Kingdom of Tungning
After its defeat in the Chinese Civil War in 1949, the Republic of China (ROC), led by the Kuomintang, went to Taiwan. They left mainland China to the Communist Party who started the People's Republic of China (PRC). For many years, the ROC planned to take control of the mainland. It kept island bases close to the mainland (for example, Quemoy). This was the same as Koxinga and his sons had done. The ROC has now become a democracy and no longer wants to take over the mainland. The political and territorial arrangement has not changed. In this way, it is the same as between the Qing/Koxinga situation and the current PRC/ROC situation.
