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
In 301 BC, the four states of Qin, Han, Wei and Qi allied together to attack Chu, defeating the Chu army at Zhongqiu (重丘) and killing the Chu general Tang Mei (唐眜). In 300 BC, King Zhaoxiang sent his uncle Mi Rong to capture Xiangcheng (襄城), killing 30,000 enemy and the Chu general Jing Que (景缺) in the process.
