Duan Meng was a Hu person. In the dingyou year, the first year of the Long'an reign era of Emperor An of the Eastern Jin, he occupied Zhangye, named [his state] Northern Liang, and took the title King of Hexi; the era was named Shenxi. In the jihai year, he changed the reign era to Tianxi. In the xinchou year, King Wuxuan, Juqu Mengxun, ascended the throne and changed the reign era to Yong'an. In the renzi year, he moved the capital to Guzang and changed the era name to Yuanshi. In the wuchen year, he changed the reign era to Chengxuan. In the gengwu year, Mengxun sent tribute to the Northern Wei. In the xinwei year, he changed the reign era to Yihe. In the renshen year, the Northern Wei sent General Pacifying the West Li Shun as an envoy to Liang; upon his return, the Wei ruler questioned him about Liang affairs. Shun said: 'Mengxun has passed through hardship and has a rough grasp of opportunism. Yet propriety is the arising of virtue, and respect is the foundation of one's person. Mengxun lacks propriety and is without respect; as your servant sees it, he will not last many years.' In the guiyou year, Mengxun died. His son Mujian, the Grand Protector of Dunhuang, succeeded to the throne of the King of Hexi and changed the reign era to Chenghe. Although Mujian outwardly observed the etiquette of a subject, inwardly he was perverse and rebellious. In the third month of the jimao year, the Wei ruler campaigned against Liang. In the sixth month, the Wei ruler reached Guzang. In the ninth month, Wannian, the son of Mujian's elder brother, surrendered to Wei with his command. The city of Guzang collapsed. Mujian, with his civil and military officials numbering five thousand, surrendered with hands tied behind their backs. The Wei ruler untied their bonds and treated them with courtesy. The three rulers lasted a total of forty-three years. Zhangye is now Ganzhou Route. Guzang is Liangzhou. Dunhuang is Liangzhou Route. All belong to Gansu Province, within the territory of Yongzhou (from the Illustrated Treatises).
