Hu Hanmin
In 1931, the near civil war caused by the arrest of Hu Hanmin and the invasion of Manchuria forced Chiang Kai-shek to resign. For one month, he was President of the Executive Yuan (Premier). He found the government was paralyzed by the absence of the party's Big Three: Hu, Chiang, and Wang Jingwei. High level negotiations brought the latter two back into politics with Wang becoming premier.
