See it on the Battles & Wars map →What happened
Tradition says Sun Wu, called Sunzi or Sun Tzu ('Master Sun'), wrote it for King Helü of Wu around 500 BC. Most scholars now think it was compiled during the Warring States era, roughly 400–300 BC. Its core ideas: war is ruinous and a last resort, the best victory comes without fighting, all warfare is based on deception, and you must know both the enemy and yourself. It stresses planning, intelligence, supply and terrain over heroics.
Why it matters
It became East Asia's core military text, studied by Chinese, Korean and Japanese generals and by Mao Zedong, and is now read by Western officers and executives.
How we know
Later printed editions; an early version on bamboo slips found in a Han dynasty tomb at Yinqueshan, Shandong, in 1972; and Sima Qian's biography of Sun Wu.
Still debated
Whether Sun Wu existed, and whether one person wrote the book or it grew over generations, remain open questions.
Connections (4)
▸Sun Tzu's The Art of War was studied by generals during Warring States and the Qin unification of ChinaMostly agreed
The connection
The Art of War took shape during the Warring States era, when huge conscript armies made strategy, deception and supply essential. Military texts circulated widely: the philosopher Han Feizi wrote that every household kept the works of Sun and Wu, meaning Sunzi and the strategist Wu Qi.
When and how
China's warring kingdoms, roughly 400–221 BC; strategists, generals and rulers of Qin, Zhao, Qi and other states.
How sure are we?
Han Feizi's remark, Sima Qian's histories, and the Yinqueshan bamboo copy show the book was in wide circulation by Han times.
Debates and open questions
How much generals actually followed the text in battle, rather than quoting it, cannot be measured; the book may reflect these wars as much as shape them.
▸Sun Tzu's The Art of War shaped Mao's thinking on Guerrilla and insurgent warfareMostly agreed
The connection
Mao read classical Chinese strategy closely. In his 1936 essay on strategy he quoted Sun Tzu's maxim 'know the enemy and know yourself', and his guerrilla rules echo Sun Tzu's advice to avoid strength, strike weakness and use deception and speed. Mao blended these ideas with Marxism and his own fighting experience.
When and how
In Mao's essays written in northwest China, 1936–38, drawing on Sun Tzu's text, traditionally dated to about 500 BC.
How sure are we?
Mao explicitly quotes Sun Tzu in 'Problems of Strategy in China's Revolutionary War' (1936); the overlap of ideas is clear, though he drew on many sources.
Debates and open questions
How much Mao owed Sun Tzu, rather than popular novels such as Romance of the Three Kingdoms, Soviet doctrine or his own trial and error, is debated.
▸Sun Tzu's The Art of War is the classic Eastern counterpart to Clausewitz's On WarMostly agreed
The connection
They are the most-cited classics of strategy, from opposite ends of Eurasia. Sun Tzu stresses deception, intelligence and winning without fighting; Clausewitz stresses war's violence, friction and its service to politics. Clausewitz never read Sun Tzu as far as we know; scholars and staff colleges made the pairing later and now teach them side by side.
When and how
Sun Tzu's text dates to roughly the fifth to third centuries BC in China; On War to Berlin, 1832. The pairing spread in Western military education after Samuel Griffith's 1963 translation.
How sure are we?
This is a comparison, not a line of influence: nothing shows Clausewitz read the 1772 French translation. The two appear together on war-college reading lists.
Debates and open questions
Scholars argue whether the two really clash or mostly differ in emphasis; Michael Handel argued they agree more than they disagree.
▸Battle of Changping exposed a general versed only in texts like Sun Tzu's The Art of WarMostly agreed
The connection
At Changping, Zhao replaced its cautious veteran general Lian Po with Zhao Kuo, a young man famous for his book-learning in military texts. He left the defensive line and attacked. Qin's general Bai Qi feigned retreat, encircled him and starved his army. It became China's proverbial lesson that reading strategy is not practicing it.
When and how
Changping, in today's Gaoping, Shanxi Province, 260 BC; Zhao Kuo of Zhao against Bai Qi of Qin.
How sure are we?
Sima Qian's biographies of Bai Qi and of Zhao Kuo's father, Zhao She; the Chinese idiom 'discussing war on paper' comes from this story.
Debates and open questions
Sima Qian does not say which texts Zhao Kuo studied, and whether he was truly incompetent or trapped in an impossible position is debated.
