Duke Jing of Qi

Duke Jing of Qi (Chinese: 齊景公; pinyin: Qí Jǐng Gōng; died 490 BC) was ruler of the State of Qi from 547 to 490 BC. Qi was a major power during the Spring and Autumn period of ancient China. His personal name was Lü Chujiu (呂杵臼), ancestral name Jiang (姜), and Duke Jing was his posthumous title.^[1][2] After the years of unrest as two powerful ministers, Cui Zhu and Qing Feng, sought to control the state of Qi, Duke Jing appointed Yan Ying as his prime minister, and Qi entered a period of relative peace and prosperity.
