Henry the Fowler vs Wanyan Aguda

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.

Aguda's Jurchen forces defeated a Liao army at Hubudagang, marking the first major victory of the rebellion. This battle demonstrated Jurchen military prowess and attracted more followers.

Wanyan Aguda united the Jurchen tribes under his leadership, creating a confederation that rebelled against Liao domination. He organized a disciplined army and began the Jurchen revolt.

Wanyan Aguda proclaimed himself emperor, founding the Jin dynasty. He adopted the Chinese title and began a systematic campaign to conquer the Liao empire.

Aguda's forces captured the Liao supreme capital Shangjing, dealing a severe blow to the Liao dynasty. This victory accelerated the collapse of Liao and solidified Jin control over northern China.

Aguda formed an alliance with the Northern Song dynasty to jointly attack the Liao empire. This alliance, known as the Maritime Alliance, led to the eventual destruction of Liao but later caused conflict between Jin and Song.

Wanyan Aguda died, and his brother Wanyan Wuqimai succeeded him. Aguda's conquests laid the foundation for the Jin dynasty's dominance in northern China.
