Brief: This article recounts Emperor Yang of Sui’s rise to power and his reckless reign. After seizing the throne in suspicious circumstances, he launched massive projects including the Grand Canal and extravagant voyages to Jiangdu. His tyranny, forced labor, and costly wars sparked widespread uprisings, leading to the rapid collapse of the Sui Dynasty.
The Mysterious Death
In early 604 AD, Emperor Wen of Sui retreated to Renshou Palace for rest, only to fall gravely ill. With Empress Dugu having passed away two years prior, the aging Emperor, sensing his end was near, summoned Crown Prince Yang Guang and the powerful minister Yang Su to entrust them with state affairs. Yang Guang, eager to secure his succession, wrote to Yang Su inquiring about funeral arrangements. By a fatal error, this letter was delivered to Emperor Wen instead. Upon reading it, the Emperor was enraged, exclaiming, “They are wishing for my early death!”
At that moment, his beloved consort, Lady Chen, entered in tears. When asked what was wrong, she revealed that the Crown Prince had attempted to assault her earlier that day. Enraged by this moral depravity, Emperor Wen trembled, slapping his bed and shouting, “How can such a beast rule the empire! Dugu misled me; I have wronged Yang Yong! Summon Yang Yong immediately!” He intended to depose Yang Guang and reinstate his eldest son, Yang Yong, as heir.
However, it was too late. The news reached Yang Guang instantly. Conspiring with Yang Su, he ordered his personal guards to seal the palace gates and dispatched his confidant, Zhang Heng, into the Emperor’s chambers. Shortly after entering, Zhang Heng emerged crying, “The Sage has ascended; why have you not reported it?” Emperor Wen died under suspicious circumstances at the age of sixty-three, widely believed to have been murdered by Zhang Heng on Yang Guang’s orders. Yang Guang then ascended the throne as Emperor Yang (Sui Yangdi). To eliminate rivals, he promptly executed Yang Yong and his ten sons. When his fifth brother, Yang Liang (Prince of Han), revolted in Bingzhou upon hearing of their father’s suspicious death, Yang Guang crushed the rebellion, imprisoned Yang Liang, who soon died in captivity, mirroring the fate of his fourth brother, Yang Xiu.
Grand Projects and Human Cost
Aware of the public’s distrust, Emperor Yang sought to legitimize his rule through monumental projects. First, he ordered the construction of the Eastern Capital at Luoyang, claiming it was his father’s unfulfilled dream. Under the direction of Yuwen Kai, the city was completed in just ten months. Second, he initiated the massive excavation of the Grand Canal to connect the north and south, facilitating grain transport and enabling his own travel to Jiangdu (modern Yangzhou). Third, he launched three disastrous campaigns against Goguryeo in the northeast. Additionally, he built palaces, repaired the Great Wall, and expanded roads.
While ambitious, these projects ignored the suffering of the populace. Constructing Luoyang required over two million laborers monthly; nearly half died from exhaustion, with corpse-laden carts lining the roads. Massive timber pillars dragged from the south required thousands of men per log. The canal excavation claimed even more lives. With able-bodied men conscripted, agriculture collapsed as women, the elderly, and children were forced to till the fields; in some regions, women were also drafted. The human cost was catastrophic, yet Emperor Yang demanded ever faster progress.
The Illusion of Prosperity
Before Luoyang was fully complete, Emperor Yang moved the capital there and ordered the digging of a massive defensive moat, the “Long Qian,” believing himself secure. Shedding his previous facade of frugality, he indulged in extravagance. He expanded the imperial gardens, creating the Western Park, a 200-li enclosure filled with artificial landscapes. In winter, when leaves fell, artisans crafted colorful silk replacements to maintain the illusion of spring. He frequently hosted night banquets, accompanied by concubines riding horses and singing until dawn.
To impress foreign envoys, he ordered trees in Luoyang to be wrapped in silk and merchants to wear fine brocades. Restaurants were instructed to offer lavish meals for free, claiming, “We are so wealthy that we do not charge.” While guests were astounded, they remained unaware that the “generous” citizens who took free goods were merely actors who returned the items through back doors. This theatrical display of wealth masked the deepening poverty of the nation.
The Magnificent Fleet to Jiangdu
Growing tired of Luoyang, Emperor Yang prepared for his first voyage to Jiangdu in the autumn of 605 AD, even before the canal was fully finished. He ordered the construction of a colossal fleet. His personal “Dragon Boat” was a floating palace: 45 feet high, 200 feet long, and 50 feet wide, featuring four decks with over 160 rooms adorned with gold and jade. It required 1,080 boatmen to tow. Deeming the sight of semi-nude laborers undignified, he forced them to wear expensive silk robes and boots, earning them the title “Palace Feet.” Sweating profusely in the heavy garments, they suffered in silence. The Empress’s ship required 800 pullers, while over a hundred ships for concubines and ladies-in-waiting each needed hundreds more.
The entire procession included thousands of royal relatives, officials, monks, and nuns. Ships were ranked by size according to official status. Supply barges numbered two hundred. In total, over 80,000 boatmen pulled the fleet, which stretched for 200 li, resembling a swarm of locusts blotting out the horizon. On the banks, hundreds of thousands of cavalry troops provided escort, while local officials lined the river with colorful flags.
Extortion and Waste
The logistical burden on the populace was immense. Residents within 500 li of the canal were forced to supply the finest delicacies for the fleet. Farmers carried provisions from afar, only to have them rejected for minor flaws. Concubines ate only tiny portions, discarding the rest into massive pits dug daily for waste.
After two months, the fleet arrived in Jiangdu. There, Emperor Yang indulged in endless feasts and tours. Local officials competed to bribe him; promotions were granted based solely on the value of gifts. Wang Shichong, a low-ranking official, was elevated to command the military for presenting a bronze mirror and screen, while another official gained a prefecture for offering gourmet food.
After six months, the return journey to Luoyang was made overland, imposing further burdens. Thirty-six thousand yellow military flags were manufactured, and fresh, luxurious garments were required for the harem. Communities were taxed to provide rare materials like ivory, horns, and feathers, forcing people to hunt wildlife to extinction or buy up stockpiles at inflated prices. Tens of thousands of artisans worked overnight to meet these demands. Emperor Yang made two more trips to Jiangdu, each time draining the treasury and exhausting the people, squandering the wealth accumulated by Emperor Wen.
The Spark of Rebellion
The most devastating blow, however, was the three campaigns against Goguryeo. In 609 AD, Emperor Yang built the Linshuo Palace in Zhuo Commandery as a forward headquarters and ordered the construction of 300 warships in Laizhou. Laborers worked day and night in water, leading to festering wounds and maggot infestations; nearly half died before the ships were even launched. In total, hundreds of thousands perished from battle, exhaustion, disease, and execution.
Emperor Yang viewed human life as expendable. But the people, who had endured much, could endure no more. The relentless conscription, starvation, and brutality ignited a massive wave of popular uprisings across the empire. The Sui Dynasty, built on grandeur and blood, began to crumble under the weight of its own tyranny.
