Reader's Guide

Emperor Taizu of Jin's significance lies in his role as the founder of the Jin dynasty, which ended Liao dominance in northern China and set the stage for later conflicts with the Song dynasty. He also established a feudal governmental system based on Jurchen tribal customs, organized agriculture under the Miŋgan Moumukə collectivist system, and ordered the creation of a unique Jurchen writing system. His alliance with the Northern Song dynasty, the Alliance Conducted at Sea, aimed to divide Liao territory, but after his death, the Jin turned against the Song.

Rise to Power and the Unification of the Jurchen Tribes

Born in 1068 along the Ashi River in present-day Harbin, Aguda descended from the most prestigious Jurchen line — an eighth-generation heir of Hanpu, the founding ancestor of the Wanyan clan. His father Helibo led the tribe, and his mother came from the Nalan chieftain's family. Aguda earned a reputation for personal bravery by fighting in numerous campaigns against rival Jurchen groups under Liao command. A crucial moment came in 1109, when a severe famine struck the region. Aguda and his father deliberately absorbed starving warriors from neighboring tribes, swelling the Wanyan ranks and forging deep loyalty that military force alone could not produce. By 1113, when he succeeded his elder brother Wuyashu as tribal leader, all Jurchen groups had been drawn under Wanyan authority. His stature among his people was sealed in 1112, when Liao emperor Tianzuo, on a fishing excursion through Jurchen territory, ordered every chieftain to dance before him. Aguda was the sole figure who refused, an act of defiance that spread rapidly and cemented his image as a leader unwilling to submit to Khitan arrogance.

The Military Overthrow of the Liao Dynasty

Aguda's open revolt against the Liao dynasty began in September 1114, when he mustered roughly 2,500 tribesmen at Liushui, near present-day Lalin River in Jilin Province. His chief strategists were Wanyan Zonghan and Wanyan Xiyin, who had guided his preparations, including the dispatch of spies into Liao territory in early 1114. The initial campaign was strikingly successful: Jurchen cavalry seized Ningjiangzhou and then routed a 7,000-strong Liao force at the Battle of Chuhedian in November. By January 1115, after a string of victories, Aguda proclaimed himself emperor, founded the Jin dynasty, and took the regnal name Shouguo. The scale of his military achievement grew dramatically that summer. In August 1115, his forces captured Huanglong Prefecture and then delivered a staggering blow at the Battle of Hubudagang, where 20,000 Jurchen horsemen shattered a Liao army reported at 700,000. By 1116 the entire Liaodong Peninsula was under Jin control. Between 1119 and 1122, Aguda's armies repeatedly defeated Liao forces and ultimately seized all five of the Liao dynasty's capitals, leaving the Khitan regime in terminal decline by the time of his death in August 1123.

State-Building and Institutional Foundations

Beyond his military conquests, Aguda devoted attention to constructing the administrative and cultural foundations of his new state. He established a feudal governmental structure rooted in Jurchen tribal customs, creating a system that blended indigenous tradition with the demands of ruling a multi-ethnic territory. A particularly significant innovation was the Miŋgan Moumukə, a collectivist agricultural organization that structured national farming and resource distribution along communal lines rather than purely individual ones. Recognizing the need for a distinct cultural identity, Aguda also absorbed selective elements of Han Chinese culture while simultaneously ordering his chancellor Wanyan Xiyin to develop a unique Jurchen writing system, ensuring the new dynasty would not be linguistically dependent on its neighbors. These institutional choices gave the Jin state a coherent internal framework even as it was still engaged in active warfare. Aguda's legacy in this regard was further solidified after his death: in 1145, his descendant Emperor Xizong posthumously bestowed upon him the temple name Taizu, formally enshrining him as the founding patriarch of the Jin imperial line.

Diplomacy, the Song Alliance, and Final Days

Because the Jin and Northern Song dynasties shared a common enemy in the Liao, the two powers moved toward cooperation. In 1117, Song envoys arrived under the pretext of purchasing horses, but their true purpose was to negotiate a military alliance. Between 1117 and 1123, seven Song delegations traveled to the Jurchens and six Jin embassies visited the Song capital at Bianjing, present-day Kaifeng. The result was the Alliance Conducted at Sea: the Song would attack the Liao from the south, and in exchange the Jin would cede the Liao's Sixteen Prefectures to Song control. Aguda's death in August 1123 came just months after the Jin and Song signed a treaty recognizing each other as equals, with the Song obligated to pay an annual tribute of 200,000 taels of silver and 300,000 bolts of silk. He was succeeded by his younger brother Wuqimai, who completed the Liao's destruction by capturing Emperor Tianzuo in 1125. Aguda was interred in the Rui Mausoleum at Dafangshan outside Zhongdu, modern Beijing. Today, mounted statues of Aguda and his commander Wanyan Zonghan stand on the grounds of the Jin Dynasty History Museum near Harbin, marking the former site of the old Jin capital, Shangjing.
