Origins of the Dai Clan

The origin of the “Dai” surname can be traced to several different sources:

  1. Using a posthumous title as a surname: This originated from the Zi surname and is descended from King Tang of the Shang Dynasty. According to the “Yuanhe Xing Zuan” and “Gujin Xingshi Shu Bianzheng,” in the early Zhou Dynasty, Duke Dan of Zhou granted the title of Duke Dai to Qi (of the Zi surname), the illegitimate son of King Zhou of Shang, and established the State of Song in the former capital of Shang (located south of present-day Shangqiu, Henan Province). The 11th ruler of the State of Song (reigning from 799–766 BC), whose name is unknown in history, was posthumously honored with the title “Dai Gong.” His descendants then adopted the surname “Dai.”

  2. Using the name of a state as a surname: This branch of the clan originated from the State of Dai, a ducal state during the Spring and Autumn period. This lineage also possibly stemmed from the Ji surname.

  3. From the Ji surname: There were individuals with the surname Dai within the state of Wei. For example, Dai Gong and Dai Bo from the state of Cao both had the Ji surname. Duke Huan of Lu had a son named Xi Shuya, who in turn had a son named Dai Bozi, also of the Ji surname. During the 15th year of Duke Xuan’s reign, there was a court official named Zhao Dai Gong, also of the Ji surname.

  4. The Yin clan changing to the Dai surname: According to the “Shu Pu,” some members of the Yin clan adopted the Dai surname after the fall of the Shang Dynasty. After King Wu of Zhou conquered Shang, many remnants of the Yin clan used the name of their former state as their surname. This branch of the Dai clan also originated in Henan.

  5. Changing surnames from other ethnic groups: For instance, members of the Manchu Dalchonga and Daijia tribes, as well as the Ewenki Tuakedong tribe, adopted the Dai surname. Other ethnic groups such as the Mongols, Hui, Yao, and Tujia also have people with the Dai surname.

  6. Chi You, the military leader: Chi You, the leader of the rebel forces, also had the surname Dai.

Progenitor of the Dai Clan

After Duke Dan of Zhou suppressed the rebellion led by Wu Geng, he granted the title of Duke Dai to Qi, the illegitimate son of King Zhou of Shang, and established the State of Song with its capital in Shangqiu. The 11th ruler of the State of Song (reigning from 799–766 BC) was posthumously honored with the title “Dai Gong.” His descendants adopted the surname “Dai.”
