After the North Expedition, the Kuomintang acquired control of a unified China nominally. The party began to draft a constitution to transit the government from tutelage period to constitutional period, according the political philosophy of Sun Yat-sen.
During the Second Sino-Japanese War, China established a close partnership with the United States and was given military and financial supports. George Marshall was appointed ambassador to Chongqing, the wartime capital, as to broker a negotiation between the Kuomintang and Communists after the war. Two parties agreed to rebuild the country with democratization and military nationalization.
Simultaneously, the Government of the Republic of China continued to draft the Constitution, however it was boycotted by the Communists and the full-scale Civil War was resumed.
The indirect elections were held during the Civil War, elected by the members of the National Assembly. Generalissimo Chiang Kai-shek won a landslide victory against the same party candidate Ju Zheng in the presidential election, while Sun Fo, his preferred Vice-Presidential candidate, was defeated by General Li Zongren in the vice-presidential elections.
