Emperor Yang of Sui (Chinese: 隋煬帝, 569 – 11 April 618), personal name Yang Guang (楊廣), alternative name Ying (英), childhood name Amo (阿摩), Xianbei name Puliuru Guang (普六茹廣), was the second emperor of the Sui dynasty of China. Emperor Yang's original name was Yang Ying, but he was renamed by his father Emperor Wen, after consulting with oracles, to Yang Guang. Yang Guang was made the Prince of Jin after Emperor Wen established the Sui dynasty in 581. In 588, he was granted command of the five armies that invaded the Chen dynasty in southern China and was widely praised for the success of this campaign. These military achievements, as well as his machinations against his older brother Yang Yong, led to him becoming crown prince in 600. After the death of his father in 604, generally considered, though unproven, by most traditional historians to be a murder ordered by Yang Guang, he ascended the Sui throne. Emperor Yang, ruling from 604 to 618, committed to several large construction projects, most notably the completion of the Grand Canal, and the reconstruction of the Great Wall. He also ordered several military expeditions that brought Sui to its greatest territorial extent, one of which, the conquest of Champa, resulted in the death of thousands of Sui soldiers from malaria. These expeditions, along with a series of disastrous campaigns against Goguryeo, left the empire bankrupt and the populace in revolt. With northern China in turmoil, Emperor Yang spent his last days in Jiangdu (江都, in modern Yangzhou, Jiangsu), where he was eventually strangled in a coup led by his general Yuwen Huaji. Despite his accomplishments, Emperor Yang is generally considered by traditional historians to be one of the worst tyrants in Chinese history and the reason for the Sui dynasty's relatively short rule. His failed campaigns against Goguryeo, and the conscriptions levied to man them, coupled with increased taxation to finance these wars, and civil unrest as a result of this taxation, ultimately led to the downfall of the dynasty. 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. In 594, Yang Guang urged Emperor Wen to offer sacrifices to Mount Tai—a traditional ceremony for emperors, but one that was rarely carried out. Emperor Wen rejected the elaborate traditional ceremonies, but did carry out a reduced ceremony at Mount Tai. In spring 600, with Ashina Dianjue, who had by now become Tujue's khan, attacking the borders, Emperor Wen sent Yang Guang, Yang Su the Duke of Yue, Yang Guang's brother Yang Liang the Prince of Han, and Shi Wansui (史萬歲) the Duke of Taiping, against Tujue, and they were largely successful against Ashina Dianjue, protecting the Qimin Khan Ashina Rangan, whom Sui supported, from Ashina Dianjue's attack. By 600, Yang Guang's older brother Yang Yong had lost the favors of Emperor Wen and Empress Dugu—over his wastefulness (which displeased Emperor Wen) and his having many concubines (which displeased Empress Dugu). Yang Guang, by contrast, pretended to be frugal and loving only Princess Xiao. (It was written that Yang Guang did have concubines, but he pretended that he did not, and that he forced his concubines to have abortions if they became pregnant.) Yang Guang further inflamed Empress Dugu by informing her that she believed that Yang Yong was determined to kill him eventually. Empress Yang thus resolved to remove Yang Yong. Yang Guang further had his associate Yuwen Shu persuade Yang Su's brother Yang Yue (楊約) that, because Yang Su's relationship with Yang Yong was not good, that their family would be in peril should Yang Yong succeed Emperor Wen. Finally, Yang Guang also had Yang Yong's associate Ji Wei (姬威) accuse Yang Yong of plotting treason. Emperor Wen had Yang Su investigate, and Yang Guang and Yang Su manufactured evidence against Yang Yong. Emperor Wen deposed Yang Yong and replaced him with Yang Guang on 13 December 600, putting Yang Yong under house arrest under Yang Guang's watch. Yang Guang later prevented Yang Yong from all attempts of seeing his parents again. 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
