- Yang Zhao
Yang Zhao (楊昭) (579-606), formally Crown Prince Yuande (元德太子, literally "the discerning and nurturing crown prince"), posthumously honored as Emperor Xiaocheng (孝成皇帝, literally "the filial and successful emperor") with the
temple nameShizong (世宗) during the brief reign of his son Yang Tong, was a crown princeof the Chinese dynasty Sui Dynasty. He was the oldest son of Emperor Yang (Yang Guang) who predeceased his father.
Yang Zhao was born in 579, while his father Yang Guang was the Prince of Jin under his grandfather Emperor Wen. His mother was Yang Guang's wife Princess Xiao, and he was their oldest son. In his infancy, he was raised by his grandparents Emperor Wen and
Empress Dugu Qieluo. In 590, Emperor Wen created him the Prince of Henan. He initially married the daughter of the official Cui Hongsheng (崔弘昇) as his wife and princess, but after Princess Cui's aunt, who married his uncle Yang Jun the Prince of Qin, was discovered to have poisoned Yang Jun over her jealousness for Yang Jun's concubines in 597, Yang Zhao divorced his wife and married the daughter of the official Wei Shou (韋壽) the Duke of Hua as his wife and princess. After his father Yang Guang displaced his uncle Yang Yongas crown prince in 600, Yang Zhao was created his father's old title of Prince of Jin in 601.
As crown prince
In 604, Emperor Wen died -- a death that most traditional historians believed to be a murder ordered by Yang Guang, but admitted a lack of direct evidence -- and Yang Guang took the throne as Emperor Yang. Soon, believing the words of the sorcerer Zhangchou Taiyi (章仇太翼) that the geography of the region surrounding the capital
Chang'anwas unsuitable for him, Emperor Yang took up residence at Luoyangand made it the eastern capital. He left Yang Zhao in charge at Chang'an. In spring 605, Emperor Yang created Yang Zhao crown prince. Emperor Yang considered restoring Princess Cui, but when he sent a messenger to the house of Princess Cui's uncle Cui Hongdu (崔弘度) to discuss the matter, Cui Hongdu did not realize that an imperial messenger had arrived and therefore did not respond. Emperor Yang was displeased, and the matter was not again discussed.
In 606, Yang Zhao went to Luoyang to greet his parents, and he spent several months there. He requested permission to remain longer at Luoyang, but Emperor Yang denied it. Meanwhile, because he was required to kneel before his father and had to do so repeatedly while at Luoyang, and he was severely overweight, he became ill from the fatigue, and he died in summer 606. When his son
Yang Tonglater took the throne in 618 during the dynasty's disintegration, he was posthumously honored as an emperor.
