal ideological implications. The KMT tried to destroy the Communist party of Mao Zedong, but was unable to stop the invasion by Japan, which controlled most of the coastline and major cities, 1937–1945. Chiang Kai-shek secured massive military and economic aid from the United States, and in 1945 became one of the five permanent members of the UN Security Council, with a veto. The KMT governed most of China until it was defeated in the civil war by the Communists in 1949.

The leadership, the remaining army, and hundreds of thousands of businessmen and other supporters, two million in all, fled to Taiwan. They continued to operate there as the "Republic of China" and dreamed of invading and reconquering what they called "mainland China". The United States, however, set up a naval cordon after 1950 that has since prevented an invasion in either direction. The KMT kept the island under martial law for 38 years under rule by Chiang Kai-shek and his son Chiang Ching-kuo (1910–1988). As the original leadership died off, it made a peaceful transition to democracy, with full election of parliament in the early 1990s and first direct presidential election in 1996. After a defeat by the Democratic Progressive Party in 2000, the KMT returned to power in the elections of 2008 and 2012.

Early years

The Kuomintang traces its roots to the Revive China Society, which was founded in 1895 and merged with several other anti-monarchist societies as the Revolutionary Alliance in 1905. After the overthrow of the Qing dynasty in the 1911 Xinhai Revolution and the founding of the Republic of China, the Kuomintang was formally established on 25 August 1912 at the Huguang Guild Hall in Beijing where the Revolutionary Alliance and several smaller revolutionary groups joined to contest the first National Assembly elections.Strand 2002 59–60 Sun Yat-sen, who had just stepped down as provisional president of the Republic of China, was chosen as its overall leader under the title of premier (), and Huang Xing was chosen as Sun's deputy. However, the most influential member of the party was the third ranking Song Jiaoren, who mobilized mass support from gentry and merchants for the KMT on a platform of promoting constitutional parliamentary democracy. Though the party had an overwhelming majority in the first National Assembly, President Yuan Shikai started ignoring the parliamentary body in making presidential decisions, counter to the Constitution, and assassinated its parliamentary leader Song Jiaoren in Shanghai in 1913. Members of the KMT led by Sun Yat-sen staged the Second Revolution in July 1913, a poorly planned and ill-supported armed rising to overthrow Yuan, and failed.

Yuan dissolved the KMT in November (whose members had largely fled into exile in Japan) and dismissed the parliament early in 1914. Yuan Shikai proclaimed himself emperor in December 1915. While exiled in Japan in 1914, Sun established the Chinese Revolutionary Party, but many of his old revolutionary comrades, including Huang Xing, Wang Jingwei, Hu Hanmin and Chen Jiongming, refused to join him or support his efforts in inciting armed uprising against Yuan Shikai. In order to join the Chinese Revolutionary Party, members must take an oath of personal loyalty to Sun, which many old revolutionaries regarded as undemocratic and contrary to the spirit of the revolution. Thus, many old revolutionaries did not join Sun's new organization, and he was largely sidelined within the Republican movement during this period. Sun returned to China in 1917 to establish a rival government in Guangzhou, but was soon forced out of office and exiled to Shanghai. There, with renewed support, he resurrected the KMT on 10 October 1919, but under the name of the Chinese Kuomintang, as the old party had simply been called the Kuomintang. In 1920, Sun and the KMT were restored in Guangdong. In 1923, the KMT and its government accepted aid from the Soviet Union after being denied recognition by the western powers. Soviet advisers – the most prominent of whom was Mikhail Borodin, an agent of the Comintern – began to arrive in China in 1923 to aid in the reorganization and consolidation of the KMT along the lines of the Communist Party of the Soviet Union, establishing a Leninist party structure that lasted into the 1990s. The Chinese Communist Party (CCP) was under Comintern instructions to cooperate with the KMT, and its members were encouraged to join while maintaining their separate party identities, forming the First United Front between the two parties.

Soviet advisers also helped the Nationalists set up a political institute to train propagandists in mass mobilization techniques, and in 1923 Chiang Kai-shek, one of Sun's lieutenants from the Tongmenghui days, was sent to Moscow for several months' military and political study. At the first party congress in 1924, which included non-KMT delegates such as members of the CCP, they adopted Sun's political theory, which included the Three Principles of the People – nationalism, democracy, and people's livelihood.

War with communists

Following the death of Sun Yat-sen, General Chiang Kai-shek emerged as the KMT leader and launched the Northern Expedition in 1926 to defeat the northern warlords and unite China under the party. He halted briefly in Shanghai in 1927 to purge the Communists who had been allied with the KMT, which sparked the Chinese Civil War. When Kuomintang forces took Beijing, as the city was the de jure internationally recognized capital, though previously controlled by the feuding warlords, this event allowed the Kuomintang to receive widespread diplomatic recognition in the same year. The capital was moved from Beijing to Nanjing, the original capital of the Ming dynasty, and thus a symbolic purge of the final Qing elements. This period of KMT rule in China between 1927 and 1937 became known as the Nanjing decade.

In sum, the KMT began as a heterogeneous group advocating American-inspired federalism and provincial independence. However, after its reorganization along Soviet lines, the party aimed to establish a centralized one-party state with one ideology – Three Principles of the People. This was even more evident following Sun's elevation into a cult figure after his death. The control by one single party began the period of "", whereby the party was to control the government while instructing the people on how to participate in a democratic system. After several military campaigns and with the help of German military advisors (German planned fifth "extermination campaign"), the Communists were forced to withdraw from their bases in southern and central China into the mountains in a massive military retreat known famously as the Long March, an undertaking which would eventually increase their reputation among the peasants. Out of the 86,000 Communist soldiers that broke out of the pocket, only 20,000 would make the 10,000 km march to Shaanxi province. The Kuomintang continued to attack the Communists. This was in line with Chiang's policy of solving internal conflicts (warlords and communists) before fighting external invasions (Japan). However, Zhang Xueliang, who believed that the Japanese invasion constituted the greater prevailing threat, took Chiang hostage during the Xi'an Incident in 1937 and forced Chiang to agree to an alliance with the Communists in the total war against the Japanese. The Second Sino-Japanese War had officially started, and would last until the Japanese surrender in 1945. However, in many situations the alliance was in name only; after a brief period of cooperation, the armies began to fight the Japanese separately, rather than as coordinated allies. Conflicts between KMT and communists were still common during the war, and documented claims of Communist attacks upon the KMT forces, and vice versa, abound.
