Rurik vs Wanyan Aguda

According to tradition, Rurik sent his lieutenants Askold and Dir to raid Constantinople. While the historicity is uncertain, this event is associated with the first Rus' attack on the Byzantine Empire, highlighting early Rus' expansion.

According to the Primary Chronicle, Rurik, a Varangian chieftain, was invited by Slavic and Finnic tribes to rule over them. He established his capital at Novgorod, founding the Rurik dynasty that would rule Kievan Rus' and later the Tsardom of Russia until 1598.

Rurik consolidated his rule over Novgorod and the surrounding territories, suppressing a rebellion led by Vadim the Bold. He established a centralized authority that became the basis for the early Russian state.

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.
