Emperor Wen of Sui

Emperor Wen of Sui (隋文帝; 21 July 541 – 13 August 604), personal name Yang Jian (楊堅), Xianbei name Puliuru Jian (普六茹堅), alias Narayana (Chinese: 那羅延; pinyin: Nàluóyán) deriving from Buddhist terms, was the founder and first emperor of China's Sui dynasty (581–618 AD). He was a hard-working administrator and a micromanager. The Sui Shu records him as having withdrawn his favour from the Confucians, giving it to "the group advocating Xing-Ming and authoritarian government." As a Buddhist, he encouraged the spread of Buddhism through the state. He is regarded as one of the most important emperors in ancient Chinese history, reunifying China in 589 after centuries of division since the fall of the Western Jin dynasty in 316. During his reign, the construction of the Grand Canal began.
