The surname Cai, as one of the oldest surnames in China, carries rich historical and cultural connotations. Exploring the origin and history of the surname Cai not only helps us understand the formation process of this surname, but also allows us to better appreciate the long historical inheritance of the Chinese nation. This article will focus on the origin of the surname Cai and the conferral of the title of "Duke of Cai" by King Wu of Zhou to his brother Shudu, and reveal the historical story behind the surname Cai.

I. Origin of the Surname Cai

The origin of the surname Cai can be traced back to the Western Zhou Dynasty. According to historical records, after King Wu of Zhou destroyed the Shang Dynasty and established the Zhou Dynasty, he divided the land among his vassals and granted his brother Shudu the title of "Duke of Cai" (located in the area of Shangcai County, Henan Province today). Shudu became the ruler of Cai and his descendants took the name of the state as their surname, hence the surname Cai. This is the earliest source of the surname Cai.

II. Historical Evolution of Cai State

As a vassal state during the Western Zhou Dynasty, Cai experienced many changes in its fortune over multiple dynasties. During the Spring and Autumn Period, Cai was once a powerful state, but gradually declined during the Warring States Period. In 447 BC, Cai was annexed by the State of Chu, and its territory and people were incorporated into Chu. The annihilation of Cai State had a certain impact on the inheritance of the surname Cai, but the Cai people did not disappear. Instead, they continued to multiply and thrive throughout history.

III. Inheritance and Development of the Surname Cai

Over time, the surname Cai gradually spread throughout the country. Especially in the late Eastern Han Dynasty, cultural figures such as Cai Yong and Cai Wenji emerged, making the surname Cai stand out in the cultural field.
