Emperor Yang of Sui

Background

Yang Guang was born in 569, during the reign of Emperor Wu of Northern Zhou. His parents were Yang Jian, the Duke of Sui, and Yang Jian's wife Duchess Dugu Qieluo; his maternal grandfather was Dugu Xin, a prominent military general and official. He was his parents' second son, after Yang Yong, and he had at least one older sister, Yang Lihua, who became the wife of Emperor Wu's crown prince Yuwen Yun (the later Emperor Xuan) in 573. He was considered handsome and intelligent in his youth, and of Yang Jian's and Duchess Dugu's sons, they favored him the most. Sometime during Northern Zhou, on account of Yang Jian's achievements, he was created the Duke of Yanmen.

In 580, Yang Jian seized power as regent after Emperor Xuan's death. In 581, he had Emperor Xuan's son (by the concubine Zhu Manyue), Emperor Jing, yield the throne to him, ending Northern Zhou and establishing the Sui dynasty as its Emperor Wen. Emperor Wen created Yang Yong crown prince and created his other sons imperial princes. Yang Guang thus received the title of Prince of Jin.

As Prince of Jin

Also in 581, Emperor Wen made Yang Guang the commandant at Bing Province (并州, roughly modern Taiyuan, Shanxi), in charge of the provinces north of the Yellow River. In 582, Emperor Wen set up a branch of the executive bureau of his government (尚書省; Shangshu Sheng) at Bing Province and made Yang Guang its head. He made the official Wang Shao (王韶) the deputy head and had him assist Yang Guang. Later in 582, Emperor Wen took a daughter of his vassal Emperor Ming of Western Liang (Xiao Kui) to be Yang Guang's wife and princess. It was said that Yang Guang loved and respected her.

In 584, after some Sui military and diplomatic victories, Tujue's Shabolüe Khan Ashina Shetu submitted to Sui. Yang Guang suggested to Emperor Wen that he rejected Ashina Shetu's overture and launch a major attack on Tujue, but Emperor Wen refused. In 585, with Ashina Shetu under attack from one of his subordinate khans, the Datou Khan Ashina Dianjue, Emperor Wen in fact sent Yang Guang to aid Ashina Shetu.

In 588, Emperor Wen moved Yang Guang's headquarters to Shouchun (壽春, in modern Lu'an, Anhui), and made him the commandant there as well as the head the branch of the executive bureau established there. In winter 588, Emperor Wen launched a major attack on the rival Chen dynasty. Yang Guang, his brother Yang Jun, and the general Yang Su were in command of the three main prongs of the operation, with Yang Guang in command of the eastern prong as well as the overall operation. The key official Gao Jiong served as Yang Guang's assistant. In spring 589, the generals Han Qinhu (韓擒虎) and Heruo Bi (賀若弼), both under Yang Guang, crossed the Yangtze River and approached the Chen capital Jiankang. Soon, after Heruo defeated the Chen general Xiao Mohe, Jiankang fell, and the Chen emperor Chen Shubao was captured. Yang Guang, apparently fascinated by Chen Shubao's favorite concubine Consort Zhang Lihua, sent Gao Jiong's son Gao Dehong (高德弘) to order Gao Jiong to hold Consort Zhang. Instead, Gao Jiong, comparing Consort Zhang to Daji (the wicked wife of Di Xin), beheaded her. Yang Guang thereafter resented Gao greatly, stating sarcastically, "It has been said, 'You should repay every good deed done to you.' I will repay Duke Gao later." By Yang Guang's orders, several of Chen Shubao's favorite officials, who were considered reasons for Chen's downfall, including Shi Wenqing (施文慶), Shen Keqing (沈客卿), Yang Huilang (陽慧朗), Xu Xi (徐析), and Ji Huijing (暨慧景), were executed. It was said that the people praised Yang Guang for his actions. Chen Shubao and his own clan members, however, were treated with kindness, and at Yang Guang's request, Chen Shubao sent letters to Chen generals who had not yet surrendered to persuade them to do so, and they largely did. Later that year, Yang Guang's forces escorted them to the capital Chang'an. At the ceremony to present Chen Shubao to Emperor Wen, Yang Guang marched into the palace first, and Emperor Wen bestowed on Yang Guang decorated wagons, horses, clothing, and jade. Afterwards, Yang Jun was given the Yang Province (then moved to modern Yangzhou, Jiangsu) commandant post, and Yang Guang was returned to Bing Province. In 590, Emperor Wen swapped the defense posts of Yang Jun and Yang Guang, returning Yang Guang to Yang Province.

As crown prince

It is widely believed that Yang Guang also continued to scheme to secure his status as the crown prince. Such commonly believed tales include the following:

By 602, his brother, Yang Xiu the Prince of Shu, who, was commandant of Yi Province (roughly modern Chengdu, Sichuan), and had great resources at his disposal. Yang Guang collected evidence of Yang Xiu's wrongdoing, particularly wastefulness, and had Yang Su submit them to Emperor Wen. Emperor Wen summoned Yang Xiu back to the capital and had Yang Su investigate, and both Yang Guang and Yang Su further manufactured evidence against Yang Xiu. Emperor Wen reduced Yang Xiu to commoner rank and put him under house arrest.

Also in 602, Empress Dugu died. It was said that Yang Guang pretended to mourn greatly, refusing most foods, but in private continued to dine normally.

In 604, while Emperor Wen was at his vacation palace Renshou Palace (仁壽宮, in modern Baoji, Shaanxi), he fell ill and then died—a death, however, that traditional historians, while admitting a lack of direct evidence, believed to be a murder ordered by Yang Guang (see below). Yang Guang, after sending Yang Yue to kill Yang Yong, announced Emperor Wen's death and took the throne as Emperor Yang.

Early reign

An immediate challenge that Emperor Yang faced was a rebellion by his brother Yang Liang, then the commandant at Bing Province, who was encouraged by the generals Wang Kui (王頍) and Xiao Mohe. Yang Liang received support from 19 provinces, but lacked a coherent plan as to whether to try to challenge Emperor Yang for the control of the entire empire, or just the region north of the Yellow River. After some initial successes, Yang Liang's offenses stalled. Emperor Yang sent Yang Su against him, and Yang Su proceeded quickly to Yang Liang's headquarters at Bing Province, capturing Xiao and forcing Yang Liang to surrender. Emperor Yang did not execute Yang Liang, but reduced him to commoner rank and imprisoned him for the rest of his life.

In winter 604, believing in the words of the sorcerer Zhangchou Taiyi (章仇太翼) that the geography of Chang'an was not conducive to his health, Emperor Yang went to Luoyang, designating it as the eastern capital, and would rarely return to Chang'an thereafter. He ordered that major construction projects be carried out at Luoyang, commensurate with the necessities of having it as the actual capital, and he left his oldest son, Yang Zhao the Prince of Jin, in charge of Chang'an. He conscripted several hundred thousands of young men to dig a lengthy trench to surround the Luoyang region, intending that it serve as a defense perimeter. He also ordered that women and servants be exempted from head taxes, and that men would only be considered adults (i.e., subject to conscription) when they turn 21.

In spring 605, Emperor Yang created his wife Crown Princess Xiao empress, and Yang Zhao as crown prince. He also abolished the offices of military commandants. He, at this time, trusted Empress Xiao's brother Xiao Cong the Duke of Ju (Western Liang's last emperor) and made him, as well as many of her other relatives, important officials, creating him the greater title of Duke of Liang.

Starting in 605, Emperor Yang also started a massive number of construction projects—including the building of the imperial palace at Luoyang, described to be particularly luxurious. Further, he conscripted a large number of men to build the Tongji Canal (通濟渠), connecting Luoyang with the Yellow River and connecting the Yellow River with the Huai River, as well as to rebuild the Han Canal (邗溝), connecting the Huai River and the Yangtze River. The two canals, which would eventually become parts of the Grand Canal of China, were said to be constructed within five months, but at substantial cost of life—40% to 50% of the men employed. Emperor Yang also ordered that some 40 secondary palaces be built around the empire, so that he could visit the various provinces, arguing that he needed to do so to see the conditions of the empire so that he could govern effectively.

Middle reign

In spring 609, Ashina Rangan made another visit to Emperor Yang, and Emperor Yang again rewarded him with much treasure.

Also in spring 609, Emperor Yang ordered a redistribution of the farming land throughout the empire.

Later in spring 609, Emperor Yang conducted a tour of the newly conquered Tuyuhun territory, and sent several generals to chase down Murong Fuyun. The Sui forces engaged Murong Fuyun's remaining forces, with mixed success, but Murong Fuyun was forced to flee to Dangxiang tribes. Emperor Yang tried to impose Murong Fuyun's son Murong Shun, whom Murong Fuyun had earlier sent to Sui as a hostage, as Tuyuhun's new khan, but the Tuyuhun people would not accept him, and Murong Shun was forced back to Sui territory. Emperor Yang also received 27 rulers of Xiyu kingdoms in an audience at Zhangye (張掖, in modern Zhangye, Gansu).

Later in the year, Ashina Rangan died, and was succeeded by his son Shibi Khan Ashina Duojishi. Pursuant to Tujue customs, Ashina Duojishi requested permission from Emperor Yang to marry Ashina Rangan's wife Princess Yicheng (義成公主) (the daughter of a clansman of Emperor Yang). Emperor Yang agreed. Also in 609, Emperor Yang, jealous of the literary talent of the official Xue Daoheng (薛道衡), he falsely accused Xue of defaming the emperor and had Xue strangled.

By this time, it was said that Emperor Yang's lifestyle had become particularly wasteful, and that he no longer felt bound by moral principles.

In 610, Emperor Yang visited Jiangdu again, and this time elevated Jiangdu's importance so that it effectively became a third capital.

When Emperor Yang was visiting Ashina Rangan in 607, a messenger from Goguryeo's King King Yeong-yang to Ashina Rangan happened to be present, and Ashina Rangan introduced him to Emperor Yang. Emperor Yang ordered King Yeong-yang to come visit him, offering to reward him if he did so and to punish him if he did not do so. King Yeong-yang did not respond, and by 611, Emperor Yang, insulted by the lack of response, prepared a campaign against Goguryeo. With Sui appearing to be in its prime, both governmental officials and the people were initially in support of a campaign to conquer Goguryeo. In spring 611, Emperor Yang went to Zhuo Commandery and announced the campaign against Goguryeo. Several hundred men were conscripted, and it was said that even before they could get to Zhuo Commandery, disease and fatigue had already caused much loss of life. In response, a number of conscripted soldiers deserted and became agrarian rebels.

Late reign

In spring 614, Emperor Yang again proposed another campaign against Goguryeo. Although his officials did not approve, none dared to oppose him. Many of the soldiers ordered to report to Zhuo Commandery deserted. Emperor Yang tried to stop desertions by executing those who deserted, but still could not stem the tide of desertions. Goguryeo forces had also been constantly ambushing the Sui army and the Sui supply line. Goguryeo offered peace, for Goguryeo had also been exhausted. Goguryeo also returned Yang Xuangan's associate Husi Zheng (斛斯政), who had fled to Goguryeo after his association with Yang Xuangan was discovered. Lai initially opposed ending the campaign, but did finally withdraw after ordered by Emperor Yuan. Emperor Yang executed Husi using the same kind of cruelty that he employed against Yang Jishan and Wei Fusi, but afterwards, when he again summoned Goguryeo's King Yeong-yang to meet him, King Yeong-yang again ignored him. Emperor Yang declared a fourth campaign against Goguryeo—but he never actually launched it. Meanwhile, agrarian rebellions continued to rise. While generals such as Zhang Xutuo and Wang Sichong enjoyed victories here and there, the situation was deteriorating for the welfare of the Sui state at large.

In spring 615, believing in accusations by Yuwen Shu that the official Li Hun (李渾) was intending to carry out a coup to replace Emperor Yang with his nephew Li Min (李敏, son-in-law of Emperor Yang's sister Yang Lihua the Princess Leping) and worried about prophecies that someone named Li would become the next emperor, Emperor Yang had Li Hun, Li Min, and their clansmen executed, and further poisoned Yang Lihua's daughter Yuwen Eying (宇文娥英).

Later in 615, Emperor Yang carried out a tour of the northern provinces with the Empress Xiao and much of the imperial court. Shibi Khan, angered that the imperial advisor Pei Ju had promised a princess to his brother Ashina Chiji (阿史那叱吉) and had executed his close advisor Shishu Huxi (史蜀胡悉) under false pretenses, launched a surprise attack on Yanmen Commandery. In accordance with Turkish customs, Princess Yicheng had married him as her husband's successor; having been well treated by the empress during an earlier visit, though, she sent a secret warning of his plans to the emperor and his wife. The imperial train sought refuge at the commandery seat in present-day Daixian, Shanxi, which Shibi Khan and his army put under siege on 11 September. It was said that Emperor Yang became so fearful that he cried all day long while holding onto his youngest son Yang Gao, the Prince of Zhao. Yuwen Shu suggested that Emperor Yang take the most elite guards and try to fight out of the siege, but Su Wei and Fan Zigai opposed this. Empress Xiao's brother Xiao Yu suggested seeking further help from Princess Yicheng, and Emperor Yang did so. Meanwhile, at Yu Shiji's advice, Emperor Yang also personally visited the soldiers defending the city, raising morale by promising to end the campaigns against Goguryeo and to reward them with honors and treasure. Princess Yicheng falsely informed Shibi Khan that the Turks were under attack from the north and relief troops from Luoyang and the other commanderies began arriving, so the khan lifted the siege. With the danger passed and credit muddled, Emperor Yang followed the advice of Su and Yuwen to renege on most of his promises: he did not return to the capital Chang'an, but went to Luoyang instead; he continued to prepare a campaign against Goguryeo; he did not bestow any monetary rewards on the garrison or its reinforcements; and he was sparing in the promotion of the officers involved. When Fan and Xiao Yu reminded him of the promises, Emperor Yang rebuked Fan and demoted Xiao Yu.

Patricide controversy

While no allegations were made at the time that Emperor Wen's death was anything other than the result of illness, starting from the time of the succeeding Tang dynasty, it was generally assumed that Emperor Wen was killed on Emperor Yang's orders—although more neutral historians generally assumed it to be true while stating that there was no direct evidence. An example is the Song dynasty historian Sima Guang's Zizhi Tongjian, generally considered one of the most reliable, albeit secondary, sources in Chinese history, which, after mentioning Emperor Wen's death and giving a commentary on Emperor Wen's reign, then gave this account:

After Empress Wenxian [(i.e., Empress Dugu)] died, Emperor Wen greatly favored both Consort Chen (the Lady Xuanhua) and Consort Cai (the Lady Ronghua). Consort Chen was the daughter of Emperor Xuan of Chen. Consort Cai was from Danyang [(丹楊, in modern Nanjing, Jiangsu)]. The Emperor grew ill at Renshou Palace, and was bedridden. Yang Su, the left head of the Shangshu Sheng, Liu Shu [(柳述)], the minister of defense [(Emperor Wen's son-in-law as the husband of his daughter Yang Awu (楊阿五) the Princess Lanling)], and Yuan Yan [(元巖)] the court administrator, were all attending to him. The Emperor ordered the Crown Prince to enter the palace to stay at Dabao Hall [(大寶殿)]. The Crown Prince thought that precautions needed to be taken in case of the Emperor's death, and therefore he personally wrote a secret note to inquire of Yang Su what precautions to take. Yang Su wrote a return note detailing his security precautions, but by error the palace attendants delivered it to the Emperor. The Emperor was greatly displeased. Further, one morning, Consort Chen was going to the latrine. Yang Guang could not resist her beauty, and grabbed her, wanting to have sexual relations with her. She resisted and fled back to the Emperor. The Emperor was surprised by her anxiety and asked her; she shed tears and stated, "The Crown Prince was being indecent to me." The Emperor was shocked and angry, pounding the bed and stating, "Animal! How can I give him the important affairs? Dugu destroyed me!" He then summoned Liu and Yuan, telling them, "Summon my son!" They were about to summon the Crown Prince when he clarified, "Yang Yong!" Liu and Yuan left the palace to write the edict. When Yang Su heard this, he reported to the Crown Prince, and thereafter an edict of the Emperor was forged to arrest Liu and Yuan and detain them at the jail at the Supreme Court. The guards of the Eastern Palace [(i.e., the Crown Prince's guards)] were summoned to take over security from the Renshou Palace guards. Security measures were instituted to disallow entry into or exit out of the palace. Yuwen Shu and Guo Yan [(郭衍)] were put in command. Further, the deputy chief of staff for the Crown Prince's palace, Zhang Heng [(張衡)] entered the Emperor's palace to attend to his medical needs. Zhang expelled all of the ladies in waiting and the eunuchs. Soon thereafter, the Emperor died. Thereafter, there were different views as to how he died. When Consort Chen and the other women of the palace heard of this, they stared at each other in fear and shook with fear. At dusk, the Crown Prince sent a eunuch with a small gold box, personally sealed by the Crown Prince, to be delivered to Consort Chen. When Consort Chen saw it, she, believing that there was poison inside, was very fearful, and did not dare to open it. Only after the eunuch urged her did she open it. Instead, the box contained several tongxin knots [(同心結, a decoration showing love)]. Her ladies in waiting were relieved and became happy, stating to each other, "Finally, death is avoided." Consort Chen, in shame and anger, sat down and refused to accept the box. The ladies in waiting forced her to bow to the eunuch. That night, the Crown Prince ordered Consort Chen to have sexual relations with him.

Tomb

In April 2013 the tomb of Emperor Yang was discovered in Hanjiang, Yangzhou. Two brick-lined tombs were discovered in the Hanjiang District of Yangzhou during work on a housing development. A stone epitaph found in the western tomb was inscribed with the title "Tomb epitaph of the late Emperor Yang of Sui" (隋故煬帝墓誌), indicating that the tomb was that of Emperor Yang. It is thought that the other tomb may be that of the emperor's consort, but it has not yet been properly excavated.

The tomb is 4.98 × 5.88 meters in dimension, which is smaller than many non-royal tombs of the period. The reason for the tomb's small size according to Chinese archaeologists is that the emperor died suddenly when he escaped to Yangzhou during a coup, and there was no time to build a grand tomb.

The top of the tomb had been damaged by later buildings built on top of it, and the tomb had been robbed in antiquity. No coffin or human remains have been found in the tomb, but a number of artefacts have been recovered, including a pair of lion-shaped gold-inlaid iron door-knockers and a jade belt with gold decoration.

Arts

Emperor Yang was also a patron of the arts, having expanded the number of foreign orchestras (from across Asia) at the Sui court from seven to nine. He was, in fact, quite a gifted artist himself, but one prone to horrible fits of jealousy and stubbornness, who seldom listened to the advice of more talented individuals. He was a talented poet but killed two poets after he found their stanzas to be superior to his own.
