Duke Ling of Jin, personal name Ji Yigao, was from 620 to 607 BC the duke of the Jin state. He ascended the throne with the support of his regent, Zhao Dun (Viscount Xuan of Zhao).[2]
In 607 BC, 14 years after ascending the throne, Duke Ling had reached adulthood and become increasingly despotic. He was known to have had his chef killed for not cooking his bear paws well. Zhao Dun, who enjoyed a reputation for integrity and incorruptibility, tried to stop him. Resentful of Zhao Dun's influence, Duke Ling tried to have Zhao Dun assassinated. Zhao Dun managed to escape, and on 19 August, his half-brother Zhao Chuan (趙穿) rebelled and killed Duke Ling.[3] Zhao Dun and Zhao Chuan then installed Duke Ling's uncle, Duke Cheng, on the throne of Jin.[2]
