Chaos in the North: The Collapse of Northern Wei
While Emperor Wu of Liang busied himself with Buddhist ordinations in the south, the Northern Wei dynasty was tearing itself apart.
Under Emperor Xuanwu (r. 499–515), Buddhism flourished – temples multiplied, and the elite indulged in luxury. Heavy taxation bred deep resentment among the people.
When his son, the five-year-old Emperor Xiaoming, ascended the throne, real power fell to his mother, Empress Dowager Hu (Hu Chonghua) – a poet, archer, and shrewd politician who styled herself “Your Majesty” and ruled as de facto emperor.
As the boy grew, he resented her dominance. In secret, he summoned Erzhu Rong, chieftain of the Xiurong tribe (in modern Shanxi), whose forces had grown powerful after suppressing the Six Garrisons Uprising (523 CE) – a massive revolt by frontier soldiers in Woye, Huaishuo, Wuchuan, and three other northern garrisons.
But before Erzhu could arrive, Empress Hu poisoned her own son, installed a baby emperor, and tried to hold power.
Erzhu Rong saw his chance. Declaring vengeance for the murdered emperor, he marched on Luoyang with 8,000 cavalry. The empress fled to a nunnery – but Erzhu dragged her and the infant from their refuge, stuffed them into bamboo cages, and drowned them in the Yellow River.
He then enthroned Yuan Ziyou as Emperor Xiaozhuang and unleashed a massacre: over 2,000 officials were slaughtered in the palace courtyard. Erzhu became Prince of Taiyuan and Grand General Tianzhu – the true ruler of Wei.
The Emperor’s Revenge – and Its Price
Erzhu returned to Jinyang (modern Taiyuan), leaving puppets in Luoyang – including his daughter, now Empress. But Emperor Xiaozhuang chafed under this tyranny.
In 530 CE, he lured Erzhu to the capital under false pretenses – and killed him with his own hands.
The Erzhu clan retaliated instantly. Erzhu Shilong and Erzhu Zhao stormed Luoyang, executed the emperor, and installed puppet after puppet. The realm descended into chaos under their brutal, unlettered rule.
Among their generals, one man watched with growing disgust: Gao Huan.
Rise of a Survivor: From Border Orphan to Warlord
Gao Huan – also known by his Xianbei name Heluhun – was of uncertain ethnicity: possibly Han, possibly sinicized Xianbei. His ancestors had been exiled to Huaishuo Garrison (Inner Mongolia). Orphaned young, he was raised by a sister’s husband.
Handsome, eloquent, and cunning, he married into a Xianbei family and later served as a courier to Luoyang, where he witnessed court decadence firsthand. During the Six Garrisons Uprising, he joined the rebels – then switched allegiance to Erzhu Rong, who promoted him to Governor of Jin Prefecture (Linfen, Shanxi).
After Erzhu Rong’s death, Erzhu Zhao treated Gao as a sworn brother. But Gao secretly despised the Erzhus’ brutality – and dreamed of power.
His chance came when Erzhu Zhao complained about 200,000 displaced Six Garrisons soldiers now roaming Shanxi as starving refugees, constantly rebelling.
Gao proposed:”Appoint a trusted man to control them.”
When general Heba Yun suggested Gao himself, Gao feigned outrage, punched Heba in the mouth (knocking out a tooth), and cried:”Only the Great King may command such things!”
Flattered, Erzhu Zhao appointed him leader of the refugees.
The Great Deception: Crossing the Zhang River
Gao swiftly moved his followers to Huguan (eastern Shanxi), then requested permission to migrate east of the Taihang Mountains (“Shandong”) due to famine.
Erzhu Zhao agreed – unaware it was a ruse.
When rumors spread that Gao had seized 300 imperial horses, Erzhu chased him to the Zhang River – only to find the bridge washed out.
Across the flood, Gao pleaded loyalty. To prove trust, Erzhu rode alone across the river, handed Gao his sword, and bared his neck:”If you doubt me, cut my head!”
Gao wept dramatically:”I live only to serve you, Great King!”
The two swore oaths, shared a campfire – and Erzhu left, convinced of Gao’s fidelity.
But Gao knew: Erzhu Zhao was brave but foolish.
Forging an Alliance: The Gao Clan of Bohai
In Hebei, Gao’s disciplined troops won local support. He sought alliances with anti-Erzhu warlords – especially the Gao brothers of Xindu (Jizhou, Hebei): Gao Qian, his father Gao Yi, and fierce younger brother Gao Ang.
When Gao Qian arrived suspiciously, Gao Huan disarmed him with kinship:
“We’re both from Bohai Tiáo County! We share the same surname – I claim you as my clansman!”
Learning Gao Qian was technically his elder by generation, Gao Huan bowed and called him “Uncle” – delighting the proud warrior.
Only Gao Ang resisted – sending Gao Huan a woman’s skirt to mock his submission.
But Gao Huan sent his son Gao Cheng, who knelt and declared:”My father is your nephew; I am your grandnephew – accept my filial bow!”
Gao Ang relented.
Now united, the Gaos became Gao Huan’s most loyal commanders.
The Art of the Double Tongue
To rally his multiethnic army, Gao Huan mastered dual rhetoric:
To Xianbei soldiers:”Han are your slaves – they farm and weave for you. Why abuse them?”
To Han locals:”Xianbei are your guests – they protect you from bandits using your grain and cloth. Why hate them?”
This two-faced diplomacy forged fragile unity between conquerors and conquered – binding them to his cause.
Advisor Sun Teng urged:”Stop reporting to Luoyang. Proclaim your own emperor!”
So in 531, Gao installed Yuan Lang as puppet emperor and declared himself Grand Chancellor and Generalissimo – launching open war on the Erzhus.
The Battle of Hanling Mountain: Triumph Through Desperation
At Hanling Mountain (near Anyang, Henan) in 532, Gao faced Erzhu Zhao’s elite cavalry.
To eliminate retreat, Gao tethered oxen and donkeys across the road – forcing his men to fight or die.
Erzhu Zhao charged, shouting:”Heluhun! Traitor! What have I done to deserve this?”
Gao roared back:”You drowned emperors, butchered ministers, and starved the people! I fight for justice!”
Initial clashes went poorly – until Gao Ang’s cavalry smashed the Erzhu flanks. Disunited and demoralized, the Erzhu forces collapsed.
Erzhu Zhao fled to Jinyang – soon to die by suicide.
Meanwhile, Luoyang rebels killed Erzhu Shilong and surrendered the capital to Gao.
Master of the Realm
Gao entered Luoyang, deposed both puppet emperors, and installed Yuan Xiu – grandson of Emperor Xiaowen – as Emperor Xiaowu.
Offered the title “Grand General Tianzhu” (the same held by Erzhu Rong), Gao refused – it was cursed. He accepted only Grand Chancellor.
He stationed the Gao brothers in Luoyang but ruled from Jinyang, mirroring Erzhu’s model: emperor in name, warlord in truth.
The Erzhu clan was extinct. The Northern Wei was fractured. And Gao Huan, the orphan of Huaishuo, now held the dragon reins.
Yet his double-tongued empire – built on shifting loyalties and ethnic balancing – would not last. Within years, it would split into Eastern and Western Wei, setting the stage for the Northern Qi and Northern Zhou.
But that was a story for another day.
