Kou Zhun

Kou Zhun, as chancellor, persuaded Emperor Zhenzong to personally lead the Song army against the invading Liao forces. The emperor's presence at the front boosted morale and led to a stalemate that forced the Liao to negotiate.

Kou Zhun played a key role in negotiating the Treaty of Chanyuan with the Liao dynasty. The treaty established a peace agreement where Song paid annual tribute to Liao, ending decades of war and securing a century of peace.

Kou Zhun was exiled to Leizhou in southern China after losing a power struggle at court. His removal from power marked the end of his influence and reflected the factional conflicts of the Song court.
