What island provided refuge for the Chinese nationalists after the Chinese revolution?

The Nationalist Forces in the Chinese Civil War, led by Jiang Jeshi (also called Chiang Kai-Shek), withdrew to the island of TAIWAN (also called FORMOSA) at the end of the Chinese Civil War in 1949. At that point, the Communists chose not pursue them, leading to two functionally independent Han Chinese-majority states: the People's Republic of China (Mainland China) and the Republic of China (Taiwan).
