Duke Kang of Qi
Ruler of the State of Qi from 404 to 386 BC

Duke Kang of Qi (Chinese: 齊康公; pinyin: Qí Kāng Gōng), personal name Lü Dai, was duke of the Qi state from 404 BC to 386 BC. He was the final Qi ruler from the Jiang clan. The throne of Qi was thereafter usurped by the Tian clan, thus ending the Jiang Qi (姜齊) dynasty and establishing the Tian Qi (田齊) dynasty.
Reign
Duke Kang succeeded his father, Duke Xuan of Qi, who died in 405 BC after 51 years of reign as titular ruler of Qi. Since Tian Heng killed Duke Xuan's uncle Duke Jian of Qi in 481 BC, the leaders of the Tian clan had been the de facto rulers of Qi.
Tian He was leader of the Tian clan during Duke Kang's reign. With the lobbying of Marquis Wu of Wei, in 386 BC King An of Zhou, the nominal ruler of all China, officially recognized Tian He as ruler of Qi, ending more than six centuries of rule by the House of Jiang. Tian He became the first de jure ruler of Qi from the House of Tian, and is posthumously known as Duke Tai of Tian Qi.

Why this record matters

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 9, 2026. The linked authority identifier is Q709741. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
