How did the bronze age cause a division in social classes?

The Bronze Age, characterized by the development of Metallurgy and advanced agricultural practices, led to increased production and trade, which created surplus wealth. This surplus enabled certain individuals or groups to accumulate resources, leading to the emergence of distinct social classes, including elites, artisans, and laborers. As societies became more complex, roles became specialized, and power dynamics shifted, with ruling classes exerting control over resources and labor, further entrenching social divisions. Additionally, the rise of urban centers facilitated the stratification of society based on wealth, status, and occupation.
