Wanyan Yongji

Biography

Princely Lineage and Early Career Wanyan Yongji, originally named Wanyan Yunji with the Jurchen personal name Xingsheng, was the seventh son of Emperor Shizong (Wanyan Yong). He grew into an imposing figure with a luxurious, flowing beard. Known for personal frugality, he disdained ornate personal silks and gold jewelry. Under Emperor Shizong and Emperor Zhangzong, Yongji lived as an unassuming imperial prince. In 1171 AD, he was created Prince of Xue, subsequently elevated to Prince of Sui, Prince of Lu, Prince of Han, and finally Prince of Wei. He served in various regional administrative commands at Daming, Kaifeng, and Beijing (Dading). In 1189, to respect the naming taboo of Emperor Xianzong (Wanyan Yungong), his personal name was officially altered from Yunji to Yongji. ### Succession Crisis and Imperial Accession In the winter of 1208 (Taihe 8), Zhangzong first appointed Yongji Military Commissioner of Wuding and then recalled him as an official of the princely establishment responsible for supervising the imperial clan. With two children still unborn, Zhangzong privately instructed him to make the sole boy heir if only one was male, or to select one if both were boys. Yongji agreed to preserve the succession within Zhangzong's line. In November 1208 AD (Taihe 8), Emperor Zhangzong died at the age of forty-one without surviving sons. Fearing dynastic instability, the inner court, led by Consort Li, the eunuch Li Xinxi, and Grand Councillor Wanyan Kuang, convened to select a successor. Viewing the mild-tempered Prince of Wei as manageable and non-threatening, they enthroned him as the seventh sovereign of Jin, inaugurating the Da'an reign era. However, Wanyan Yongji possessed no strategic vision or executive fortitude. Confronting a disintegrating fiscal apparatus, widespread rural uprisings, and internal factional corruption, the new Emperor appointed sycophantic courtiers, while ignoring warnings regarding the emerging storm across the Gobi Desert. ### The Insult of Genghis Khan and the Cataclysm of Yehuling Before attacking Jin, Genghis Khan attacked Western Xia, which requested Jin assistance. Yongji refused, and Western Xia submitted to the Mongols. In the spring of 1211 (Da'an 3), Yongji stationed troops north of the mountains to ambush the Mongol tribute party. Repeated warnings from Jin's jiu troops, drawn from Khitan and other northern peoples, led the Mongols to investigate and stay away. These forces were alienated from Jurchen rule and increasingly supported the Mongols. The failed ambush was followed by the end of tribute and a Mongol invasion. After Jin's defeat at Yehuling in August, Yongji wept with his ministers. In September he accepted advice to defend Zhongdu; its fortifications and garrison repelled the attack. In 1212, Genghis Khan again campaigned against Jin and won at Xijing. Yelü Liuge also rebelled in Liaodong, assembling more than 100,000 followers within months. He allied with the Mongols and defeated Jin troops at Dijinao'er, near modern Changtu in Liaoning, worsening Jin's position. The defining catastrophe of Wanyan Yongji's reign stemmed from his dealings with Genghis Khan. Years earlier, during Zhangzong's reign, when the Mongol tribes were nominal tributaries of Jin, Wanyan Yongji had been dispatched to the northern frontier at Jingshan to receive tribute. Observing his indecisive and servile demeanor, Genghis Khan took his measure with utter contempt. In late 1209 AD, following Wanyan Yongji's enthronement, imperial envoys arrived at Genghis Khan's camp to demand tributary oaths of allegiance. Learning that Yongji had assumed the Dragon Throne, Genghis Khan spat upon the southern ground and famously proclaimed to his assembly of chieftains: > "I thought the Emperor of the Central Plains was a celestial being appointed by heaven! How could a pathetic, cowardly weakling like him ever sit upon that throne? Why should I bow to such a dog!" Genghis Khan mounted his warhorse, rode away into the steppe, and terminated all tribute. In 1211 AD (Da'an 3), having mobilized 100,000 disciplined Mongol cavalry, Genghis Khan launched an all-out southern invasion to crush the Jin Empire. Confronting the invasion, Wanyan Yongji mobilized 400,000 elite Jurchen and auxiliary troops—the entire strategic field reserve of the empire—under Chancellor Wanyan Chengyu and general Wanyan Jiujin, deploying them across the mountain ridge at Yehuling (modern Wanquan, Hebei). In August 1211, the climactic Battle of Yehuling erupted. Genghis Khan ordered vanguard generals Muqali and Jebe to launch a ferocious frontal cavalry shock. Paralyzed by poor coordination and divided command, the Jurchen formations disintegrated under the Mongol charge. The battle turned into a historic slaughter: corpses covered the mountainous terrain for a hundred li, and the 400,000-man army was completely annihilated. Wanyan Jiujin was killed, and Chengyu barely escaped. ### The Fall of Juyong Pass and Internal Collapse Following Yehuling, the road to the North China Plain lay completely undefended. Jebe swept around the outer fortifications, capturing Juyong Pass. Mongol squadrons encircled the Central Capital (Zhongdu, modern Beijing). Inside the capital, panic reigned. Wanyan Yongji changed his era title to Chongqing in 1212 and Zhining in 1213, desperately ordering regional garrisons to relieve the siege. However, decades of ethnic resentment caused massive mutinies: Khitan and Han frontier garrisons defected en masse to Genghis Khan, severing communications between the capital and the northeastern ancestral homelands. ### The Palace Coup and Tragic End In August 1213 AD, General Hushahu (Heshelie Zhizhong), commanding the western defensive forces, abandoned his post after a defeat, leading several thousand mutinous troops in a frantic flight toward Zhongdu. Aware that cowardice in battle carried capital punishment, Hushahu staged a preemptive coup. Scaling the city walls at night, he murdered the loyal Chancellor Tudan Yi, captured the armories, and surrounded the imperial Forbidden City. Paralyzed by indecision, Wanyan Yongji offered no resistance. Hushahu burst into the imperial apartments, revoking Wanyan Yongji's imperial title and degrading him to Duke of Donghai. Confined to a private estate, Wanyan Yongji was murdered with poisoned wine on September 11, 1213 AD, by an imperial eunuch dispatched by Hushahu. Hushahu elevated Emperor Xuanzong (Wanyan Xun) to the throne. Xuanzong subsequently executed Hushahu, and in 1216 restored Wanyan Yongji posthumously as Prince of Wei with the posthumous name Shao. His disastrous five-year rule broke the military back of the Jurchen Empire, permanently initiating the death spiral that culminated in the Mongol conquest of North China.

Major Activities

Diplomatic Rupture with Genghis Khan In 1209 AD, upon ascending the throne, Wanyan Yongji sent envoys to Mongolia demanding traditional fealty. Having previously witnessed Yongji's personal cowardice during frontier tribute inspections, Genghis Khan spat upon the ground and declared him unfit for imperial majesty, severing tributary ties and launching the Mongol-Jin wars. ### The Catastrophe of Yehuling In the autumn of 1211 AD, facing Mongol invasion, Wanyan Yongji mobilized 400,000 elite troops at Yehuling. Due to rigid tactical deployment and failed operational reconnaissance, the entire army was annihilated by Genghis Khan, dissolving the strategic field army of the Jin Empire in a single engagement. ### The Coup of Hushahu and Demise In 1213 AD, failing to discipline mutinous commanders, Wanyan Yongji was cornered by rebel general Hushahu within Zhongdu. Overrun in his palace, he was deposed to Duke of Donghai and assassinated by poison, embodying the tragic collapse of late Jurchen imperial authority.

Historical Assessment

Official Dynastic Histories Tuotuo in History of Jin (Volume 13):

"Prince Shao of Wei reigned for five years. He possessed no monstrous personal vices, yet his character was mild and blind to opportunistic change. The martial valor of the ancient Jurchens had dissolved into languid weakness. When the Mongols struck, the imperial defenses shattered at Yehuling and were buried at Kuiguan, dissolving 400,000 elite warriors into dust. Murdered by the traitor Hushahu, how tragic! Though the state did not perish under his watch, the fatal tilt of the Jin ancestral altars truly began with Prince Wei!" Genghis Khan:

"I thought the Emperor of the Central Plains was a celestial being! How could a pathetic, cowardly weakling like him ever sit upon that throne? Why should I bow to him!" Emperor Xuanzong restored Yongji posthumously as Prince of Wei in 1216, with the posthumous name Shao. This is a summary of rather than a quotation of an imperial decree.
