What was the primary cause of the rise in social inequality in agrarian societies?

The primary cause of the rise in social inequality in agrarian societies was the control of land and resources. In these societies, land was the main source of wealth and power, and those who owned large amounts of land could produce more food and generate more income. As a result, landowners often became very wealthy, while those who worked the land, like farmers and laborers, remained poor. For example, if one family owned a vast field and hired others to work it, they could accumulate wealth over time, while the workers struggled to make ends meet. This unequal distribution of land and resources created a clear divide between the rich and the poor, leading to social inequality.
