Ancient societies had several key traits: 1) They transitioned from hunter-gatherers to horticultural and pastoral societies that farmed crops and domesticated animals, requiring stable water, soil, locations, and environmental conditions. 2) They developed social hierarchies with nobility, priests, merchants, farmers, laborers, and slaves at the top and bottom. 3) Religion played an important spiritual role, and myths portrayed good triumphing over evil. Traits of ancient societies helped them survive and interact through trade between places like Egypt and Mesopotamia.
