A plan backed by foreign bankers was reported in place to declare the Duke Yansheng as Emperor of China as a Han emperor, if the revolutionary's republican plan failed. Republic of China After Western ideologies came to China during the May Fourth Movement, Li Dazhao and other communists established the Chinese Communist Party in 1921 with the support of the Comintern. Communist Party members are allowed to join the Kuomintang (KMT; Nationalist Party), which, under the leadership of Sun Yat-sen, was seeking an alliance to end the Warlord Era and unify China. As the new leader of the KMT, Chiang Kai-shek, launched the Northern Expedition to unify China in 1924. Conservatives within the KMT in Nanking grew hostile to the communists, while the leftists in Wuhan were in favour of the alliance with them.

By October 1949, the Communists occupied most of the Mainland China, and Mao Zedong of the CCP declared the People's Republic of China in Beijing. The Government of the Republic of China relocated to Taipei and has failed to retake the mainland since then. Taiwan and part of Fujian Province became known as the Free Area of the Republic of
