Wuzhi (Qi)

Lü Wuzhi (Chinese: 呂無知; pinyin: Lǚ Wúzhī), also known as "Wuzhi, Grandson of Duke" (Chinese: 公孫無知) and "Wuzhi, Marquess of Qi" (Chinese: 齊侯無知), was ruler of the Qi state for a few months in early 685 BC.

Yi Zhongnian died in 699 BC, but Wuzhi's uncle Duke Xi loved him and gave him the same treatment as his son, Crown Prince Zhu'er.

When the duke was recovering in his palace, Wuzhi killed him with the help of generals Lian Cheng (連稱) and Guan Zhifu (管至父), who had been mistreated by Duke Xiang.

[1][2] Wuzhi usurped the Qi throne after murdering Duke Xiang, but was killed by minister Yong Lin (雍廩) just a few months later in spring 685 BC.

After a brief struggle between Duke Xiang's two younger brothers Prince Jiu and Prince Xiaobai, Xiaobai would prevail and ascend the throne, posthumously known as Duke Huan of Qi.
