Ashikaga Tadayoshi vs Geshu Han

Ashikaga Tadayoshi was appointed by his brother Takauji to a senior position in the newly established Ashikaga shogunate. He was tasked with overseeing civil administration and judicial matters, while Takauji focused on military affairs.

Tadayoshi governed Kyoto and managed the shogunate's civil affairs while Takauji campaigned against Emperor Go-Daigo's forces. He implemented policies to stabilize the capital and win support from the court nobility.

Tadayoshi's rivalry with Ko no Moronao, Takauji's favored general, escalated into open conflict. Tadayoshi accused Moronao of corruption and plotting against him, leading to a split within the Ashikaga leadership.

Tadayoshi raised an army and rebelled against his brother Takauji, allying with the Southern Court. The Kanno Disturbance (Kanno no Ran) erupted, a civil war within the Ashikaga shogunate that devastated Kyoto and weakened central authority.

Tadayoshi's forces were defeated by Takauji's army at the Battle of Uchino. He surrendered and was initially pardoned, but later died under suspicious circumstances, possibly poisoned on Takauji's orders.

Geshu Han commanded the Tang forces defending the strategic Tong Pass against An Lushan's rebel army. Despite initial success, he was forced to engage in open battle due to imperial pressure, leading to a disastrous defeat that opened the way to Chang'an.

After the defeat at Tong Pass, Geshu Han was captured by An Lushan's forces. He was subsequently executed by the rebels, marking the end of his military career and a major loss for the Tang loyalist cause.
