Duke Zhuang succeeded his father Duke Cheng of Qi, who died in 795 BC, as ruler of Qi. He had a long reign during an era of upheaval in China. In 771 BC, the Quanrong tribes from the west attacked Haojing, capital of the Zhou dynasty, and killed King You of Zhou. Duke Xiang of the state of Qin sent his army to escort King You's son King Ping of Zhou to the new capital Luoyi, marking the beginning of the Eastern Zhou dynasty. As a reward for Qin's protection King Ping formally granted Duke Xiang of Qin a nobility rank and elevated Qin to the status of a vassal state on par with other major states such as Qi and Jin. Although Qi was little affected by the turmoil as it was located east of the Zhou territory, the state of Qin would from then on grow stronger and eventually conquer Qi in 221 BC and unite China under the Qin dynasty.[2]

Duke Zhuang reigned for 64 years and died in 731 BC. He was succeeded by his son, Duke Xi of Qi.[1][2]
