First predominantly Han Chinese state in Taiwanese history, founded by the Ming-loyalist warlord Koxinga (Zheng Chenggong) after he expelled the Dutch VOC from Fort Zeelandia; ruled by his descendants (the House of Koxinga) as a Ming-restorationist base against the Qing.
Surrendered to Qing admiral Shi Lang following the 1683 Battle of Penghu, ending the Zheng regime and bringing Taiwan under Qing administration for the first time.
