During the Mongol siege of Xiangyang, Jia Sidao failed to send adequate reinforcements or supplies, despite the city's strategic importance. The siege lasted six years and ended with Xiangyang's fall in 1273, opening the Yangtze River to Mongol invasion.

Jia Sidao personally led the Song army against the Mongols at Dingjiazhou but was decisively defeated. After the battle, he was dismissed from office and later executed by his political enemies. His death marked the collapse of Song resistance.

Liu Jin gained the trust of the young Zhengde Emperor and became the most powerful eunuch in the court. He controlled access to the emperor and used his position to amass wealth and eliminate rivals.

Liu Jin revived and expanded the Eastern Depot, a secret police force under eunuch control. He used it to spy on officials and suppress dissent, creating a climate of fear in the Ming court.

After a rebellion against his rule, Liu Jin was arrested and sentenced to death by slow slicing. His execution marked the end of his dominance and was carried out publicly in Beijing.
