The Seven Heroes of the Warring States Period Struggle for Hegemony

Summary of the Seven Heroes' Struggle for Hegemony in the Warring States Period (475 BC - 221 BC) The Warring States Period was a period of fragmentation where princes competed for supremacy. Qi, Chu, Yan, Han, Zhao, Wei, and Qin competed for hegemony, and were eventually unified by Qin. Overview of the Seven Heroes: Qi was a powerful country in the east and flourished during the reigns of King Wei and King Xuan, but later declined due to isolation; Chu had the largest territory and was strong but was defeated by political corruption; Yanbei was weak, but King Zhao Leyi conquered Qi and was temporarily prosperous; Han was the youngest and weakest, Famous for the manufacture of crossbows; Zhao Jing and Hufu's cavalry and archery forces greatly increased, but declined after the Battle of Changping; Wei was the overlord at the beginning (Wenhou's Reform), but declined due to being surrounded by enemies; Qin took advantage of Shang Yang's Reform to rise, and swept the six countries with its "distant diplomacy and close attack". Key context: various countries implemented reforms to strengthen themselves (Qin Shang Yang, Wei Li Kui, Chu and Wu Qi, etc.); Political strategists Zhang Yi and Su Qin promoted the alliance of vertical and horizontal lines; the battles of Guiling and Maling (Qi defeated Wei), and the Battle of Changping (Bai Qi pitted Zhao 400,000, establishing the basis for the unification of Qin) and other battles reshaped the pattern. From 230 BC to 221 BC, Yingzheng destroyed the six kingdoms. Historical influence: Qin established the first unified dynasty and established centralization of power; war accelerated national integration; the contention of a hundred schools of thought left an ideological legacy. The essence of the struggle for hegemony is institutional innovation and order reshaping. Qin ended five hundred years of division with its advanced system and opened the era of empire.
