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 manga and anime Kingdom, he was described as a "War God", which he led Qin through bloody battles alongside his 6 most elite generals, including Bai Qi, Wang He, Wang Yi, Liao, Si Ma Cuo and Hu Shang.
