He died in Peking ( Beijing) of gallbladder cancer on 12 March 1925.

He did not live to see his party unify the country under his successor, Chiang Kai-shek, in the Northern Expedition. In 1923, he invited representatives of the Communist International to Canton ( Guangzhou) to re-organize his party and formed a brittle alliance with the Chinese Communist Party.

He soon went to exile in Japan for safety but returned to found a revolutionary government in the South as a challenge to the warlords who controlled much of the nation. After the success of the revolution in 1911, he quickly resigned as president of the newly founded Republic of China and relinquished it to Yuan Shikai. Sun is considered to be one of the greatest leaders of modern China, but his political life was one of constant struggle and frequent exile. Sun is unique among 20th-century Chinese leaders for being widely revered in both Mainland China and Taiwan. He is called the ' Father of the Nation' in the Republic of China, and the 'Forerunner of the Revolution' in the People's Republic of China for his instrumental role in the overthrow of the Qing dynasty during the Xinhai Revolution. Sun Yat-sen ( / ˈ s ʌ n ˌ j æ t ˈ s ɛ n/ also known by several other names 12 November 1866 – 12 March 1925) 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).
