Korean Confucianism
Under the succeeding Han Dynasty and Tang Dynasty, Confucian ideas gained even more widespread prominence. During the Song Dynasty, the scholar Zhu Xi (AD 1130–1200) added ideas from Taoism and Buddhism into Confucianism. In his life, Zhu Xi was largely ignored, but not long after his death his ideas became the new orthodox view of what Confucian texts actually meant. Modern historians view Zhu Xi as having created something rather different, and call his way of thinking Neo-Confucianism. Neo-Confucianism held sway in China, Japan, Korea and Vietnam until the 19th century.
Zhu Xuan
Zhu Xuan (朱瑄 or 朱宣) (d. 897) was a warlord late in the Chinese dynasty Tang Dynasty, who, from 882 to 897, controlled Tianping Circuit (天平, headquartered in modern Tai'an, Shandong) as its military governor ("Jiedushi"). He formed a power bloc with his cousin Zhu Jin, who ruled neighboring Taining Circuit (泰寧, headquartered in modern Jining, Shandong), and subsequently, they, along with their ally Shi Pu the military governor of Ganhua Circuit (感化, headquartered in modern Xuzhou, Jiangsu), engaged in a lengthy war with their former ally Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) that ravaged the countryside. By 897, all three had been defeated, and Zhu Xuan was captured and executed by Zhu Quanzhong.
