Constitutional Protection Movement
After Yuan's death, Li Yuanhong became President and the National Assembly convened again. The party split into two factions: the Constitution Research Clique led by Liang and the Constitution Discussions Clique led by Tang Hualong. Liang supported Premier Duan Qirui's plan to push China into World War I on the Allied side against the wishes of President Li in hopes of regaining lost territories. When the Assembly was dissolved again during the Manchu Restoration (of which Kang Youwei took part) some ex-Progressives joined Sun Yat-sen's Constitutional Protection Movement. Liang and his followers refused to join because they felt a rival government was harmful to China's national integrity and that the movement was itself unconstitutional because it was a military government.
