Provisional Constitution of the Republic of China

After victory in the Xinhai Revolution, the Nanjing Provisional Government of the Republic of China, led by Sun Yat-sen, framed the Provisional Constitution of the Republic of China (, 1912), which was an outline of basic regulations with the qualities of a formal constitution.
On 11 March 1912, the Provisional Constitution replaced the previous organizational outline of the government, and came into effect as the supreme law. It was later replaced by a constitutional compact instituted by Yuan Shikai. However, it was restored once again on 29 June 1916, by President Li Yuanhong.
The Constitutional Protection Movement launched by the Military Government of the Republic of China in Guangzhou on 10 September 1917, was intended to "protect" this provisional constitution. However, as the Warlord Era divided the country into warring factions, the provisional constitution was gradually superseded by the constitutions issued by each rival government. In the Beiyang Government, the provisional constitution was replaced by Cao Kun's constitution on 10 October 1923. In the Nanjing Government, the provisional constitution was not replaced until 1 June 1931, when the Provisional Constitution of the Political Tutelage Period was announced, although the old constitution was already rarely discussed after the establishment of the Nationalist Government on 1 July 1925. From 1928 onwards, the Nationalists were operating under an Organic Law that had an ambiguous relationship with the 1931 Provisional Constitution as it was not completely superseded.
The Constitution of the Republic of China superseded it in 1946, ending the Period of Tutelage.
