The notable civilization that developed the first known code of laws was the Sumerians, specifically through the Law Code of Ur-Nammu, which dates back to around 2100-2050 BCE. However, the more famous and widely recognized code is the Code of Hammurabi, established by the Babylonian king Hammurabi around 1754 BCE. This code consisted of 282 laws, covering various aspects of daily life, trade, family, and justice. Its principle of "an eye for an eye" emphasized retribution and social order. Both codes exemplified the early attempts at creating structured legal systems to govern society.
