King Zhaoxiang of Qin
Reigning over 55 years, he was one of the longest-serving rulers during the Eastern Zhou Dynasty. Although making numerous policy mistakes during his later years, his aggressive territorial expansions were pivotal in consolidating the state of Qin as the dominant military powerhouse in the late Warring States period. It was the strategic dominance established during his reign that paved the way to Qin's eventual successful unification of China under his great-grandson, Ying Zheng.
King Zhaoxiang of Qin
In 273 BC, Wei and Zhao allied together to attack Han's Huayang (華陽). Qin offered military help to Han, defeating and killing 130,000 Wei soldiers, and drowning 20,000 Zhao soldiers in the Yellow River. In 269 BC, King Huiwen of Zhao backflipped on his previous promise to send hostages and concede land. In response, Qin attacked Zhao and laid siege to Yuyu (閼與). The siege was lifted after the Zhao general Zhao She (趙奢) ambushed and decisively defeated the invading Qin army. In 265 BC, Qin struck back at Zhao and captured three cities, and King Huiwen of Zhao resorted to sending his son to the state of Qi in exchange for Qi assistance, which forced the Qin army to withdraw.
