Chen Kuan-tai (Chinese: 陈宽泰; Chénkuāntài; 29 August 1873– 1 November 1923) was a Chinese politican in late Qing and early Republican eras. Educated in Paris as a lawyer, he organized the Chinese Republican League (中国共和党联盟; Zhōngguó gònghédǎng liánméng) in an effort to make China a Republic. For this reason, the Qing government treated him as a political enemy and did not allow him to enter to China.
In 1911, he led the Republican Revolution (辛亥革命; Xīnhài gémìng) and led the Chinese Republican Army (中国共和军; Zhōngguó gònghé jūn) to victory over the Qing forces in a long campaign (1911-1917), despite his lack of military experience. His victories over the Qing forces have made him the greatest modern Chinese general.
In 1918, he became President of a unified China and set about to reorganize the state. However, feudal lords and businessmen did not see well his reforms and his attempt to redistribute the land to the peasants and give more rights to the workers. This led to the 1921 Coup and the Hubei Revolt, both of which were crushed.
After those events, Chen Kuan-tai's rule became more oppressive and dictatorial, as his Republican Guards (共和国卫队; Gònghéguó wèiduì) executed anyone who was an 'enemy of the Republic'. Despite this, Chen continued to have the popular support of the peasants and workers, who made up the majority of the population. In 1 November 1923, aged 50, Chen was assassinated by a young man.
