The ancient Sumerians of Mesopotamia, widely recognized as the oldest civilization in the world, emerged around 4000 BCE in what is now Iraq. By 2500 BCE, cities like Ur had developed complex social structures with defined roles for priests, merchants, artisans, and farmers. Located between the Tigris and Euphrates rivers, Mesopotamia—often called the cradle of civilization—was a hub of innovation. The Sumerians pioneered cuneiform writing, built the first known urban city-states, and made major advances in mathematics, astronomy, and governance. Simultaneously, Ancient Egypt, one of the first great river civilizations, began constructing its iconic pyramids in the 3rd millennium BCE, showcasing early mastery in architecture, engineering, and centralized monarchy along the Nile River.
