Duke Li of Chen (Chinese: 陳厲公; pinyin: Chén Lì Gōng; reigned 706 BC – died 700 BC), personal name Gui Yue, was a duke of the Chen state.
He was believed to have become demented and went missing in the first month of 707 BC, before his body was found sixteen days later.
The uncertainty threw the state into turmoil, and Duke Huan's younger brother Chen Tuo took the opportunity to murder Duke Li's elder brother Crown Prince Mian and usurp the throne.
[1] Duke Li was the father of Chen Wan (陳完), who later fled to the Jiang Qi state in 672 BC.
The Tian (田) clan descended from Chen Wan grew increasingly powerful over the centuries and eventually usurped the Jiang Qi throne and founded the Tian Qi state.
