Ashikaga Yoshimasa vs Li Chengliang

The Onin War broke out in Kyoto during Yoshimasa's shogunate, triggered by a succession dispute. The war devastated Kyoto and marked the beginning of the Sengoku period, as Yoshimasa proved unable to control the warring factions.

Yoshimasa retired as shogun, handing power to his son Yoshihisa. His retirement was partly an attempt to end the Onin War, but the conflict continued, and Yoshimasa's withdrawal from politics weakened the Ashikaga shogunate.

Yoshimasa patronized the arts, fostering the development of the tea ceremony, flower arranging, Noh theater, and ink painting. His retreat from politics to cultural pursuits defined the Higashiyama period of Japanese aesthetics.

Yoshimasa began construction of the Silver Pavilion (Ginkaku-ji) in Kyoto. Though intended to be covered in silver foil, the project was never completed, but the pavilion became a symbol of Higashiyama culture and Japanese aesthetics.

Li Chengliang was appointed as the commander of the Liaodong military region, responsible for defending the Ming frontier against the Jurchen tribes. He held this post for decades, becoming the dominant military figure in the northeast.

Li Chengliang led a series of punitive expeditions against the Jianzhou Jurchens under Wang Gao, destroying their strongholds and killing thousands. These campaigns temporarily subdued the Jurchen threat but also fostered resentment.

Li Chengliang supported the young Jurchen leader Nurhaci, providing him with military backing and resources. This patronage inadvertently helped Nurhaci unify the Jurchen tribes, creating the future threat of the Later Jin dynasty.

Li Chengliang was accused of corruption, including embezzling military funds and accepting bribes from Jurchen leaders. His wealth and power grew unchecked, and he was criticized for prioritizing personal gain over frontier defense.

Li Chengliang retired from military service in his late 80s and died shortly after. His long tenure in Liaodong left a mixed legacy: he stabilized the frontier but also enabled the rise of Nurhaci, who would later overthrow the Ming.
