Final answer:
The Mesopotamians made a significant contribution to the pursuit of justice by creating the first written law, known as Hammurabi's Code, which influenced later legal systems.
Step-by-step explanation:
The Mesopotamians were the first to give the world the first great contribution to man's continuing search for justice: written law, which was based on an awareness of the rights of an individual. Hammurabi's Code, written five centuries before the Mosaic Code, greatly influenced Jewish and Christian laws, and Islam developed its formal legal codes after the conquering of what is today Iraq. The Code of Hammurabi is a significant artifact that not only detailed laws for various aspects of daily life, such as business transactions and family affairs but also introduced concepts like the presumption of innocence and evidence-based judgments. It was a monumental work that predated biblical laws and fostered the development of legal systems in both the ancient and modern worlds.
