Names and titles

Xiang Yu's family name was Xiang (項 Xiàng) while his given name was Ji (籍 Jí|w=Chi|j=Zik6|labels=no) and his courtesy name was Yu (羽 Yǔ|w=Yü|j=Jyu5|labels=no). He is best known as Xiang Yu.

Xiang Yu is popularly known as "Xi Chu Ba Wang" (西楚霸王 Xī Chǔ Bà Wáng|w=Hsi Ch'u Pa Wang|j=Sai1 Co2 Baa3 Wong4|labels=no), which has been translated as "Overlord of Western Chu", "Hegemon-King of Western Chu", "Conqueror of Western Chu", "King of Kings of Western Chu", and other renditions. This title is sometimes simplified to "Ba Wang" (霸王 Bà Wáng|w=Pa Wang|j=Baa3 Wong4|labels=no), without the link to "Western Chu". Since Xiang Yu's death, the term Ba Wang has come to be used specifically to refer to him. Xiang Yu's subjects would sometimes have addressed him as "Xiang Wang" (項王 Xiàng Wáng), which literally means "King Xiang".

Family background

There are two accounts of Xiang Yu's family background. The first claimed that Xiang Yu was from the house of Mi (羋), the royal family of the Chu state in the Zhou dynasty. His ancestors were granted the land of Xiang (項) by the king of Chu and had since adopted "Xiang" as their family name. The other account claimed that Xiang Yu was a descendant of a noble clan from the Lu state and his family had served in the Chu military for generations. Xiang Yu's grandfather was a well known general who led the Chu army in resisting the Qin invaders led by Wang Jian, and was killed in action when Qin conquered Chu in 223 BC.

Xiang Yu was born in 232 BC in the late Warring States period when the Qin state started unifying the other six major states. According to the descendants of the Xiang family in Suqian, Xiang Yu's father was Xiang Chao (項超), Xiang Yan's eldest son. Xiang Yu was raised by his elder uncle Xiang Liang because his father died early. In 221 BC, when Xiang Yu was about 11 years old, the Qin state unified China and established the Qin dynasty.

Xiang Yu had a double pupil in one of his eyes just like the mythical Emperor Shun and Duke Wen of Jin. He was thus seen as an extraordinary person because his unique double pupil was a mark of a king or sage in Chinese tradition. Xiang Yu was slightly taller than eight chi (approximately 1.85 metres, about 6' 1") and possessed unusual physical strength as he could lift a ding (an ancient Chinese vessel resembling a giant cauldron on tripods).

Early life

In his younger days, Xiang Yu was instructed in scholarly arts and swordsmanship but he did not manage to master what he was taught, and his uncle Xiang Liang was not very satisfied with him. Xiang Yu said, "Books are only useful in helping me remember my name. Mastering swordsmanship allows me to face only one opponent, so it's not worth learning. I want to learn how to defeat thousands of enemies." Hence, his uncle tried to educate him in military strategy and the art of war instead, but Xiang Yu stopped learning after he had grasped the main ideas; Xiang Liang was disappointed with his nephew, who showed no sign of motivation or apparent talent apart from his great strength, so he gave up and let Xiang Yu decide his own future.

When Xiang Yu grew older, Xiang Liang killed someone so they fled to Wu to evade the authorities. At the time, Qin Shi Huang was on an inspection tour in that area and Xiang Yu and his uncle watched the emperor's procession pass by. Xiang Yu said, "I can replace him." Xiang Liang was shocked and immediately covered his nephew's mouth with his hand. Afterwards, Xiang Liang began to see his nephew in a different light.

Revolution against the Qin dynasty

In 209 BC, during the reign of Qin Er Shi, peasant rebellions erupted throughout China to overthrow the Qin dynasty, plunging China into a state of anarchy. , the Administrator of Kuaiji, wanted to start a rebellion as well, so he invited Xiang Liang to meet him and discuss their plans. However, the Xiangs lured Yin Tong into a trap and killed him instead, with Xiang Yu personally striking down hundreds of Yin's men. Xiang Liang initiated the rebellion himself and rallied about 8,000 men to support him. Xiang Liang proclaimed himself Administrator of Kuaiji while appointing Xiang Yu as a general. Xiang Liang's revolution force grew in size until it was between 60,000 and 70,000. In 208 BC, Xiang Liang installed Mi Xin as King Huai II of Chu to rally support from those eager to help him overthrow the Qin Dynasty and restore the former Chu state. Xiang Yu distinguished himself as a competent marshal and mighty warrior on the battlefield while participating in the battles against Qin forces.

Later that year, Xiang Liang was killed at the Battle of Dingtao against the Qin army led by Zhang Han and the military power of Chu fell into the hands of the king and some other generals. In the winter of 208 BC, another rebel force claiming to restore the Zhao state, led by Zhao Xie, was besieged in Handan by Zhang Han. Zhao Xie requested for reinforcements from Chu. King Huai II granted Xiang Yu the title of "Duke of Lu" (魯公), and appointed him as a second-in-command to Song Yi, who was ordered to lead an army to reinforce Zhao Xie. At the same time, the king placed Liu Bang in command of another army to attack Guanzhong, the heartland (capital territory) of Qin. The king promised that whoever managed to enter Guanzhong first will be granted the title "King of Guanzhong".

Battle of Julu

The Chu army led by Song Yi and Xiang Yu reached Anyang, some distance away from Julu (巨鹿; in present-day Xingtai, Hebei), where Zhao Xie's forces had retreated to. Song Yi ordered the troops to lay camp there for 46 days and he refused to accept Xiang Yu's suggestion to proceed further. Xiang Yu took Song Yi by surprise in a meeting and killed him on a charge of treason. Song Yi's other subordinates were afraid of Xiang Yu so they let him become the acting commander-in-chief. Xiang Yu sent a messenger to inform King Huai II and the king approved Xiang's command.

In 207 BC, Xiang Yu's army advanced towards Julu and he sent Ying Bu and Zhongli Mo to lead the 20,000 strong vanguard army to cross the river and attack the Qin forces led by Zhang Han, while he followed behind with the remaining majority of the troops. After crossing the river, Xiang Yu ordered his men to sink their boats and destroy all but three days worth of rations, in order to force his men to choose between prevailing against overwhelming odds within three days or die trapped before the walls of the city with no supplies or any hope of escape. Despite being heavily outnumbered, Chu forces scored a great victory after nine engagements, defeating the 300,000 strong Qin army. After the battle, other rebel forces, including those not from Chu, came to join Xiang Yu out of admiration for his martial valour. When Xiang Yu received them at the gate, the rebel chiefs were so fearful of him that they sank to their knees and did not even dare to look up at him.

Zhang Han sent his deputy Sima Xin to Xianyang to request for reinforcements and supplies from the Qin imperial court. However, the eunuch Zhao Gao deceived the emperor and the emperor dismissed Zhang Han's request. Zhao Gao even sent assassins to kill Sima Xin when the latter was returning to Zhang Han's camp, but Sima managed to escape alive. In dire straits, Zhang Han and his 200,000 troops eventually surrendered to Xiang Yu in the summer of 207 BC. Xiang Yu perceived the surrendered Qin troops as disloyal and a liability, and had them executed by burying them alive at Xin'an (新安; in present-day Yima, Henan). Zhang Han, along with Sima Xin and Dong Yi, were spared from death. Xiang Yu appointed Zhang Han as "King of Yong", while Sima Xin and Dong Yi were respectively conferred the titles of "King of Sai" and "King of Di".

Feast at Hong Gate

After his victory at the Battle of Julu, Xiang Yu prepared for an invasion on Guanzhong, the heartland of the Qin dynasty. In the winter of 207 BC, the last Qin ruler Ziying surrendered to Liu Bang in Xianyang (Qin's capital), bringing an end to the Qin Dynasty. When Xiang Yu arrived at Hangu Pass, the eastern gateway to Guanzhong, he saw that the pass was occupied by Liu Bang's troops, a sign that Guanzhong was already under Liu's control. Cao Wushang (曹無傷), a subordinate of Liu Bang, sent a messenger to see Xiang Yu, saying that Liu would become King of Guanzhong in accordance with King Huai II's earlier promise, while Ziying would be appointed as Liu's chancellor. Xiang Yu was furious after hearing that. At that time, he had about 400,000 troops under his command while Liu Bang only had a quarter of that number.

As strongly encouraged by his advisor Fan Zeng, Xiang Yu invited Liu Bang to attend a feast at Hong Gate and plotted to kill Liu during the banquet. However, Xiang Yu later listened to his uncle Xiang Bo and decided to spare Liu Bang. Liu Bang escaped during the banquet under the pretext of going to the latrine.

Xiang Yu paid no attention to Liu Bang's presumptive title and led his troops into Xianyang in 206 BC. He ordered the execution of Ziying and his family, as well as the destruction of the Epang Palace by fire. It was said that Xiang Yu would leave behind a trail of destruction in the places he passed by, and the people of Guanzhong were greatly disappointed with him.

Despite advice from his subjects to remain in Guanzhong and continue with his conquests, Xiang Yu was insistent on returning to his homeland in Chu. He said, "To not return home when one has made his fortune is equivalent to walking on the streets at night in glamourous outfits. Who would notice that?" One of his followers said, "It is indeed true when people say that the men of Chu are apes dressed in human clothing." Xiang Yu had that man boiled alive when he heard that insult.

Division of the empire

After the downfall of the Qin dynasty, Xiang Yu offered King Huai II the more honourable title of "Emperor Yi of Chu" and announced his decision to divide the former Qin Empire. Xiang Yu declared himself "Hegemon-King of Western Chu" (西楚霸王) and ruled nine commanderies in the former Liang and Chu territories, with his capital at Pengcheng. In the spring of 206 BC, Xiang Yu divided the former Qin Empire into the Eighteen Kingdoms, to be granted to his subordinates and some leaders of the former rebel forces. He moved some of the rulers of other states to more remote areas and granted the land of Guanzhong to the three surrendered Qin generals, ignoring Emperor Yi's earlier promise to appoint Liu Bang as king of that region. Liu Bang was relocated to the remote Hanzhong area and given the title of "King of Han" (漢王).

Xiang Yu appointed several generals from the rebel coalition as vassal kings, even though these generals were subordinates of other lords, who should rightfully be the kings in place of their followers. Xiang Yu also left out some other important rebel leaders who did not support him earlier, but did contribute to the overthrow of Qin. In winter, Xiang Yu moved Emperor Yi to the remote region of Chen, effectively sending the puppet emperor into exile. At the same time, he issued a secret order to the vassal kings in that area and had the emperor assassinated during his journey in 205 BC. The emperor's death was later used by Liu Bang as political propaganda to justify his war against Xiang Yu.

Shortly after the death of Emperor Yi, Xiang Yu had Han Cheng (King of Hán) put to death and seized Han's lands for himself. Several months later, Tian Rong (chancellor of Qi) took control over the Three Qis (Jiaodong, Qi and Jibei) from their respective kings and reinstated Tian Fu as the King of Qi, but he took over the throne himself afterwards. Similarly, Chen Yu, a former vice chancellor of Zhao, led an uprising against the King of Changshan, Zhang Er, and seized Zhang's domain and reinstalled Zhao Xie as the King of Zhao.

Chu–Han Contention

Battle of Pengcheng

In 206 BC, Liu Bang led his forces to attack Guanzhong. At that time, Xiang Yu was at war with Qi and did not focus on resisting the Han forces. The following year, Liu Bang formed an alliance with another five kingdoms and attacked Western Chu with a 560,000 strong army, capturing Xiang Yu's capital of Pengcheng. Upon hearing this, Xiang Yu led 30,000 men to attack Liu Bang and defeated the latter at the Battle of Pengcheng, with the Han army suffering heavy casualties.

Battle of Xingyang

Liu Bang managed to escape after his defeat with Xiang Yu's troops on pursuit. Han troops retreated to Xingyang and defended the city firmly, preventing Chu forces from advancing west any further, but only managed to hold on until 204 BC. Liu Bang's subordinate Ji Xin disguised himself as his lord and surrendered to Xiang Yu, buying time for Liu Bang to escape. When Xiang Yu learned that he had been fooled, he became furious and had Ji Xin burned to death. After the fall of Xingyang, Chu and Han forces were divided on two fronts along present-day Henan. However, Xiang Yu's forces were not faring well on the battlefront north of the Yellow River, as the Han army led by Han Xin defeated his troops in every single battle. At the same time, Liu Bang's ally Peng Yue led his men to harass Xiang Yu's rear.

Treaty of Hong Canal

By 203 BC, the tide had turned in favour of Han. Xiang Yu managed to capture Liu Bang's father after a year-long siege and he threatened to boil Liu's father alive if Liu refused to surrender. Liu Bang remarked that he and Xiang Yu were oath brothers, so if Xiang killed Liu's father, he would be guilty of patricide. Xiang Yu requested for an armistice, known as the Treaty of Hong Canal, and returned the hostages he had captured to Liu Bang as part of their agreement. The treaty divided China into east and west under the Chu and Han domains respectively.

Battle of Guling

Shortly after, as Xiang Yu was retreating eastwards, Liu Bang renounced the treaty and led his forces to attack Western Chu. Liu Bang sent messengers to Han Xin and Peng Yue, requesting for their assistance in forming a three-pronged attack on Xiang Yu, but Han Xin and Peng Yue did not mobilise their troops and Liu Bang was defeated by Xiang Yu at the Battle of Guling. Liu Bang retreated and reinforced his defences, while sending emissaries to Han Xin and Peng Yue, promising to grant them fiefs and titles of vassal kings if they would join him in attacking Western Chu.

Defeat and downfall

In 202 BC, Han armies led by Liu Bang, Han Xin and Peng Yue attacked Western Chu from three sides and trapped Xiang Yu's army, which was low on supplies, at Gaixia. Liu Bang ordered his troops to sing folk songs from the Chu region to create a false impression that Xiang Yu's native land had been conquered by Han forces. The morale of the Chu army plummeted and many of Xiang Yu's troops deserted in despair. Xiang Yu sank into a state of depression and he composed the Song of Gaixia. His wife Consort Yu committed suicide. The next morning, Xiang Yu led about 800 of his remaining elite cavalry on a desperate attempt to break out of the encirclement, with 5,000 enemy troops pursuing them.

After crossing the Huai River, Xiang Yu was only left with a few hundred soldiers. They were lost in Yinling (陰陵) and Xiang Yu asked for directions from a farmer, who directed him wrongly to a swamp. When Xiang Yu reached Dongcheng (東城), only 28 men were left, with the Han troops still following him. Xiang Yu made a speech to his men, saying that his downfall was due to Heaven's will and not his personal failure. After that, he led a charge out of the encirclement, killing one Han general in the battle. Xiang Yu then split his men into three groups to confuse the enemy and induce them to split up as well to attack the three groups. Xiang Yu took the Han troops by surprise again and slew another enemy commander, inflicting about 100 casualties on the enemy, while he only lost two men.

Death

Xiang Yu retreated to the bank of the Wu River (near present-day He County, Maanshan, Anhui) and the ferryman at the ford prepared a boat for him to cross the river, strongly encouraging him to do so because Xiang Yu still had the support of the people from his homeland in the south. Xiang Yu said that he was too ashamed to return home and face his people because none of the first 8,000 men from Jiangdong who followed him on his conquests survived. He refused to cross and ordered his remaining men to dismount, asking the ferryman to take his warhorse, Zhui (騅), back home.

Xiang Yu and his men made a last stand against wave after wave of Han forces until only Xiang himself was left alive. Xiang Yu continued to fight on and slew over 100 enemy soldiers, but he had also sustained several wounds all over his body. Just then, Xiang Yu saw an old friend Lü Matong among the Han soldiers, and he said to Lü, "I heard that the King of Han (Liu Bang) has placed a price of 1,000 gold and the title of "Wanhu Marquis" (萬戶侯; lit. "marquis of 10,000 households") on my head. Take it then, on account of our friendship." Xiang Yu then committed suicide by slitting his throat with his sword, and a brawl broke out among the Han soldiers at the scene due to the reward offered by Liu Bang, and Xiang Yu's body was said to be dismembered and mutilated in the fight. The reward was eventually claimed by Lü Matong and five others.

After Xiang Yu's death, Western Chu surrendered and China was united under Liu Bang's rule, marking the victory of the Han dynasty. Liu Bang held a grand state funeral for Xiang Yu in Gucheng (穀城; in Dongping County, Taian, Shandong), with the ceremony befitting Xiang's title "Duke of Lu". Xiang Yu's relatives were spared from death, including Xiang Bo, who saved Liu Bang's life at the Feast at Hong Gate, and they were granted marquis titles.

Depiction of character

Xiang Yu is depicted as a ruthless leader, ordering the massacres of entire cities even after they surrendered peacefully. This often led to cities putting up strong resistance, as they knew they would be killed even if they surrendered. The most notorious example of his cruelty was when he ordered the 200,000 surrendered Qin troops to be buried alive after the Battle of Julu, and the gruesome methods of execution he employed against his enemies and critics. In contrast, Liu Bang is portrayed as a shrewd and cunning ruler who could be brutal at times, but forbade his troops from looting the cities they captured and spared the lives of the citizens, earning their support and trust in return. Xiang Yu's story became an example for Confucianists to advocate the idea that leaders should rule with benevolence and not govern by instilling fear in the people. However, his ambitions ended with the collapse of Western Chu, his defeat by Liu Bang, and his death at the early age of around 30.

Song of Gaixia

The Song of Gaixia (垓下歌), translated as The Hegemon's Lament by Burton Watson, was a song composed by Xiang Yu while he was trapped by Liu Bang's forces at Gaixia.

The lyrics in English as follows are based on Burton Watson's translation:

Evaluation

The historian Sima Qian, who wrote Xiang Yu's biography in the Records of the Grand Historian, described Xiang as someone who boasted about his achievements and thought highly of himself. Xiang Yu preferred to depend on his personal abilities as opposed to learning with humility from others before him. Sima Qian thought that Xiang Yu had failed to see his own shortcomings and to make attempts to correct his mistakes, even until his death. Sima Qian thought that it was ridiculous when Xiang Yu claimed that his downfall was due to Heaven's will and not his personal failure.

Liu Bang's general Han Xin, who was one of Xiang Yu's opponents on the battlefield, made a statement criticising Xiang, "A man who turns into a fierce warrior when he encounters a rival stronger than he is, but also one who is sympathetic and soft hearted when he sees someone weaker than he is. Neither was he able to make good use of capable generals nor was he able to support Emperor Yi of Chu, as he killed the emperor. Even though he had the name of a Conqueror, he had already lost the favour of the people."

The Tang dynasty poet Du Mu mentioned Xiang Yu in one of his poems Ti Wujiang Ting (題烏江亭): "Victory or defeat is common in battle. One who can endure humiliation is a true man. There are several talents in Jiangdong, who knows if he (Xiang Yu) can make a comeback?" However, the Song dynasty poet Wang Anshi had a different opinion, as he wrote, "The warrior is already tired after so many battles. His defeat in the Central Plains is hard to reverse. Although there are talents in Jiangdong, are they willing to help him?" The Song Dynasty female poet Li Qingzhao wrote: "A hero in life, a king of ghosts after death. Until now we still remember Xiang Yu, who refused to return to Jiangdong."

Mao Zedong also once mentioned Xiang Yu, "We should use our remaining strength to defeat the enemy, instead of thinking about achieving fame like the Conqueror." In 1964, Mao also pointed out three reasons for Xiang Yu's downfall: not following Fan Zeng's advice to kill Liu Bang at the Feast at Hong Gate and letting Liu leave; adhering firmly to the terms of the peace treaty (without considering that Liu Bang might betray his trust); building his capital at Pengcheng.

Xiang Yu is popularly viewed as a leader who possessed great courage but lacked wisdom, and his character is aptly summarised using the Chinese idiom you yong wu mou (有勇無謀 yǒu yǒng wú móu), meaning "has courage but lacks tactics", "foolhardy". Xiang Yu's battle tactics were studied by later military leaders while his political blunders served as cautionary tales for later rulers. Another Chinese idiom, si mian chu ge (四面楚歌 sì miàn chǔ gē|l=surrounded by Chu songs), was also derived from the Battle of Gaixia, and used to describe someone in a desperate situation without help. Another saying by Liu Bang, "Having a Fan Zeng but unable to use him" (有一范增而不能用), was also used to describe Xiang Yu's reliance on his advisor Fan Zeng and failure to actually listen to Fan's advice.

Cultural references

Xiang Yu's might and prowess in battle has been glorified in Chinese folk tales, poetry, and novels, and he has been the subject of films, television, plays, Chinese operas, video games and comics. His classic image is that of a heroic and brave, but arrogant and bloodthirsty warrior-king. His romance with his wife Consort Yu and his suicide have also added a touch of a tragic hero to his character.

Poetry, folk tales, novels

Xiang Yu's might and prowess in battle appears in Chinese folk tales and poetry, e.g., in his final battle. The Meng Ch'iu, an 8th-century Chinese primer, contains the four-character rhyming couplet: "Ji Xin impersonates the Emperor". It referred to the episode in the Battle of Xingyang when Ji Xin and 2,000 women disguised themselves as Liu Bang and his army, to distract Xiang Yu in order to buy time for Liu Bang to escape from the city of Xingyang.

In Romance of the Three Kingdoms, one of the Four Great Classical Novels of Chinese literature, Sun Ce is nicknamed "Little Conqueror" (小霸王) and is often compared favourably to Xiang Yu by his contemporaries. Sun Ce is best known for his conquests in the Jiangdong region that laid the foundation of the state of Eastern Wu in the Three Kingdoms era. In Water Margin, another of the Four Great Classical Novels, Zhou Tong, one of the 108 outlaws, is nicknamed "Little Conqueror" for his resemblance to Xiang Yu in appearance.

In Jin Ping Mei, (Ci Hua edition) Xiang Yu (项籍) is mentioned as an example of a tragic character in the song at the opening of the first chapter.

The character Mata Zyndu in Ken Liu's epic fantasy novel The Grace of Kings is based on Xiang Yu.

Operas

A famous Beijing opera, The Hegemon-King Bids His Lady Farewell, depicts the events of Xiang Yu's defeat at the Battle of Gaixia. The title of the play was borrowed as the Chinese title for Chen Kaige's award-winning motion picture Farewell My Concubine.

生平

出身

項羽是項燕之孫，歷代習武，項氏多人也是楚國將領。項羽本人據載是目生重瞳，身長八尺，力能扛鼎，才氣過人。項羽少年時讀書輟學，學劍術也中途而廢。其叔父項梁因此不滿，項羽回答：「書足以記名姓而已。劍一人敵，不足學，學萬人敵。」於是項梁不教他讀書與劍術，改教他兵法，但項羽略知大意以後，便不肯全部學完。後來項梁因故殺人，躲避仇家，攜項羽逃亡到吳中（今蘇州）定居。

前223年，王翦率60萬大軍攻楚，項燕敗與秦軍被殺，楚亡。

秦始皇帝三十七年（公元前210年），秦始皇巡遊會稽郡渡錢塘江時，時年22歲的項羽跟項梁一起旁觀皇帝出巡，項羽說：「彼可取而代也」（我可以取代他。），嚇得項梁急掩其口，但從此對項羽另眼相看。該處一說名掩浦，一名項浦，位於湖州府城東北十六里弁山東，兩名皆與此典故有關。

起兵反秦（前209-前207）

秦二世元年（前209年）七月，陳勝、吳廣在大澤起義，開始反秦。到了九月，會稽郡假守殷通（代理太守）欲先發制人發兵反秦，於是找項梁商議。但項梁卻命項羽趁機謀殺了殷通，史書記載當時項羽在殷通府中拔劍斬其頭及擊殺門下近百人。項梁在吳中各縣自行舉兵起義反秦，不久便招募了精兵八千人，俗謂「八千江東子弟」。

項梁自封為會稽郡郡守，項羽則任裨將，率領八千子弟，渡長江，得到一些反秦軍隊歸附，兵力增至六、七萬人，進駐下邳，並消滅了自立為楚王的景駒勢力。范增進言楚地流行「楚雖三戶，亡秦必楚」之說，建議項梁立故楚後人為王，項梁採納，在民間找到楚懷王嫡孫熊心，立他為楚王，仍號「楚懷王」，即楚後懷王，以爭取楚地民心。

巨鹿之戰（前207）

項梁北伐秦兵，前208年九月在定陶之戰中遇秦兵主力章邯，陣亡。章邯其後率軍攻趙國，大敗趙軍，趙王趙歇退至巨鹿。楚後懷王遷都至彭城（今江蘇徐州），封項羽為長安侯，魯為其食邑，故項羽又稱魯公。懷王與諸將約定，「先入定關中者王之」，即先攻破關中者為關中王。項羽希望懷王命他攻關中，但懷王不聽，而命劉邦攻關中，命宋義為上將軍，項羽為次將，率兵往鉅鹿救趙。

宋義軍到達安陽後停止前進，在當地停留了四十六日。前208年十一月，項羽建議進兵，但宋義不接納，項羽便矯詔殺了宋義，楚軍諸將擁立羽為假（代理）上將軍。項羽派桓楚稟報懷王，懷王被迫任命項羽為上將軍。

項羽進兵巨鹿（今河北平鄉縣西南）。秦軍兵力有王離軍二十萬與駐守糧道的章邯軍二十萬，楚軍只有五萬，兵力遠遠少於秦軍。仔細考察形勢後，項羽決定先派英布、蒲將軍率兩萬楚軍渡漳河，襲擊秦軍糧道，令王離軍乏食，並使章邯軍疲於奔命，而能對王離軍各個擊破。項羽隨後率其餘4萬楚軍渡河，命令部下在渡河後砸碎釜鍋與鑿沉舟船（後世稱之為「破釜沉舟」，意謂豁出一切），全軍僅攜帶三日乾糧，餘者焚之，表明自絕退路，以示士卒必死，無一還心，若不得勝便有死無生。

最後項羽九戰九勝，楚軍無不以一當十，大破秦軍四十萬。當時帶領援兵的諸侯僅作觀戰（即成語「作壁上觀」），待章邯引兵退卻時，諸侯軍乃敢進攻王離、涉間，項羽轅門召見時，諸侯全部膝行而前，莫敢仰視。項羽成為「諸侯上將軍」，為各路諸侯軍隊的統帥。前207年六月，秦將章邯率所部向項羽投降。

進入關中（前206）

巨鹿之戰後，項羽繼續向關中進軍，前207年十一月（前207年12月14日–前206年1月11日），項羽擔心秦降兵生變，於是命楚軍在一夜間在新安城南（今河南省三門峽市義馬市二十里鋪村一帶）坑殺掉降兵二十餘萬人。但劉邦前207年十月已經搶先佔領秦都咸陽，並派軍在函谷關阻止楚軍入關，楚軍以英布為先鋒乃破關直入。劉邦大懼，乃退出咸陽，紮營灞上。劉邦的部下左司馬曹無傷派人向項羽說「沛公欲王關中，使子嬰為相，珍寶盡有之。」項羽大怒。當時項羽統率四十萬軍隊，而劉邦只得十萬人。范增遊說項羽鏟除劉邦，項羽在鴻門（今陝西省西安市臨潼區新豐鎮鴻門堡村）宴請劉邦，范增於席間命項莊借表演劍術為名，意欲刺殺劉邦，後世稱此為「項莊舞劍，意在沛公」。但項伯起身保護劉邦，又加上張良命樊噲衝進來遊說項羽，項羽讓劉邦平安地離去，後世稱此宴為「鴻門宴」。前206年，項羽進入咸陽後，殺秦王子嬰，焚咸陽秦宮室，大火維持三個月，他經過的地方「無不一片廢墟」，關中人民對他大為失望，不得民心。

分封天下（前206）

這時韓生勸說項羽留駐關中，可成就霸業。項羽沒有留在關中的打算，當時秦宮皆以燒而殘破，又思東歸，他說：「富貴不歸故鄉，如衣繡夜行，誰知之者。」此為成語衣錦還鄉和錦衣夜行的由來。韓生則因為項羽不留關中，批評項羽：「人言楚人沐猴而冠耳，果然。」（聽人說楚國人像是戴帽子的彌猴，果真如此。）項羽聽說後很生氣，烹殺了他。

之後項王使人致命懷王，請示如何分封領地。懷王曰：「如約。」即先入關中的劉邦為關中王。項羽不服，乃尊懷王為楚義帝，欲自己稱王，並分封各路將相：「天下初發難時，假立諸侯後以伐秦。然身被堅執銳首事，暴露於野三年，滅秦定天下者，皆將相諸君與籍之力也。義帝雖無功，故當分其地而王之。」（天下初發難時，我們暫立六國諸侯後代（即懷王）為王伐秦。然而親身披甲執銳起義，戰場奮戰三年，滅秦定天下的，是各位和我的力量啊。不過，義帝雖無功，我們還是分地讓他稱王。）諸將皆曰：「善。」

之後自立為「西楚霸王」，統治梁楚九郡，定都彭城（今江蘇徐州）。他把華夏大地分封給各路反秦將領，故秦關中之地，封給章邯、司馬欣、董翳三位秦朝降將，將劉邦封到漢中郡、巴郡、蜀郡、武都郡、廣漢郡當漢王。也大概在此時，為項羽帳下執戟郎的韓信因不受重用而棄楚投漢，日後成為楚漢戰爭中極關鍵的人物。

不久項羽把義帝流放至長沙國郴縣，暗命英布在半途殺死他。同年齊相國田榮起兵自立為齊王，又派兵支援陳餘擊敗常山王張耳，陳餘復立代王趙歇為趙王。

楚漢相持（前206-前204）

前206年8月，漢王劉邦趁項羽討伐齊地田榮時，反叛出兵攻擊三秦（即關中），擊潰楚軍，司馬欣、董翳降漢，章邯被圍困於廢丘，漢軍取得關中。此時韓王信攻韓地，再下十餘城，11月，韓王信受封韓王。漢軍取得關中與韓地，站穩腳跟，準備東進。

前205年4月，漢軍準備萬全，劉邦以項羽殺害楚義帝為名，聯合五國諸侯，兵分兩路，共五十六萬大軍進攻楚國，佔領彭城（今江蘇徐州），漢軍盡收貨寶美人，夜夜笙歌。項羽聞訊，命部屬留守齊地，親率三萬精兵南下。項羽所在的齊地位於彭城北方，項羽仔細考察形勢後，決定繞到彭城西邊，也就是從劉邦攻入彭城，防禦最薄弱的方向從背後予以奇襲。項羽行軍電光石火，先擊敗魯縣的樊噲，呂澤不及回防。項羽在早晨向彭城劉邦的數十萬漢軍發動進攻，至中午大破漢軍，將漢軍壓迫於谷、泗水地區，韓信等各路漢軍潰敗，被殲十餘萬人。楚軍收復彭城，又緊追不捨至睢水上（今安徽淮北市西），漢軍被逼入河中，溺斃十餘萬人，「睢水為之不流」。此時楚軍已經包圍劉邦三層，然而突然大風西北而起，飛沙走石，天昏地暗，楚軍大亂，劉邦趁機與數十騎逃走。太公呂后為楚軍所獲。此戰項羽以楚軍三萬擊潰漢軍五十六萬，為中國歷史上之名戰役。此一大敗讓漢軍元氣大傷，盡失原本佔領關中與韓地的優勢，退守滎陽。

敗逃的劉邦讓繒賀擊楚，阻止了楚軍進攻。。劉邦還派曹參平定了程處在燕縣的叛亂，楚柱天侯在衍氏的叛亂，樊噲在彭城之戰前失了魯地，戰後再次取得魯、梁一帶之地，最後灌嬰、靳歙、曹參、樊噲在「軍于滎陽」，即在滎陽會合。隨後引水灌廢丘，廢丘降，章邯自殺，消滅了章邯。接著劉邦稍收士卒，再加上蕭何亦發關中老弱，都到滎陽助軍，劉邦又以擔任過秦朝騎士的李必、駱甲兩人訓練騎兵。之後在京索打敗追擊的項羽，漢二年五月劉邦西收兵與呂澤在下邑會合。劉邦派人去沛縣找到了彭城之戰失散的劉盈和魯元公主。京索之戰，漢軍穩住陣腳，楚軍也無力突破漢軍防線進攻關中。雙方從此開始在滎、成一帶拉鉅，戰爭進入相持階段。

前204年，劉邦為解除滎陽相持的殭局，命令靳歙擊斷楚軍從滎陽至襄邑的糧道，命令灌嬰擊斷了楚軍從陽武至襄邑的糧道，離開滎陽，攻打楚國後方的二號大本營：魯城，並留下御史大夫周苛、魏王豹、樅公等人守滎陽，劉邦指揮的漢軍正在攻打魯城項冠。周苛認為魏王豹會投降項羽，殺了魏王豹，隨即項羽攻破了滎陽，烹殺了周苛，項羽再破成皋，至鞏縣，直逼洛陽，劉邦完全平定魯城，得知滎陽與成皋已失，項羽逼近洛陽，于是命令靳歙、丁複等單獨攻打楚國後方，丁複在彭城打敗龍且，劉邦與灌嬰回洛陽抵擋項羽，把項羽阻擋在鞏縣不能西進，項羽猛攻洛陽與敖倉，劉邦命令灌嬰去邯鄲調韓信軍回敖倉堅守，任命灌嬰接任御史大夫之職，派酈食其說降齊國。

劉邦在拖住項羽同時，另派數路漢軍分掠楚地，從後方包抄項羽，韓信、曹參、灌嬰、呂澤軍團等漢軍精銳在濰水之戰全殲了楚國大司馬龍且率領的援齊楚軍，平定齊國。彭越、劉賈在楚軍後方往來，斷絕楚軍糧食補給，而英布在楚國後方九江攻城略地，劉賈、盧綰也配合英布作戰。靳歙深入楚軍後方，平定楚國大片領土，東至平定繒、郯、下邳，南至蘄、竹邑，擊敗項悍於濟陽，從後方包圍項羽。灌嬰在淮北大破楚軍最後一支主力項聲軍團，攻下西楚都城彭城。對楚軍實現了戰略包圍，使項羽的處境更趨困難，楚軍糧食缺乏，既不能進，又不能退，完全陷入了困境。

兵敗陳垓（前203-前202）

前203年，漢軍士氣大盛，糧草充足，項王士卒疲憊，糧食告絕。項羽早先在彭城之戰擄獲劉邦之父劉太公、劉邦之妻呂雉，此時項羽以劉太公為人質要挾劉邦，但劉邦不理會。「我和你一起接受楚後懷王的命令，結拜為兄弟，我父親就是你父親；你一定要煮你父親來喫，也請分我一杯羹！」項羽大怒，原想殺了劉太公，但因項伯的勸阻而作罷。後來兩方簽訂鴻溝和約，項羽也釋放劉邦家人，率軍撤退。中國象棋棋盤上的「楚河漢界」，就是後人為了紀念此事而命名的。

不久劉邦從張良建議，撕毀和約追擊楚軍。劉邦趁項羽退軍之際率領漢軍發起追殲，在陽夏大破項羽率領的楚軍，俘虜楚國大將周將軍。劉邦到固陵後，命令劉賈渡淮河，攻下壽春，派人策反楚國大司馬周殷，攻占城父，並與灌嬰、靳歙約定好，在陳縣夾擊項羽，斷截項羽逃回會稽的歸路，漢將宣曲侯丁義率領騎兵和汾陽侯靳強率漢軍為先鋒，攻固陵楚軍，便擊破了楚大將鐘離眜的部隊，項羽得知灌嬰、靳歙等率領漢軍東來後，為防自己被包圍，集結著剩餘主力南退守至陳下。

前202年。這時候，楚軍東面喪失了龍且軍團、項聲軍團，西面喪失了曹咎軍團，南邊大司馬周殷也已叛楚率領軍團投降，漢將劉賈堵截項羽南逃之路，西楚主力基本損失殆盡。楚軍的糧草又被彭越截斷，人無糧、馬無草，危機重重。

劉邦面對大好形勢，毫不手軟，率領漢軍就主動出擊對陳縣的項羽軍發起追擊殲滅戰。陳下之戰項羽大敗，退逃東南，西楚陳公立即投向漢軍，陳縣歸于漢軍。項羽楚軍主力受到重創後欲撤往會稽，劉賈、周殷、英布攻下城父堵截項羽，項羽逃到垓下，劉邦與劉賈、周殷、英布會合。

韓信、彭越、英布等會合劉邦後，漢軍參戰兵力已超過六十萬人，在垓下將向江南撤退的十萬楚軍層層包圍，此險惡形勢即為後人所稱「十面埋伏」。劉邦以韓信親率三十萬人為前軍，孔將軍（孔聚）在左翼，費將軍（陳賀）在右翼，劉邦坐鎮居中軍在後，絳侯（周勃）、柴將軍（柴武）做為預備隊在劉邦軍後待命。彭越、英布等在楚軍後方，韓信親率前軍發動攻勢，初戰進攻受挫後退，在楚軍追擊時，劉邦讓孔、費兩翼左右包抄夾擊楚軍，同時韓信率領前軍翻身再戰，以及彭越、英布、劉賈、周殷等諸侯從各處圍攻楚軍，楚軍在三面夾擊中被擊敗。項羽被迫退回垓下城。

垓下之戰敗後，楚軍被包圍在垓下城。是夜，漢軍又以士兵以楚地方言唱歌，讓楚軍誤以為漢軍已渡江佔領了他們的家鄉，楚國已亡。這「四面楚歌」心理戰術，使項羽軍士氣崩潰。項羽和他愛人虞姬在此際唱出了著名的《垓下歌》，唱了一遍又一遍。項羽淚水流了下來，左右部將也泣不成聲，莫能仰視。項羽率剩餘精銳騎兵突圍。

項羽率八百餘人突圍，漢將灌嬰帶五千騎兵緊追不捨。渡過淮水以後，項羽的騎兵只剩下百人。項羽在陰陵迷路，向路邊的農夫問路，農夫謊報路徑，使項羽軍迷失在大澤當中，被漢軍追至，項羽引兵往東。

項羽到達東城時，只剩二十八騎，漢軍騎兵追擊的有數千人。項羽自度不得脫身。跟部將說：「吾起兵至今八歲矣，身七十餘戰，所當者破，所擊者服，未嘗敗北，遂霸有天下。然今卒困於此，此天之亡我，非戰之罪也。今日固決死，願為諸君快戰，必三勝之，為諸君潰圍，斬將，刈旗，令諸君知天亡我，非戰之罪也！」語畢，將二十八騎分為四隊四向。此時數千漢軍已重重包圍上來。項羽跟部將說：「吾為公取彼一將。」命令部將從四面分頭下山，約定在山東面三處會合。接著，項羽大吼著從山上殺向漢軍，望風披靡，如入無人之境，當場斬殺漢軍一將。當時，赤泉侯楊喜為騎將，追殺項羽，項羽沒出手，只回頭瞪眼暴喝一聲，赤泉侯即人馬俱驚，向後逃跑了好幾里遠。下山後，項羽與其騎會為三處。漢軍不知項羽所在，乃分軍為三，再包圍上來。項羽衝上前，再斬殺漢一都尉，又殺數十百人，再聚集部隊，只損失了兩名騎兵。項羽問部將：「何如？」部將皆拜服嘆曰：「如大王言。」

項羽原準備東渡烏江，回到故土江東。烏江亭長準備船給項羽，說：「江東雖小，地方千里，眾數十萬人，亦足王也。願大王急渡。今獨臣有船，漢軍至，無以渡。」項羽哈哈一笑：「天之亡我，我何渡為（為何渡）！且籍（項羽）與江東子弟八千人渡江而西，今無一人還，縱江東父兄憐而王我，我何面目見之？縱彼不言，籍獨不愧於心乎？（縱使他們不說，籍難道不愧於心？）」語畢，再跟亭長說：「吾知公（您）長者。吾騎此馬五歲，所當無敵，嘗一日行千里，不忍殺之，以賜公。」將愛馬烏騅託付給亭長後，項羽與騎兵下馬步行，持短兵與追上的漢軍接戰。獨項羽一人就殺死漢軍數百人。項羽亦身受十餘處傷。此時項羽看見從小一起長大的玩伴呂馬童也在漢軍中，說：「若非吾故人乎？」呂馬童不敢直視，轉頭背對項羽，跟另外一位軍官王翳說：「此項王也。」項羽說：「吾聞漢購我頭千金，邑萬戶，吾為若德（我送禮給你）。」於是自刎而死。王翳搶到項羽的頭，其他追兵為搶奪項羽屍體，光自相殘殺就殺死了數十人；最後郎中騎楊喜、騎司馬呂馬童、郎中呂勝及楊武各得一塊屍體。五人將屍體拼湊起來，確實是項羽。劉邦故將屬地分封為五：封呂馬童為中水侯，封王翳為杜衍侯，封楊喜為赤泉侯，封楊武為吳防侯，封呂勝為涅陽侯。

因項羽曾封魯公，故魯地（今山東曲阜一帶）一直不肯降漢，直到漢軍出示了項羽首級，並答允禮葬項羽才肯投降。之後，漢王劉邦在穀城（今山東省東平縣舊縣鄉）以魯公禮安葬項羽，並親為發哀，哭之而去。

後人

爭議

自殺地點

由於《史記·項羽本紀》、《史記·高祖本紀》及《漢書·灌嬰傳》有提及項羽「身死東城」、「追殺項羽東城」等，有人認為項羽是在東城自刎而不是烏江，但其觀點未有被廣泛接受。事實上，「東城自刎」、「烏江自刎」兩種說法並沒有矛盾，只是地方行政單位的級數不同。烏江即是烏江亭，在東城縣縣境。研究者指烏江亭可能因地處長江渡口、交通要津而設的亭。故完整的說法是：項羽于九江郡東城縣烏江亭自刎。

稱呼

關于項羽到底是「霸王」還是「項王」的稱呼，史書記載並不確定。根據《史記·項羽本紀》記載：「項王自立為西楚霸王，王九郡，都彭城。」，所謂「西楚霸王」在《項羽本紀》中就出現過這麼一次，此後不再出現「霸王」，而是稱項羽為「項王」。項羽最後在東城被圍，自己說：「吾起兵至今八歲矣，身七十餘戰，所當者破，所擊者服，未嘗敗北，遂霸有天下。」最後，太史公稱贊說：「夫秦失其政，陳涉首難，豪傑蜂起，相與並爭，不可勝數。然羽非有尺寸，乘勢起隴畝之中，三年，遂將五諸侯滅秦，分裂天下，而封王侯，政由羽出，號為『霸王』，位雖不終，近古以來未嘗有也。」

有意思的是《漢書·陳勝項籍傳》中，雖然幾乎是同樣的語言，卻沒有用「西楚霸王」，《漢書·陳勝項籍傳》：「羽自立為西楚伯王，王梁、楚地九郡，都彭城。」「然羽非有尺寸，乘勢拔起隴畝之中，三年，遂將五諸侯兵滅秦，分裂天下而威海內，封立王侯，政繇羽出，號為『伯王』，位雖不終，近古以來未嘗有也。」「霸」字變成了「伯」。

《史記考索·〈史記〉紀表書世家傳說例》記載：「項羽自為西楚霸王，霸者，『伯』之借字。伯，長也，猶言諸王之長也。羽既為諸侯長矣，故《本紀贊》曰：『分裂天下而封王侯，政由羽出，號為霸王。』」可見「西楚霸王」實為「西楚伯王」，意思就是諸侯之長。

評價

《史記》作者司馬遷在書中批評項羽：「吾聞之周生曰舜目蓋重瞳子，又聞項羽亦重瞳子。羽豈其苗裔邪？何興之暴也！夫秦失其政，陳涉首難，豪傑起，相與並爭，不可勝數。然羽非有尺寸乘埶，起隴畝之中，三年，遂將五諸侯滅秦，分裂天下，而封王侯，政由羽出，號為『霸王』，位雖不終，近古以來未嘗有也。及羽背關懷楚，放逐義帝而自立，怨王侯叛己，難矣。自矜功伐，奮其私智而不師古，謂霸王之業，欲以力征經營天下，五年卒亡其國，身死東城，尚不覺寤而不自責，過矣。乃引『天亡我，非用兵之罪也』，豈不謬哉！」。司馬遷評論前段部分肯定項羽之功績和勇猛，後半部分批評項羽驕傲自負，不善用人以及不省其過。但是，司馬遷在史記中仍然把項羽的傳記列為本紀，與歷代中國最高統治者平級，是少數享此殊榮而無帝王（皇帝）頭銜的人物。

認為是司馬遷怨恨晚年昏聵的漢武帝，所以故意把項羽這劉氏大敵地位提升，不然綜觀史記對項羽貶多於褒，不至於到本紀的高度，同時項羽為人好大喜功、極愛面子。《史記·項羽本紀》：「人或說項王曰：『關中阻山河四塞，地肥饒，可都以霸。』項王見秦宮室皆以燒殘破，又心懷思欲東歸，曰：『富貴不歸故鄉，如衣繡夜行，誰知之者！』說者曰：『人言楚人（暗指項羽）沐猴而冠耳，果然。』項王聞之，烹說者。」《史記·項羽本紀》記載了項羽對平民與降卒的六次大屠殺，全部都是戰勝之後駭人聽聞的屠殺與殺降：第一次襄城屠殺，坑殺全城平民；第二次城陽大屠殺，處決了此前幫助齊郡防禦的全城平民；第三次新安大屠殺，坑殺秦軍降卒二十萬；第四次咸陽大屠殺，殺戮關中平民無計，大燒大殺大劫掠大掘墓；第五次破齊大屠殺，坑殺田榮降卒數目不詳，大劫掠大燒殺，逼反復闢後的齊國；種種大規模暴行之外，項羽又恢復了戰國大煮活人的烹殺，後來又有殺楚懷王、殺秦王子嬰並秦諸公子、大掘秦始皇陵等，使大屠殺的酷烈惡風在秦末之亂中驟然暴長。

揚雄在《法言》中批判：「或問：「楚敗垓下，方死，曰『天也！』諒乎？」曰：「漢屈群策，群策屈群力；楚敦群策而自屈其力。屈人者克，自屈者負。天曷故焉！」」

楚國諸將：「項羽為人僄悍滑賊，諸所過無不殘滅。」（《史記·高祖本紀第八》）

陳平：「項王為人，恭敬愛人，士之廉節好禮者多歸之。至于行功爵邑，重之，士亦以此不附……項王不能信人，其所任愛，非諸項即妻之昆弟，雖有奇士不能用，平乃去楚。」

酈食其：「項王有倍約之名，殺義帝之負；于人之功無所記，于人之罪無所忘；戰勝而不得其賞，拔城而不得其封；非項氏莫得用事；為人刻印，刓而不能授；攻城得賂，積而不能賞：天下畔之，賢才怨之，而莫為之用。故天下之士歸于漢王，可坐而策也。」（《史記·酈生陸賈列傳第三十七》）

劉邦：「項羽有一范增而不能用，此其所以為我擒也！」（《史記·高祖本紀第八》）

韓信曾批評項羽為：「遇強則霸的匹夫之勇，和遇弱則憐的婦人之仁。既不能任用賢能將帥，又曾遷逐楚義帝，用兵趕盡殺絕。雖名為霸王，其實民心盡失。」；「請言項王之為人也。項王喑惡叱吒，千人皆廢；然不能任屬賢將，此特匹夫之勇耳。項王見人恭敬慈愛，言語嘔嘔，人有疾病，涕泣分食飲；至使人有功，當封爵者，印刓敝，忍不能予，此所謂婦人之仁也。」

此二句意為項羽只看眼前而不識大體；好行小惠而不願大封大賞，用人但憑個人好惡而非才學，只記過不記功且心胸狹隘，作風與劉邦完全相反。

高起、王陵對曰：「陛下慢而侮人，項羽仁而愛人。然陛下使人攻城略地，所降下者因以予之，與天下同利也。項羽妒賢嫉能，有功者害之，賢者疑之，戰勝而不予人功，得地而不予人利，此所以失天下也。」《高祖本紀》；陳平曰：「項王為人，恭敬愛人，士之廉節好禮者多歸之。至于行功爵邑，重之，士亦以此不附......項王不能信人，其所任愛，非諸項即妻之昆弟，雖有奇士不能用，平乃去楚。」《陳丞相世家》。此二句意指劉邦待人傲慢無禮，但用人不疑且封賞從不手軟；相較之下項羽仁而愛人，但用人疑神疑鬼且封賞極為小氣，無法留才。

王充：「項羽惡微，號而用兵，與高祖俱起，威力輕重，未有所定，則項羽力勁。」（《論衡·卷十九·恢國篇第五十八》）

劉劭：「若一人之身，兼有英雄，則能長世；高祖、項羽是也。然英之分，以多于雄，而英不可以少也。英分少，則智者去之，故項羽氣力蓋世，明能合變，而不能聽採奇異，有一范增不用，是以陳平之徒，皆亡歸高祖。」

段灼：「秦失其鹿，豪傑競逐，項羽既得而失之，其咎在烹韓生，而范增之謀不用。假令羽既距項伯之邪說，斬沛公于鴻門，都咸陽以號令諸侯，則天下無敵 矣。而羽距韓生之忠諫，背范增之深計，自謂霸王之業已定，都彭城，還故鄉，為晝被文繡，此蓋世俗兒女之情耳，而羽榮之。是故五載為漢所擒，至此尚不知覺悟，……甚痛矣哉！」（《晉書·卷四八·列傳第十八·段灼》）

唐代才子杜牧有詩《題烏江亭》：「勝敗兵家事不期，包羞忍恥是男兒。江東弟子多才俊，捲土重來未可知。」但是杜牧天真的想法被王安石仿此詩格式吐槽：「百戰疲勞壯士哀，中原一敗勢難回。江東子弟今雖在，肯與君王捲土來。」

宋蘇洵：「項籍有取天下之才，而無取天下之慮。」

宋蘇軾：「項籍唯不能忍，是以百戰百勝而輕用其鋒。」（《古文觀止》）

宋蘇轍《虞姬墓》的詠嘆是：布叛增亡國已空，摧殘羽翮自令窮。艱難獨與虞姬共，誰使西來敵沛公。

宋陸游《項羽》嘆曰：八尺將軍千里騅，拔山扛鼎不妨奇。范增力盡無施處，路到烏江君自知。

宋文天祥：「項籍、關侯、敖曹擒虎之流。」（《文山集·送彭叔英序》）

宋范浚：「若籍則無能有是，得范增不能用，得陳平不能用，得韓信不能用，皆使之怨僨棄去，徒以匹夫小勇，欲決雄雌于挑戰間，至力蹙勢窮，猶將馳殺一二漢將，以見枝能，此楚所以失天下也。然則籍之亡也，又胡望乎天哉？」

宋何去非：「項羽之于力嘗強矣，以其不知真力之所在，此所以亡。彼項羽以百戰百勝氣蓋于一時，手襲天下以王豪傑而宰制之，自以天下莫能抗也。觀其所賴以為資，蓋有類乎力者矣。雖然，彼之所謂力者，內恃其身之勇，叱吒震怒足以威匹夫；外恃其眾之勁，搏捽決戰足以吞敵人而已。至于阻河山，據形便，俯首東瞰，臨制天下，保王業之固，遺後世之強，所謂真力者，彼固莫或之知也。是以輕指關中天險之勢，燔燒屠戮逞其暴，卒舉而遺之二三降虜，反懷區區之故楚而甚榮。......惟其知奪而不知其有，此所以亡耳。」

宋代女詞人李清照詩讚云：「生當作人傑，死亦為鬼雄，至今思項羽，不肯過江東。」

明太祖朱元璋：「項羽南面稱孤，仁義不施，而自矜功伐。高祖知其然，承以柔遜，濟以寬仁，卒以勝之。」（《明史·卷第一三五·列傳第二三·孔克仁》）

王世貞：「嗟乎！古之有天下者，要必有人君之德，而其佐命以功臣終者，要必有人臣之體，人臣之體在才巨而心小其識不凡，而凡不遠而遠乃可保也無君德，而其材非人臣者。偏雄，則項羽、袁紹、李密；委質，則韓信及榮也。」（《王弇州崇論卷之四》）

李晚芳：「羽之神勇，千古無二；太史公以神勇之筆，寫神勇之人。亦千古無二。迄今正襟讀之，猶覺喑嗯叱吒之雄，縱橫馳騁于數頁之間，驅數百萬甲兵，如大風卷籜，奇觀也。」

明末流寇首領張獻忠曾經評歷代帝王，以西楚霸王為第一。

蔡東藩：「惟觀于項王之坑降卒，殺子嬰，弒義帝，種種不道，死有餘辜，彼自以為非戰之罪，罪固不在戰，而在殘暴也。彼殺人多矣，能無及此乎！天亡天亡，夫複誰尤！」

周恩來：「時勢之英雄，固若是其眾也，然非吾之所論于項羽、拿破崙也。夫二氏，世界之怪傑也。具併吞八荒之心，叱吒風雲之氣；勇冠萬夫，智超凡俗；戰無不勝，攻無不取；敵邦聞之而震魄，婦孺思之而寒膽；百世之下，猶懍懍有生氣，豈僅一世之雄哉！是猶其勇之著于外也。若其關係于世界之進退，人類之盛衰，又非一時豪俊、二三學者所可同日而語。雖以帝王之尊、宗教之力、金錢之勢，莫以易之。故二氏者，吾之所謂造時勢之英雄也。」

孫中山認為，項羽失敗最簡單原因，就是項羽專靠武力，劉邦入關之後，便約法三章，事事總是寬宏大量，以得民心為主。

中國共產黨領導人毛澤東有詞云：「宜將剩勇追窮寇，不可沽名學霸王。」在1964年的一次談話中，毛澤東進一步指出項羽戰敗的三個錯誤：鴻門宴不聽范增的話，放走劉邦；機械遵守鴻溝協定；以及建都徐州（當時叫彭城）。

藝術

文化影響

項羽英勇善戰但下場悲慘，加之他與虞姬的愛情故事，符合大眾對悲劇英雄的觀感而受戲劇與創作歡迎。

中國傳統戲曲中多有與項羽有關的內容，如近代京劇中有名劇霸王別姬。

由於項羽在江邊自盡，世人感念，建廟奉祀，陳朝時甚至尊封為帝。後人則尊為諸「水仙王」之一，希望項羽的英靈可以保佑漁民及水上運輸、貿易的安全。
