沮渠蒙遜
In 410, Tufa Rutan and his brother Tufa Juyan (禿髮俱延) launched successive attacks on Northern Liang, and Juqu Mengxun was not only able to repel them, but then proceeded to siege Guzang (where Tufa Rutan had moved his capital after receiving it as a bestowmen from Yao Xing in 406). The people of Guzang, because Tufa Rutan had previously carried out massive executions after a failed rebellion, collapsed in fear, and more than 10,000 households surrendered to Northern Liang. Tufa Rutan, apprehensive of both Juqu Mengxun and a rebellion by Zhequ Qizhen (折屈奇鎮) in the south, made peace with Juqu Mengxun and moved his capital back south to Ledu (樂都, in modern Haidong Prefecture, Qinghai). As soon as he left Guzang, however, Hou Chen (侯諶) and Jiao Lang (焦朗) seized control of Guzang and nominally submitted to Juqu Mengxun, although they held Guzang themselves. In fall 410, Juqu Mengxun attacked Western Liang and defeated Li Gao's heir apparent Li Xin and captured the Western Liang general Zhu Yuanhu (朱元虎), and he subsequently made peace with Li Gao when Li Gao ransomed Zhu with silver and gold.
