Emperor Yang Of Sui

Emperor Yang of Sui (, 569 – 11 April 618), personal name Yang Guang (), alternative name Ying (), childhood name Amo (), Xianbei name Puliuru Guang (), 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 (, in modern Yangzhou, Jiangsu), where he was eventually strangled in a coup led by his general Yuwen Huaji.
