A report on Republic of China (1912–1949) and Chiang Kai-shek

It was the dominant party in China during the Republican Era from 1928 to 1949, when most of the Chinese mainland was under its control.

From 1926 to 1928, the KMT under Chiang Kai-shek successfully led the Northern Expedition against regional warlords and unified the fragmented nation.

The Second Sino-Japanese War (1937–1945) was a military conflict that was primarily waged between the Republic of China and the Empire of Japan.

Later in the same year, Zhang decided to declare his allegiance to the Nationalist government in Nanjing under Chiang Kai-shek, and consequently, China was nominally reunified under one government.

The Chinese Civil War was fought between the Kuomintang (KMT)-led government of the Republic of China (ROC) and forces of the Chinese Communist Party (CCP), lasting intermittently after 1927.

In 1923, Sun sent Chiang Kai-shek, one of his lieutenants, for several months of military and political study in Moscow.

Nanjing served as the capital of Eastern Wu (229–280), one of the three major states in the Three Kingdoms period; the Eastern Jin and each of the Southern dynasties (Liu Song, Southern Qi, Liang and Chen), which successively ruled southern China from 317 to 589; the Southern Tang (937–75), one of the Ten Kingdoms; the Ming dynasty when, for the first time, all of China was ruled from the city (1368–1421); and the Republic of China under the nationalist Kuomintang (1927–37, 1946–49) prior to its flight to Taiwan by Chiang Kai-Shek during the Chinese Civil War.

The expedition was led by Generalissimo Chiang Kai-shek, and was divided into two phases.

Before his death in March 1925, Sun Yat-sen, the founder of the Republic of China and co-founder of the KMT, was supportive of Sino-Soviet co-operation, which had involved forming the First United Front with the Chinese Communist Party (CCP).

Sun Yat-sen (born Sun Te-ming; 12 November 1866 – 12 March 1925), also known as Sun Yat-sun, Sun Chung-shan, Sun Yi-hsien, Sun Wen, Sun Jih-hsin, Suen Yat-sen, Suen Yat-sun, Sun Yixian and Sun Rixin, was a Chinese statesman, physician, and political philosopher, who served as the first provisional president of the Republic of China and the first leader of the Kuomintang (Nationalist Party of China).

He did not live to see his party unify the country under his successor, Chiang Kai-shek, in the Northern Expedition.

The Republic of China, which had overthrown the Qing in 1911, took control of Taiwan on behalf of the Allies of World War II following the surrender of Japan in 1945.

After the end of World War II, the Chinese Civil War resumed between the Chinese Nationalists (Kuomintang), led by Generalissimo Chiang Kai-shek, and the Chinese Communist Party (CCP), led by CCP Chairman Mao Zedong.

The Chinese monarchy collapsed in 1912 with the Xinhai Revolution, when the Republic of China (ROC) replaced the Qing dynasty.

In the late 1920s, the Kuomintang under Chiang Kai-shek, the then Principal of the Republic of China Military Academy, was able to reunify the country under its own control with a series of deft military and political maneuverings, known collectively as the Northern Expedition.

In historiography, the Warlord Era began in 1916 upon the death of Yuan Shikai, the de facto dictator of China after the Xinhai Revolution overthrew the Qing dynasty and established the Republic of China in 1912.

The Warlord Era ended in 1928 when the Kuomintang under Chiang Kai-shek officially unified China through the Northern Expedition, marking the beginning of the Nanjing decade.

Japan, which aimed to dominate Asia and the Pacific, was at war with the Republic of China by 1937.

Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai, but after three months of fighting, Shanghai fell.
