When did the CCP come to power? What part of China remained outside its control?

The Chinese Communist Party (CCP) came to power led by Mao Zedong after World War II. The island of Taiwan remained outside the control of the CCP, since the Kuomintang army led by Chiang Kai-shek was consolidated there. He also, like Mao Zedong, claimed power throughout China and began to carry out his reforms on the island. This is how the “two China” was formed.
