First United Front in the context of "Chinese Civil War"

The Kuomintang (KMT) is a major political party in the Republic of China (Taiwan). It was the sole ruling party of the country during its rule from 1927 to 1949 in Mainland China until its relocation to Taiwan, and in Taiwan ruled under martial law until 1987. The KMT is a centre-right to right-wing party and the largest in the Pan-Blue Coalition, one of the two main political groups in Taiwan. Its primary rival is the Democratic Progressive Party (DPP), the largest party in the Pan-Green Coalition. As of 2025, the KMT is the largest single party in the Legislative Yuan and is chaired by Cheng Li-wun.

The party was founded by Sun Yat-sen in 1894 in Honolulu, Hawaii, as the Revive China Society. He reformed the party in 1919 in the Shanghai French Concession under its current name. From 1926 to 1928, the KMT under Chiang Kai-shek successfully unified China in the Northern Expedition against regional warlords, leading to the fall of the Beiyang government. After initially allying with the Chinese Communist Party (CCP) in the First United Front, the party under Chiang purged communist members. It was the sole ruling party of China from 1928 to 1949 but gradually lost control while fighting the Empire of Japan in the Second Sino-Japanese War and the CCP in the Chinese Civil War. In December 1949, the Kuomintang retreated to Taiwan following its defeat by the communists.

The Northern Expedition was a military campaign launched by the National Revolutionary Army (NRA) of the Kuomintang (KMT) against the Beiyang government and other regional warlords in 1926. The purpose of the campaign was to reunify China, which had become fragmented in the aftermath of the 1911 Revolution. The expedition was led by Generalissimo Chiang Kai-shek, and was divided into two phases. The first phase ended in a 1927 political split between two factions of the KMT: the right-leaning Nanjing faction, led by Chiang, and the left-leaning faction in Wuhan, led by Wang Jingwei. The split was partially motivated by Chiang's Shanghai Massacre of Communists within the KMT, which marked the end of the First United Front. In an effort to mend this schism, Chiang Kai-shek stepped down as the commander of the NRA in August 1927, and went into exile in Japan.

The second phase of the Expedition began in January 1928, when Chiang resumed command. By April 1928, the nationalist forces had advanced to the Yellow River. With the assistance of allied warlords, including Yan Xishan and Feng Yuxiang, the nationalist forces secured a series of decisive victories against the Beiyang Army. As they approached Beijing, Zhang Zuolin, leader of the Manchuria-based Fengtian clique, was forced to flee and was later assassinated shortly thereafter by the Japanese. His son, Zhang Xueliang, took over as the leader of the Fengtian clique, and in December 1928, announced that Manchuria would accept the authority of the nationalist government in Nanjing. With the final piece of China under KMT control, the Northern Expedition concluded successfully and China was reunified, heralding the start of the Nanjing decade.

Chiang Kai-shek (31 October 1887 – 5 April 1975) was a Chinese politician, revolutionary, and military commander who led the Republic of China (ROC) from 1928 until his death in 1975. His government was based in mainland China until it was defeated in the Chinese Civil War by Mao Zedong's Chinese Communist Party (CCP) in 1949, after which he continued to lead the ROC government on the island of Taiwan. Chiang served as leader of the Nationalist Kuomintang (KMT) party and the commander-in-chief of the National Revolutionary Army (NRA), which was reorganized into the Republic of China Armed Forces in 1947, from 1926 until his death.

Born in Zhejiang, Chiang received a military education in China and Japan and joined Sun Yat-sen's Tongmenghui organization in 1908. After the 1911 Revolution, he was a founding member of the KMT and head of the Whampoa Military Academy from 1924. After Sun's death in 1925, Chiang became leader of the party and commander-in-chief of the NRA, and from 1926 to 1928 led the Northern Expedition, which nominally reunified China under a Nationalist government based in Nanjing. The KMT–CCP alliance broke down in 1927 following the KMT's Shanghai Massacre, starting the Chinese Civil War. Chiang sought to modernise and unify the ROC during the Nanjing decade, although hostilities with the CCP continued. After Japan's invasion of Manchuria in 1931, his government tried to avoid a war while pursuing economic and social reconstruction. In 1936, Chiang was kidnapped by his generals in the Xi'an Incident and forced to form an anti-Japanese Second United Front with the CCP, and between 1937 and 1945 led China in the Second Sino-Japanese War, mostly from the wartime capital of Chongqing. As the leader of a major Allied power, he attended the 1943 Cairo Conference to discuss the terms for Japan's surrender in 1945, including the return of Taiwan, where he suppressed the February 28 uprising in 1947.

The Chinese Communist Revolution was a social and political revolution in mainland China that began in 1927 and culminated with the proclamation of the People's Republic of China (PRC) in 1949. The revolution was led by the Chinese Communist Party (CCP), which afterwards became the ruling party of China. The political revolution resulted in major social changes within China and has been looked at as a model by revolutionary communist movements in other countries.

During the preceding century, termed the century of humiliation, the decline of the Qing dynasty and the rise of foreign imperialism caused escalating social, economic, and political problems in China. The Qing collapsed in 1912 and were replaced with the Republic of China, which had itself fallen into warring factions by 1917. A small group of urban intellectuals, inspired by the October Revolution and European socialist ideas, founded the CCP in 1921. They created an alliance known as the First United Front with the much larger Kuomintang (KMT), having the shared goal of overthrowing the warlords governing China. During this period the CCP rapidly expanded its membership, organized a militant labor movement in several of China's major cities, and established rudimentary peasant associations in rural areas. Nonetheless, and despite the First United Front's military successes, KMT leader Chiang Kai-shek ended the alliance in 1927 by initiating the Shanghai massacre.

Chiang Ching-kuo (/ˈtʃæŋtʃɪŋˈkwoʊ/, 27 April 1910 – 13 January 1988) was a Chinese politician and statesman. He was the eldest and only biological son of President Chiang Kai-shek, he held numerous posts in the government of the Republic of China and ended martial law in 1987. He served as the third premier of the Republic of China between 1972 and 1978 and was the third president of the Republic of China from 1978 until his death in 1988.

Born in Fenghua, Ching-kuo was sent as a teenager to study in the Soviet Union during the First United Front in 1925, when his father's Nationalist Party and the Chinese Communist Party were in alliance. Before his education in the USSR, he attended school in Shanghai and Beijing, where he became interested in socialism and communism. He attended university in the USSR and spoke Russian fluently, but when the Chinese Nationalists violently broke with the Communists, Joseph Stalin sent him to work in a steel factory in the Ural Mountains. There, Chiang met and married Faina Vakhreva. With war between China and Japan imminent in 1937, Stalin sent the couple to China. During the war, Ching-kuo's father gradually came to trust him, and gave him more and more responsibilities, including administration.

"The Party commands the gun" (Chinese: 党指挥枪; pinyin: Dǎng zhǐhuī qiāng) is a policy and slogan of the Chinese Communist Party (CCP) to emphasize its absolute control of the People's Liberation Army (PLA). It was first used by CCP leader Mao Zedong in his 1938 article Problems of War and Strategy. The original text reads "Our principle is that the Party commands the gun, and we will never allow the gun to command the Party."

Mao believed that the Chinese Communist Party could not achieve revolution through solely peaceful means. He also mentioned that during the First United Front with the Kuomintang, the CCP "ignored the struggle for the army and focused one-sidedly on the mass movement", and was eventually suppressed after the split with the Kuomintang. Mao then used the example of the Kuomintang's war history of controlling the army to illustrate that the CCP should "derive political power from the barrel of a gun" and put forward the principle of "the Party commands the gun, but never allows the gun to command the Party".
