Emperor Wen of Sui vs Yelu Abaoji

Emperor Wen established a centralized bureaucratic system with three departments (Secretariat, Chancellery, and Department of State Affairs) and six ministries. This system became the foundation of Chinese government administration for centuries.

Emperor Wen, as a general of the Northern Zhou dynasty, forced the young Northern Zhou emperor to abdicate and proclaimed himself emperor of the Sui dynasty. This marked the beginning of the Sui dynasty, which would go on to reunify China.

Emperor Wen implemented the Equal-Field System, which distributed land to peasants based on the number of able-bodied men. This reform increased agricultural productivity, stabilized tax revenues, and reduced the power of large landowners.

Emperor Wen ordered the construction of a new capital city, Daxingcheng, near the old Han capital Chang'an. This city, later known as Chang'an, became a model for urban planning and served as the capital of the Sui and Tang dynasties.

Emperor Wen of Sui, as Emperor of Sui, launched a successful invasion of the Chen dynasty in the south, conquering it and reunifying China after nearly 300 years of division since the fall of the Western Jin. This ended the Northern and Southern Dynasties period.

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.
