Henry the Fowler vs Yelu Abaoji

Henry the Fowler was elected King of East Francia by the Saxon and Frankish nobles at Fritzlar on May 6, 919. He was the first Saxon king, marking the transition from Carolingian to Ottonian rule. His election was contested by other dukes but he prevailed.

Henry the Fowler signed the Treaty of Bonn with Charles the Simple of West Francia, recognizing each other's royal titles and establishing peaceful relations. This treaty ended Carolingian claims over East Francia and solidified Henry's legitimacy as an independent king.

Henry the Fowler negotiated a nine-year truce with the Magyars, agreeing to pay tribute in exchange for a halt to their raids. He used this period to fortify towns, reorganize the army, and train cavalry. This strategic pause was crucial for his later military reforms.

Henry the Fowler's forces defeated a Slavic army at the Battle of Lenzen, securing the eastern frontier of East Francia. This victory allowed Henry to consolidate control over the Elbe region and establish the March of Brandenburg, a key step in German eastward expansion.

After the truce with the Magyars expired, Henry the Fowler led a German army to victory at the Battle of Riade (near Merseburg). The defeat of the Magyar cavalry ended their raids into East Francia for a generation and established Henry's reputation as a defender of Christendom.

Henry the Fowler died on July 2, 936, at Memleben. He was succeeded by his son, Otto I, who would become Holy Roman Emperor. Henry's reign laid the foundations for the Ottonian dynasty and the medieval German kingdom.

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.
