Sun Tzu

• 1. Introduction

  ›

  Sun Tzu supposedly summoned 180 of King Helü of Wu's concubines to a training ground and split them into two companies. He put the king's two favorite concubines in charge as commanders and gave the order to march. The women broke into laughter instead of obeying. Sun Tzu had the two commanders executed on the spot, despite the king's protests, and the rest fell into formation at once. This scene comes from the earliest surviving account of Sun Tzu's life, a biography written around 97 BC by the Han dynasty historian Sima Qian. Generations of scholars have since picked that story apart, along with nearly everything else claimed about Sun Tzu. Did a general by that name ever really give an order, let alone one that got two women killed? Did he write the book credited to him, The Art of War, or did he even exist? And how did a text whose true author might be a legend end up shaping warfare and strategy for millennia, reaching well beyond the battlefield?

• 2. A Question of Existence

  ›

  Sima Qian's biography places Sun Tzu as a minister to King Helü of Wu, dating his life to 544-496 BC. It says he was born in the state of Qi, in what is now Shandong province, near the end of the Spring and Autumn period. The scholar Victor Mair has called this account "essentially fictional." The name Sun Tzu, by which he is best known, is actually an honorific meaning Master Sun. His birth name was said to be Sun Wu, and after his death he was known by the courtesy name Changqing. A later Tang dynasty document from 812, the Yuanhe Xingzuan, claims his descendants lived in a place called Le'an. It offers no supporting evidence, and no place by that name existed before the Han dynasty.

  Beginning in the 12th century, during the Song dynasty, Chinese scholars started questioning whether Sun Tzu had existed at all. The scholar Ye Shi, who lived from 1150 to 1223, pointed out that the Zuo Zhuan never mentions Sun Tzu at all. That is notable because the Zuo Zhuan names most notable figures from the Spring and Autumn period. Sima Qian had claimed Sun Tzu proved his theories at the Battle of Boju in 506 BC. But the Zuo Zhuan, written centuries earlier and in far more detail, says nothing about him at all.

  The name Sun Wu itself does not appear in any text before the Records of the Grand Historian. Some scholars think it may have been an invented descriptive title meaning the fugitive warrior. The surname Sun can be glossed as a related word for fugitive. Wu was the ancient Chinese virtue of being martial and valiant, or in a Jianghuai dialect, a synonym for knight. That would fit Sun Tzu's role in the story of Wu Zixu, a refugee from the state of Chu. Zixu was credited with introducing Sun Wu to King Helü, and with writing another military text, the Wuzi. There are also no surviving records of professional generals from the Spring and Autumn period. Such roles only appear starting in the Warring States period, which raises doubt about Sun Tzu's rank. That confusion over names would resurface centuries later, when archaeologists dug up evidence of a second man who also went by Master Sun.

• 3. Two Men Named Sun

  ›

  Traditional accounts credit Sun Tzu's descendant, Sun Bin, with writing his own treatise on military tactics, also titled The Art of War. Classical Chinese texts referred to both men as Sun Tzu, so historians long assumed Sun Wu and Sun Bin were the same person. That assumption held until 1972, when construction workers at Yinque Shan in Shandong accidentally unearthed a cache of bamboo slips. The cache had been sealed sometime between 134 and 118 BC. Among the slips was Sun Bin's long lost Military Methods, a text Han dynasty bibliographies had attributed to one of Sun Wu's descendants.

  The same cache also held a version of The Art of War, covering roughly one third of the chapters in the modern text. Its wording matches the modern version closely. That timing supports a separate finding: the earliest layers of The Art of War likely date to a century after Sun Tzu supposedly lived. Anachronisms in the text include crossbows and other technology and military ideas that would not have existed in his era. In the early 20th century, the reformer Liang Qichao had already argued that Sun Bin wrote The Art of War in the 4th century BC. That specific theory is no longer considered credible. But researchers now think the Sun Wu and Sun Bin texts may represent a single, continuously developing tradition sharing the Sun name.

  Sun Bin, unlike Sun Wu, appears to have been a real person and a genuine military authority. Some historians now suspect Sun Bin may have inspired the legendary figure of Sun Tzu. That process, called euhemerism, elevates a real person into myth. The same discovery also explained why anecdotes attributed to Master Sun had always felt inconsistent: two separate men may have carried that title all along. Whichever man deserves the credit, the tradition that resulted would go on to lay out thirteen chapters of strategic doctrine.

• 4. Thirteen Chapters on War

  ›

  Thirteen chapters make up The Art of War, each devoted to a different set of skills tied to military strategy and tactics. The text took shape during the Warring States period, a stretch from 475 to 221 BC marked by constant conflict among rival Chinese states. Despite its subject, the book spends real space on diplomacy, arguing that cultivating relationships with other states is essential to a nation's health.

  According to the scholar Steven C. Combs, the book treats warfare as a metaphor for rhetoric, framing both as philosophically grounded arts. Combs describes the text's Taoist rhetoric as peaceful and passive, favoring silence over speech, in contrast to the more direct persuasion of Aristotelian rhetoric. That frugality, avoiding confrontation wherever possible, reflects a basic principle of Taoism running through the book's approach to conflict.

  The warlord Cao Cao wrote the earliest known commentary on The Art of War, in the early 3rd century. His preface admits that he edited the text and cut certain passages, though the scale of those changes remains unclear. In the 12th century, Ji Tianbao gathered Cao Cao's commentary with several commentaries, including work by Meng Shi, Li Quan, Du Mu, and Mei Yaochen. Most of those later commentaries added little to serious historical analysis. But scholarly interest in the text never let up, and copies eventually crossed the sea into Japan.

• 5. Spreading Beyond China

  ›

  The Art of War reached Nara Japan in the year 760, and Japanese generals quickly took to it. It later influenced the Sengoku period's so called Great Unifiers, Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu, playing a real role in Japan's eventual unification. After the Meiji Restoration, the book stayed popular within the Imperial Japanese armed forces. Admiral Tōgō Heihachirō, who led Japan's navy to victory in the Russo-Japanese War, was an avid reader of Sun Tzu.

  For nearly 1,500 years inside China, the text anchored an anthology that Emperor Shenzong of Song formally established as the Seven Military Classics, in 1080. Its road into the West started later. The French Jesuit priest Jean Joseph Marie Amiot translated it into French in 1772, with a second edition following in 1782. A partial English translation appeared in 1905, from the British officer Everard Ferguson Calthrop, under the title The Book of War. The first fully annotated English translation came from Lionel Giles, in 1910.

  Mao Zedong, the Chinese communist revolutionary, partly credited his 1949 victory over Chiang Kai-shek and the Kuomintang to lessons drawn from The Art of War. That influence carried into his own Little Red Book, which went on to shape communist insurgencies elsewhere. Ho Chi Minh had the text translated for his Vietnamese officers, and his general Võ Nguyên Giáp studied and practiced Sun Tzu's ideas closely. American generals Douglas MacArthur and Norman Schwarzkopf Jr. are also cited among those who drew on the book.

  In the 1987 film Wall Street, the character Gordon Gekko repeatedly quotes The Art of War as guiding principles for his aggressive trading. Admirers make a broader claim, that Sun Tzu's lessons apply to espionage, culture, governance, business, and sports, far beyond the battlefield it was written for. Centuries after a possibly fictional general supposedly gave orders inside a king's palace, his words were still being recited on a Hollywood trading floor.
