段祺瑞
After Yuan Shikai's death, Li Yuanhong became the President and Duan Qirui became the Premier. The Provisional Constitution was reinstated and the parliament convened. However, Li Yuanhong and Duan Qirui had many conflicts, the most glaring of which was over China's entry into World War I. Since the outbreak of the war, China had remained neutral until the United States urged all neutral countries to join the Allies, as a condemnation of Germany's use of unrestricted submarine warfare. Premier Duan Qirui was particularly interested in joining the Allies as an opportunity to secure loans from Japan to build up his Anhui clique army. The two factions in the parliament engaged in ugly debates regarding the entry of China and, in May 1917, Li Yuanhong dismissed Duan Qirui from his government.
