Su Qin
Also known as Su Qin 苏秦

- Era
- Warring States; the dating of his career is disputed
- Role
- Diplomat credited with the vertical alliance against Qin
Su Qin is sold as the man who locked six states against Qin, but silk letters dug up in 1973 put his career later than that story.
Who was Su Qin?
Su Qin is the diplomat the Shiji credits with the vertical alliance, 合纵 (hézòng): a north–south pact of the six other Warring States against Qin. In that telling he is snubbed on his first tour, goes home to a family that will not feed him, studies until he can persuade kings, and ends by wearing the chancellors' seals of six states at once. The same chapter makes him a classmate of Zhang Yi under a master called Guiguzi. It is a superb story. It is not a safe chronology. The date used here, death about 284 BC, follows the revised career, not the Shiji's earlier one.
In 1973 excavators opened Han tomb 3 at Mawangdui and found a silk manuscript, the Zhanguo zonghengjia shu 战国纵横家书, letters and persuasions of the alliance advisers. Scholars using those letters argue that Su Qin was active later than Zhang Yi, in the politics of Yan and Qi, and that he died about 284 BC as Yan's general Yue Yi broke Qi. Zhang Yi was already dead in 309 BC. If that reading is right, the two men were not a matched pair of classmates running opposite plans in the same decade. The speeches in the Shiji and the Zhanguo ce remain the classic portrait: shaped rhetoric, with a life that stays hedged.
Key ideas
合纵
The vertical alliance
合纵 (hézòng) means joining the states that lay on a north–south line so none of them made a separate peace with Qin. On a map it is a coalition, and in the speeches it is a career.
连横
The rival horizontal policy
连横 (liánhéng), associated with Zhang Yi, cut the other way: each state dealt with Qin on its own. Su Qin's fame depends on this contrast, and the contrast is sharper in literature than in the revised dates.
The speech as a weapon
The vertical-alliance chapters treat a persuasive hearing as worth an army. They also show the weakness of that weapon, and a king who is talked into a pact can be talked out of it the next season.
Famous episodes
Six seals at one belt
LegendTraditional Shiji chronology
The Shiji has Su Qin, after years of rejection, talk the six states into one vertical league and hold all six chancellorships. The image is the whole myth in a costume. It is how he was remembered. It is not how the Mawangdui letters date his work, and the six seals belong to legend.
Classmates under Guiguzi
LegendTraditional
The Shiji makes Su Qin and Zhang Yi fellow students of Guiguzi, a master who is himself a shadowy figure. In the anecdote, Su Qin even pushes Zhang Yi towards Qin so that Qin will be frightening enough for the vertical league to seem necessary. The silk book makes a long joint career unlikely. The classmate story belongs in the legend column.
The Mawangdui letters move his life
HistoryLetters from the 3rd c. BC; found 1973
The silk manuscript from Mawangdui preserves alliance correspondence that the Shiji did not have. On the strength of it, modern scholars place Su Qin after Zhang Yi, inside the Yan–Qi struggle, and put his death near 284 BC, when Qi was broken. The famous rivalry may be partly a literary arrangement, and that is how it should be told.
Myths vs facts
Su Qin and Zhang Yi were classmates who personally duelled, pact against pact, for decades.
That is the Shiji's plot, complete with Guiguzi. The Mawangdui letters led scholars to a later Su Qin, active after Zhang Yi's death in 309 BC. A direct, lifelong duel is the part to hedge.
He really wore six chancellors' seals at the same time.
The six seals are the emblem of the legend. The vertical idea, a coalition against Qin, was a real diplomatic pattern. The costume in which one man embodies it is story.
The long speeches in the Zhanguo ce are transcripts of what he said.
They are set-piece persuasions. They show how Warring States rhetoric wanted kings to think. They are arguments in a tradition, not minutes and not a recording.
Takeaways
- Date the alliance before you copy its legend.
- Treat a strategy speech as rhetoric, not as minutes.
- Ask whether the two rivals even shared a decade.
