Definition The Battle of Changping was a decisive military engagement fought in 260 BCE during the Warring States period of ancient China, between the states of Qin and Zhao. It resulted in a major victory for the Qin state and is considered one of the largest and most significant battles of the era, marking a turning point in Qin's ascendancy prior to the unification of China.
Overview The Battle of Changping took place near the Changping region, located in present-day Gaoping, Shanxi Province, China. It occurred during a prolonged conflict over the Shangdang Commandery, a strategically important area that had previously belonged to the state of Han. After Han ceded the territory to Zhao, the Qin state, under General Wang He (later replaced by Bai Qi), launched a campaign to seize it, leading to a prolonged standoff and eventual large-scale confrontation.
For several months, the opposing armies faced each other with limited engagement. Zhao initially employed General Lian Po, who adopted a defensive strategy. However, under pressure from the Zhao court and possibly due to Qin's use of disinformation, Lian Po was replaced by the less experienced Zhao Kuo, who favored an offensive approach. Seizing the opportunity, Qin's commander Bai Qi feigned retreat, lured Zhao Kuo into an ambush, and encircled the Zhao army. The Zhao forces were cut off from supplies and reinforcements, and after a prolonged siege, they were decisively defeated.
It is traditionally recorded that around 400,000 Zhao soldiers were captured and subsequently executed by the Qin forces, although the exact number remains debated by modern historians. This massive loss severely weakened the state of Zhao and eliminated its ability to resist Qin's expansion, paving the way for Qin's eventual conquest of the other Warring States.
Etymology/Origin The term "Changping" refers to the geographical location where the battle occurred. Its name derives from classical Chinese, where "Chang" (长) means "long" and "ping" (平) means "peace" or "flatland." The site was part of a mountainous yet strategically passable region, making it a critical military corridor. The battle is commonly referred to as the "Battle of Changping" in English historiography, reflecting direct translation from Chinese sources such as the Records of the Grand Historian (Shiji) by Sima Qian.
