In the Chanyuan Campaign he insisted that Emperor Zhenzong lead the army in person, leading to the Treaty of Chanyuan.

Life

Upright and outspoken

Kou Zhun passed the jinshi exam at 19 and was known as upright and outspoken; he once grabbed Emperor Taizong of Song's robe in the palace hall to make him hear out a remonstrance.

Chanyuan Campaign

In 1004 the Liao army advanced south in force. Some at court urged moving the capital to Jinling or Chengdu, but Kou Zhun, then chancellor, insisted that Emperor Zhenzong lead the campaign in person. When Zhenzong reached Chanzhou and mounted the tower of the northern city wall, Song morale soared; the Liao commander Xiao Talin was killed by a crossbow bolt, and the two sides concluded the Treaty of Chanyuan.

Died in exile at Leizhou

Later Wang Qinruo slandered Kou Zhun, saying he had used the emperor as a "last stake" in a gamble, and he was dismissed as chancellor. In 1022 he was pushed out by the powerful minister Ding Wei and demoted to revenue administrator of Leizhou, dying in exile the following year.

Legacy

Kou Zhun turned the tide when the state faced ruin, and the Treaty of Chanyuan brought more than a century of peace between Song and Liao.

Major works & achievements

Did you know? Wang Qinruo turned Emperor Zhenzong against him by calling his strategy "staking everything on a single throw," and that idiom comes from this episode.
