Sun Yat-sen

Sun Yat-sen (; 12 November 1866 – 12 March 1925) was a Chinese physician, revolutionary and political philosopher who founded the Republic of China (ROC) and the Kuomintang (KMT). Sun is credited with leading the 1911 Revolution and overthrowing the Qing dynasty. He served as the first president of the Provisional Government of the Republic of China (1912) and as the inaugural premier of the Kuomintang.

Born to a poor peasant family in Guangdong, Sun was educated in Hawaii before graduating from the Hong Kong College of Medicine for Chinese in 1892. In 1894 he submitted a petition to reform the Qing government to Li Hongzhang, which was rejected. Sun subsequently went into exile and led anti-Qing movements overseas, founding the Revive China Society, the Tongmenghui, and the People's News.

Following the 1911 Revolution, Sun proclaimed the establishment of the Republic of China but relinquished the presidency to Beiyang Army leader Yuan Shikai in exchange for securing the Qing court's abdication. After the assassination of Song Jiaoren in 1913, widely attributed to Yuan, Sun led a failed Second Revolution against him, after which Sun fled to Japan. In 1917, Sun established a Constitutional Protection junta in Guangzhou, but before his planned Northern Expedition against the warlords, he was forced to resign due to infighting. Sun assumed the junta leadership in 1921, survived Chen Jiongming's revolt, and collaborated with Soviet Union and the Chinese Communist Party to form the First United Front. In late 1924, he traveled north beyond his base in Guangdong to call for a national assembly and the abolition of unequal treaties, continuing his struggle against the warlords Duan Qirui and Zhang Zuolin. He died in Beijing in 1925.

Sun is revered by both the Republic of China, which designates him "Father of the Nation," and the People's Republic of China, which honors him as the "Forerunner of the Revolution." Sun's flagship ideology, Three Principles of the People, sought to modernize China through nationalism, democracy, and the people's livelihood, within an ethnically harmonious conception of the Chinese nation.
