The establishment of people's Republic of China was the event that led to the reestablishment of the Republic of China.
The Republic of China was a state in East Asia from 1912 to 1949. It largely occupied the present-day territories of China, Taiwan, and, for some of its history, Mongolia. As an era of Chinese history, it was preceded by the last imperial dynasty of China, the Qing dynasty, and ended with the Chinese Civil War.
