Li Yuanhong
With Yuan Shikai's death the Warlord Era began. Vice President Li Yuanhong succeeded Yuan as president and attempted to reassert the constitutional government, but was soon forced to resign by military strongmen. The presidency, though leading an internationally recognized government, was thereafter to be headed by a series of prominent warlords. This presidency ended in 1928 when the Northern Expedition, led by the Kuomintang (KMT), succeeded in conquering North China.
