Murong Jun (Chinese: 慕容儁; 319 – 23 February 360), Xianbei name Helaiba (賀賴跋), courtesy name Xuanying (宣英), also known by his posthumous name as the Emperor Jingzhao of Former Yan (前燕景昭帝), was the second and penultimate ruler of the Former Yan dynasty of China. He initially held the Eastern Jin-created title of Prince of Yan, but later claimed the title of emperor in 353. During his reign, the state expanded from possessing merely modern-day 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. The Book of Jin described Murong Jun as being approximately 2 metres (6.6 ft) tall and having an imposing look.

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 the Jin retroactively acknowledged that title in 341.
Historical accounts indicate that Murong Huang also considered Murong Jun's younger brother Murong Ba as the heir apparent, being impressed with Murong Ba's intelligence, but was dissuaded from it by his officials; those sources also attribute this as the reason why Murong Jun was jealous and apprehensive of Murong Ba. If this were true, it did not stop Murong Jun from granting his brother substantial authority during his reign.
The first historical mention of his being involved in leading the army was in 344, when he, along with his uncle Murong Ping, was commissioned to lead an army against Dai, but as the Dai prince Tuoba Shiyiqian refused to engage his army, no significant battle occurred.
In 346, Murong Huang commissioned him to command an army against Buyeo (Fuyu (夫餘) in Chinese), although the actual command appeared to be held by his brother Murong Ke. The army successfully in capturing the capital of Buyeo and its king Hyeon of Buyeo (玄王).
In 348, Murong Huang died. Murong Jun succeeded him as the Prince of Yan.
Prince of Yan
In 349, following the death of rival Later Zhao's emperor Shi Hu, Later Zhao fell into destructive wars with Shi Hu's sons and his adoptive grandson Shi Min (who later changed his family name back to his father's original "Ran"). Under the suggestion of Murong Ba (whom he had renamed Murong Chui by this point), Murong Jun prepared for expansion into Later Zhao's territory. He commissioned Murong Ke, Murong Ping, Yang Wu, and Murong Chui as major generals, preparing for a major attack against Later Zhao's border region.
In the spring of 350, Murong Jun launched the attack, and they quickly captured the important city of Jicheng (薊城, in modern Beijing). Murong Jun then moved the capital from Longcheng (龍城, in modern Jinzhou, Liaoning) to Jicheng. In short order, the entire Youzhou (幽州, modern Beijing, Tianjin, and northern Hebei) came under Former Yan's control. He then continued to march south, but temporarily halted his advances after nearly being defeated by the Later Zhao general Lubo Zao (鹿勃早).
Murong Jun resumed his campaign in the winter of 350, as Ran Min, who had by now established the new state of Ran Wei, was battling Later Zhao's remnants under Shi Zhi. He quickly captured a number of commanderies in Ji Province (冀州, modern central Hebei), approaching Shi Zhi's provisional capital Xiangguo (襄國, in modern Xintai, Hebei). Shi Zhi, under attack by Ran Min, sought Murong Jun's assistance in early 351, offering to surrender to Murong Jun the imperial seals (which he did not have). Murong Jun sent his general Yue Wan to join Shi Zhi and his general Yao Xiang, and their joint forces dealt Ran Min a major defeat, forcing Ran Min to give up on sieging Xiangguo for the time being, although soon thereafter Ran Min persuaded Shi Zhi's general Liu Xian (劉顯) to kill Shi Zhi, ending Later Zhao.
In the summer of 352, Murong Jun's and Ran Min's forces engaged in a major battle. Murong Ke, in command of Murong Jun's primary forces, tricked Ran Min's infantry into entering the plains, then dealt him a major defeat with attacks by cavalry forces. During the heat of the battle, Ran Min's horse was killed; he fell and the Murong troops captured him. When Ran was taken to Murong Jun, the latter rebuked him: "How could a lowly knave like you have the audacity to be a Pretender to the Throne?" (汝奴仆下才,何得妄称帝) However Ran Min, an ethnic Han, accused Murong Jun of being "an over-ambitious barbarian Pretender" (尔曹夷狄禽兽之类犹称帝) in turn. Enraged, Murong had Ran Min whipped 300 times, exiled and later beheaded; although he soon became apprehensive about the possibilities of Ran's vengeful spirit causing a draught, and eventually Ran was buried with honours.
Emperor
On 6 April 353, Murong Jun made his wife Princess Kezuhun empress and his heir apparent Murong Ye (慕容瞱) crown prince. In 354, Murong Jun made many of his uncles, brothers, and sons princes.
In 355, angered that his cousin Duan Kan (段龕), who was in control of modern Shandong and nominally a Jin vassal (as Duke of Qi), wrote a letter to him denouncing him for claiming an imperial title, Murong Jun sent Murong Ke and Yang Wu against him. In 356, despite the heavy fortifications that Duan's capital Guanggu (廣固, in modern Qingzhou, Shandong) had, Murong Ke sieged it, and after Duan's food supplies ran out, he was forced to surrender. Murong Jun initially spared Duan, but for unknown reasons, he executed Duan in 357.
Also in 356, Murong Jun's crown prince Murong Ye died, and in 357, Murong Jun made his younger son Murong Wei crown prince.
Later in 357, Murong Jun moved the capital from Jicheng to Ye.
In 358, Murong Jun began large scale conscription—ordering each family to send its service-eligible men into the army except for one per household—preparing to attack Former Qin and Jin. After a petition by Liu Gui (劉貴), he scaled back the conscription plan, ordering that for every five service-eligible men of the household, three enter the army.
Later in 358, the grudges between Murong Jun and Murong Chui flared up again. Murong Chui's wife Princess Duan, because her clan was an honored one—being previously on equal standing as the Murongs, with the title of Duke of Liaoxi—was not respectful of Murong Jun's wife Empress Kezuhun. The eunuch Nie Hao (涅浩), believing it to be the emperor and empress' wishes, falsely accused Princess Duan and Murong Chui's assistant Gao Bi (高弼) of witchcraft, with intent to drag Murong Chui into the case. However, despite torture, Princess Duan and Gao refused to admit, and Murong Chui avoided becoming entangled, although Princess Duan still died in prison. Murong Chui was effectively exiled as the governor of the remote Ping Province (平州, modern eastern Liaoning).
In 359, Jin forces under Zhuge You (諸葛攸) and Xie Wan (謝萬) attacked Former Yan, but were defeated by Former Yan forces. This victory allowed Former Yan to gradually take over the modern Henan region, south of the Yellow River.
