Muzhun Y

Muzhun's father was Muzhun Huan, who bore the title "Prince of Idus" (宜都 王) and was the son of the founder of the state, Early Yan Muzhun Huang .

In the year 370, Early Yan was destroyed by the Early Qin state , and most of the Syanbi were resettled in the internal Qin lands. In 384, the Syanbi rebelled, and Muzhun Chun proclaimed himself emperor of the state of Western Yan. In 385, he took the Qin capital of Chang'an . Despite the fact that the Syanbians wanted to return east to their native lands, Muzhun Chun decided to stay in Chang'an, not wanting to join Uncle Muzhun Chuy , who founded the state of Late Yan . He tried to persuade his people to follow his example, but did not find understanding. In the spring of 386, General Han Yan staged a palace coup, killed Muzhun Chun and seated General Duan Sui , who received the title "Prince Yan" (燕王), on the throne. However, a month later, Muzhun Heng and Muzhun Yong killed Duan Sui and enthroned Muzhun I.

After that, the people of Western Yan - about 400 thousand men and women - left Chang'an and moved east from Guanzhong to their native places. On the way, when they were on the lands of modern Weinan , Muzhun’s brother Heng Mujun Tao killed Mujun Yi, and Mujun Chun’s son Mujun Yao was enthroned.
