Emperor Taizu of Jin (August 1, 1068 – September 19, 1123), personal name Aguda, sinicised name Min (Chinese: 旻; pinyin: Mín), was the founder and first emperor of the Jurchen-led Jin dynasty of China. He was originally the chieftain of the Wanyan tribe, the most dominant among the Jurchen tribes which were subjects of the Khitan-led Liao dynasty. Starting in 1114, Aguda united the Jurchen tribes under his rule and rebelled against the Liao dynasty. A year later, he declared himself emperor and established the Jin dynasty. By the time of his death, the Jin dynasty had conquered most of the Liao dynasty's territories and emerged as a major power in northern China. In 1145, he was posthumously honoured with the temple name Taizu by his descendant Emperor Xizong.

The name [Wanyan] Aguda is transcribed [Wan-yen] A-ku-ta in Wade-Giles;^[1] the alternative spelling Akutta (possibly from reconstruction of Jurchen language) appears in a very small number of books as well.^[2][3]

Aguda was an eighth-generation descendant of Hanpu, the great progenitor of the entire Wanyan clan. His father was Helibo, the chieftain of the Wanyan clan. His mother was a daughter of the chieftain of the Nalan (拿懶 / 拏懶) tribe. He was born in 1068 near the Ashi River within present-day Harbin, Heilongjiang Province.^[4] He was well-known within his tribe for his bravery, and had participated in numerous campaigns against rival Jurchen tribes at the command of the Khitan-led Liao dynasty. In 1109, during the height of a widespread famine, Aguda assisted his father in absorbing famished warriors from other Jurchen tribes to strengthen his own tribe. Later, he fought wars against other Jurchen tribes and succeeded in unifying all Jurchens under the Wanyan tribe's leadership.

In 1113, Aguda succeeded his elder brother, Wuyashu, as the leader of his tribe. Like other Jurchens, Aguda loathed what he considered the exploitation of his tribesmen by corrupt Liao officials. In 1112, when the Liao ruler, Emperor Tianzuo, went on a fishing expedition in Jurchen territory, he ordered all the chieftains to dance for him. Aguda became famous among the Jurchens when he was the only person who defied the order.^[5]

In early 1114, Aguda sent spies into Liao territory and prepared to revolt against the Khitan regime, which he considered decadent. His chief advisors were Wanyan Zonghan and Wanyan Xiyin.^[6] In September, Aguda rallied his tribesmen (around 2,500 men) at Liushui (流水; near present-day Lalin River in Fuyu, Jilin Province) and openly rebelled against the Liao dynasty. His cavalry captured Ningjiangzhou (寧江州; present-day Fuyu, Jilin Province) and defeated a 7,000-strong Liao army at the Battle of Chuhedian in November. In January 1115, following a series of military successes, Aguda proclaimed himself emperor, established the Jin dynasty, and adopted the regnal name "Shouguo" (收國). In August, his army conquered Huanglong Prefecture (黄龍府; present-day Nong'an County, Jilin Province) and defeated 700,000 Liao troops with only 20,000 horsemen at the Battle of Hubudagang. By 1116, Aguda had completed the conquest of the entire Liaodong Peninsula. Between 1119 and 1122, his army repeatedly defeated Liao forces and captured all of the Liao dynasty's five capitals.

Since the Jin dynasty was an enemy of the Liao dynasty, the Han Chinese-led Northern Song dynasty considered the Jin dynasty to be their natural allies. In 1117, the Song dynasty sent emissaries to the Jin dynasty, ostensibly to buy horses, but in reality to negotiate an alliance against the Liao dynasty.^[7] Between 1117 and 1123, seven Song delegations visited the Jurchens, and six Jin embassies went to the Song capital, Bianjing (present-day Kaifeng, Henan Province).^[7] Between 1115 and 1123, the Jin and Song dynasties negotiated and formed the Alliance Conducted at Sea against the Liao dynasty. Under the conditions of the alliance, the Song dynasty would attack the Liao dynasty from the south, while in return, the Jin dynasty would hand over control of the Liao dynasty's Sixteen Prefectures to the Song dynasty.

During the war against the Liao dynasty, Aguda also took time to establish the new feudal governmental system based on Jurchen tribal customs. He also organised the national agriculture with a collectivist system known as the Miŋgan Moumukə (猛安謀克). Furthermore, Aguda absorbed elements of Han Chinese culture and ordered his chancellor Wanyan Xiyin to develop a unique Jurchen writing system.

Aguda died in August 1123, at the age of 56. His death came a few months after the Jin and Song dynasties signed a treaty which recognised each other as equals and required the Song to pay the Jin an annual tribute of 200,000 taels of silver and 300,000 bolts of silk.^[7] Aguda was succeeded by his younger brother, Wuqimai (Emperor Taizong). Wuqimai continued the campaign against the Liao dynasty and captured the Liao emperor, Emperor Tianzuo in 1125, thereby ending the Liao dynasty's existence. Soon after conquering the Liao dynasty, the Jin dynasty waged war against the Northern Song dynasty. Aguda was buried in the Rui Mausoleum (睿陵) at Dafangshan (大房山) outside Zhongdu (中都; present-day Beijing).

Mounted statues of Aguda and his chief commander, Wanyan Zonghan, have been erected on the grounds of the Jin Dynasty History Museum (金上京歷史博物馆) at the former location of the old Jin capital, Shangjing (上京),^[8] which is near present-day Acheng District, Harbin, Heilongjiang Province.
