'King Huai of Chu' was a descendant of the fallen Chu royal family, but he lived a quiet life as a poor shepherd. That is, until Xiang Yu's uncle, a rebel leader, found him and made him a puppet king just to win the hearts and support of the people. However, when Xiang Yu's uncle died in battle, everything changed. As panic spread among the rebel forces, King Huai seized the opportunity to take over the scattered armies and become the actual Supreme Commander. When the King held a war council to plan the invasion of Qin, his biggest concern was Xiang Yu, who was unbelievably strong but notoriously cruel and uncontrollable. To keep Xiang Yu in check, the King deliberately appointed him as a subordinate in the northern army, sending him on a difficult route to fight the brutal main Qin army. Meanwhile, the King entrusted the easygoing and merciful Liu Bang with the safest and most direct route toward the Qin capital, hoping Liu Bang would win over the people and secure a peaceful surrender. The King then announced an incredible promise to the world: 'Whoever enters the Qin heartland (Guanzhong) first shall become its king!'
During this campaign, Xiang Yu proved his absolute military genius at the Battle of Julu in the north, where he shattered the main Qin army. He earned the terrifying respect of all other rebel generals, who crawled on their knees to meet him, cementing his position as the supreme military commander. Meanwhile, Liu Bang, though lacking martial skills, gathered a brilliant team of advisors through his easygoing charm and successfully advanced west. Liu Bang arrived in Guanzhong first and won the people over with kindness. But Xiang Yu, furious after completing his northern campaign, soon arrived with a much larger army and forced Liu Bang out with brute strength. This broken promise sparked the deadly, ultimate showdown between the two heroes.
In 206 BC, the Qin dynasty collapsed. Xiang Yu, with his overwhelming military power, divided the empire into Eighteen Kingdoms and declared himself the 'Hegemon-King of Western Chu'. He gave Liu Bang the remote and harsh region of Hanzhong, making him the King of Han. Liu Bang, secretly building his strength and employing the military genius Han Xin, eventually broke out of Hanzhong to challenge Xiang Yu's supremacy.
The war was characterized by Xiang Yu's tactical brilliance and Liu Bang's strategic resilience. Xiang Yu won many direct battles, such as the Battle of Pengcheng (205 BC), where he decisively crushed a massive coalition army led by Liu Bang. However, Liu Bang's superior political skills allowed him to survive, form alliances, and cut off Xiang Yu's supply lines.
While Liu Bang tied down Xiang Yu's main forces, his general Han Xin launched a highly successful northern campaign, conquering rival states and completely isolating Xiang Yu. In 202 BC, Liu Bang, Han Xin, and other allied forces surrounded Xiang Yu at the Battle of Gaixia. Hearing his enemies singing the songs of his homeland (a psychological tactic known as 'Chu songs on all sides'), Xiang Yu's army broke down. Xiang Yu committed suicide, and Liu Bang became the sole ruler of China, establishing the Han dynasty.
