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.
Qin Zongquan
Qin Zongquan (; died April 1, 889) was a warlord of the Chinese dynasty Tang Dynasty and later a claimant to the imperial throne, in competition with Emperor Xizong of Tang and, later, Emperor Xizong's brother Emperor Zhaozong, with his capital at Cai Prefecture (蔡州, in modern Zhumadian, Henan). At Qin's prime, he controlled most of modern Henan and parts of modern Hubei, Anhui, and Jiangsu, but he was eventually repeatedly defeated by the Tang general Zhu Quanzhong. His subordinates turned against him and delivered him to the Tang capital Chang'an, where he was executed.
