Inequality in ancient China took shape long before the first states emerged. A study of more than 2,300 burials shows how social ties shaped differences in wealth, health, and access to resources over thousands of years.
The research covers the Central Plain of China between 7000 and 1500 BCE. During this period, people held different positions within social networks, which affected their access to workers, food, scarce goods, and ritual objects. These differences formed early patterns of inequality before formal states took shape.
Researchers led by Dongdong Li examined burial records alongside data from human bones, animal remains, and chemical traces in ancient tissues. The records span nearly 6,000 years and offer clues about how people lived, ate, and interacted with others.

Burial goods helped the team assess differences in social standing. Human bones provided evidence of health, while dietary data showed differences in food access and variety. Together, these clues helped the researchers trace how social ties shaped people’s lives.
The results show a changing pattern of inequality over time. Differences in wealth and social standing didn’t grow at a steady rate. Farming growth and population size also failed to explain the main patterns.
Instead, a person’s place within a social network played a major role. Some people had better access to workers, useful goods, and objects with ritual or symbolic meaning. Others had fewer links to these resources. Such differences gave certain people an advantage long before states built formal systems of rule.
Access to scarce and prized goods helped create these unequal networks. Over time, changes in food production and other ways of meeting basic needs altered how people relied on one another. The spread of portable wealth also changed the balance between members of a community.
Portable wealth mattered because people could hold, move, and claim goods more easily. As control over these goods grew more concentrated, social ties also changed. Rising violent conflict added another source of change.
These shifts helped concentrate several forms of power. Some people gained greater control over rituals, political decisions, warfare, and technology. Their positions within social networks gave them access to resources and influence unavailable to others.
The study challenges the idea that deep inequality arose mainly from farming growth or the formation of states. Social relationships played a major role in shaping differences between people across prehistoric communities.
When early states emerged, they didn’t create these disparities from scratch. They strengthened existing differences by setting formal rules over resources, violence, and access through social networks. State institutions helped turn earlier advantages into more stable forms of control.
The findings place social relationships at the center of the long history of inequality. Differences in access to goods, labor, and influence took shape well before formal governments appeared. The rise of states then helped preserve these divisions, giving earlier social advantages a lasting structure.
