How is one civilization ordered people in order of importance and explain their roles?

Civilizations often structured their societies in hierarchical systems, with a clear ranking of individuals based on factors like wealth, power, and occupation. At the top were rulers or monarchs, who held political authority and made key decisions. Below them were nobles or aristocrats, who managed land and resources, followed by priests or religious leaders responsible for spiritual guidance. The lower tiers typically included merchants, artisans, and farmers, whose roles focused on trade, craftsmanship, and agriculture, providing essential goods and services for the society's survival.
