Qin dynasty
Note: King Zhaoxiang of Qin (秦昭襄王) had already been ruling Qin for 51 years when Qin annihilated the Zhou dynasty; however the other six warring states were still independent regimes. Some Chinese historiographers thus used the next year (the 52nd year of King Zhaoxiang of Qin) as the official succession from the Zhou dynasty.
King Zhaoxiang of Qin
Due to this defeat, in 299 BC King Huai of Chu was forced to go to Wu Pass (武關) to negotiate terms with Qin, but along the way was abducted and taken to Xianyang instead. When he refused to cede the territory of the Wu Commandery (巫郡) and Qianzhong Commandery (黔中郡), he was detained as a hostage. King Zhaoxiang then proceeded to invade Chu the next year, capturing 16 cities and killing 50,000 Chu soldiers. King Huai of Chu did manage to escape in 297 BC, when Qin was distracted by a joint siege on Hangu Pass by Wei and Han, but he was recaptured when he was seeking asylum in Wei, after unsuccessfully doing so in the state of Zhao. He died a year later in captivity, and Qin finally returned his corpse back to Chu.
