The ancient civilization linked to the development of the first known laws is Mesopotamia, particularly through the Code of Hammurabi, established around 1754 BCE. Hammurabi, the sixth king of Babylon, created this codified set of laws inscribed on a stone stele, addressing various aspects of daily life, including trade, property, and family relations. The code is notable for its use of the principle of "an eye for an eye," highlighting early legal thought and the concept of justice. Hammurabi's Code laid foundational legal principles that influenced future legal systems and provided insights into the social and economic structures of ancient Mesopotamian civilization.
