Murong Jun
Murong Jun (Chinese: 慕容儁; 319–360), courtesy name Xuanying (宣英), formally Emperor Jingzhao of (Former) Yan ((前)燕景昭帝), was an emperor of Former Yan. He was the state's second ruler, but after first using the Jin Dynasty (265-420)-created title of Prince of Yan, was the first to use imperial title, as during his reign the state expanded from possessing merely modern Liaoning and parts of Hebei to nearly all of the territory north of the Yellow River and some substantial holdings south of the Yellow River.
Early career
Murong Jun was born in 319, while his father Murong Huang was still the heir apparent to his grandfather Murong Hui, the Jin-created Duke of Liaodong. In his youth, he was considered to be learned in both literary and military matters. Sometime after his father succeeded his grandfather in 333, he was made the heir apparent, a status that he retained after his father claimed the title Prince of Yan in 337 and after Jin retroactively acknowledged that title in 341.
