Murong Jun
In 319 AD, Shi Le, the founder of the Later Zhao Kingdom, captured Ji from Duan Pidi, a Xianbei chieftain nominally loyal to the Jin Dynasty. In 349, Ran Min, an ethnic Han general seized control of this kingdom, which he renamed Ran Wei in 350. But before he could capture Ji, the city was taken by the Murong Xianbei, led by Prince Murong Jun who swept down from Manchuria. Murong Jun then defeated Ran Min and extinguished the Ran Wei. In 352, he declared himself emperor and made the city, the capital of the Former Yan Kingdom. Five years later, the Former Yan's capital was moved further south to Ye in southern Hebei.
