明鄭時期
Officially, the PRC traces Chinese sovereignty over Taiwan, allegedly historically known by the Chinese as "Liuqiu" (which is closely related to the name of the modern Japanese Ryukyu Islands), back to roughly around the 3rd century CE (specifically the year 230 CE). However, most Western sources officially trace Chinese sovereignty over Taiwan back to either 1661–1662 CE (the year(s) when Koxinga established the Kingdom of Tungning in southwestern Taiwan) or 1683 CE (the year when the Qing dynasty (of China) absorbed the Kingdom of Tungning into its territory and subsequently lay claim to the entire island).
