Mesopotamian kings were rulers of ancient civilizations located between the Tigris and Euphrates rivers, primarily in modern-day Iraq. They held significant power and were often seen as representatives of the gods on Earth. Kings like Sargon of Akkad and Hammurabi established laws and built monumental structures, contributing to the development of society. These kings were responsible for maintaining order, collecting taxes, and leading armies. They often claimed divine right to rule, which helped legitimize their authority. The Code of Hammurabi, one of the earliest written legal codes, exemplifies how kings influenced governance and justice in Mesopotamia.
