Concept
The Beiyang government (), officially the Republic of China (), sometimes spelled Peiyang Government, or just China, was the government of the Republic of China which sat in its capital Beijing between 1912 and 1928. It was internationally recognized as the legitimate Chinese government during that time. The name derives from the Beiyang Army, which dominated its politics with the rise of Yuan Shikai, who was a general of the Qing dynasty. After his death, the army split into various warlord factions competing for power, in a period called the Warlord Era. Although the government and the state were nominally under civilian control under a constitution, the Beiyang generals were effectively in charge of it. Nevertheless, the government enjoyed legitimacy abroad along with diplomatic recognition, had access to tax and customs revenue, and could apply for foreign financial loans. Its legitimacy was seriously challenged in 1917, by Sun Yat-sen's Canton-based Kuomintang (KMT) government movement. His successor Chiang Kai-shek defeated the Beiyang warlords during the Northern Expedition between 1926 and 1928, and overthrew the factions and the government, effectively unifying the country in 1928. The Kuomintang proceeded to install its nationalist government in Nanking; China's political order became a one-party state, and the Kuomintang government subsequently received international recognition as the legitimate government of China. Under the Provisional Constitution of the Republic of China, as drawn up by the provisional senate in February 1912, the National Assembly (parliament) elected the president and vice president for five-year terms, and appointed a premier to choose and lead the cabinet. The relevant ministers had to countersign executive decrees for them to be binding. The most important ministries were army, finance, communications, and interior. The navy ministry's importance declined significantly after most of its ships defected to the South's Constitutional Protection Movement in 1917.
