Emperor Shirakawa vs Yelu Abaoji

Shirakawa abdicated the throne but continued to rule from a monastery as a cloistered emperor, creating the Insei system. This allowed retired emperors to wield real political power, bypassing the Fujiwara regents and dominating court politics for decades.

Shirakawa forced his son Horikawa to succeed him, overriding Fujiwara preferences. This conflict solidified the cloistered emperor's control over succession and reduced Fujiwara influence, leading to decades of political tension.

Shirakawa appointed Taira no Masamori as military governor of Ise Province, elevating the Taira clan's status. This move strengthened the imperial court's military capacity and laid the foundation for the Taira's later rise to power.

Shirakawa sponsored the construction and renovation of numerous Buddhist temples, including the Hossho-ji and Ensho-ji. This patronage strengthened the imperial family's religious authority and influenced Heian-period Buddhist art and architecture.

Yelu Abaoji was elected khagan of the Khitan tribes, unifying them under his leadership. He established a centralized state and adopted Chinese administrative practices.

Yelu Abaoji proclaimed himself emperor, founding the Liao dynasty. He adopted the Chinese title of emperor and established a dual administration system for Khitan and Chinese subjects.

Yelu Abaoji ordered the creation of a writing system for the Khitan language, based on Chinese characters. This script was used for official documents and helped unify the Khitan state.

Yelu Abaoji led a campaign that conquered the Korean kingdom of Bohai, incorporating its territory into the Liao empire. This expanded Liao's influence into Manchuria and Korea.

Yelu Abaoji died while returning from the conquest of Bohai. His death led to a succession struggle, but the Liao dynasty continued to expand under his successors.
