Charlemagne vs Wanyan Aguda

Charlemagne launched a series of campaigns against the Saxons lasting over three decades. He forcibly converted them to Christianity, incorporated their territory into the Frankish Empire, and ordered the execution of thousands at the Massacre of Verden in 782.

Charlemagne answered Pope Adrian I's call for aid against the Lombards. He besieged and captured Pavia, deposed King Desiderius, and annexed the Lombard Kingdom into his domain, assuming the title 'King of the Lombards' and solidifying Frankish control over Italy.

Charlemagne issued a series of legal and administrative reforms at the assembly in Herstal. He standardized weights and measures, reformed the coinage system, and strengthened the authority of royal officials (missi dominici) to oversee local governance and justice.

Charlemagne initiated a program of educational and cultural revival, inviting scholars like Alcuin of York to his court. He standardized Latin script (Carolingian minuscule), established palace schools, and promoted the copying of classical texts, preserving ancient knowledge.

Pope Leo III crowned Charlemagne as Emperor of the Romans in St. Peter's Basilica on Christmas Day. This act revived the Western Roman Empire, established a precedent for papal authority over imperial titles, and created a political entity that shaped medieval European politics.

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.
