Final answer:
Codification is the process of collecting and arranging laws into a written code, and King Hammurabi of the Babylonian Empire was the first to do this in present-day Iraq.
Step-by-step explanation:
Codification refers to the process of assembling and systematizing laws into a written code. In present-day Iraq, which was once part of the ancient Mesopotamian region, the first person to undertake such a monumental task of codification was King Hammurabi of the Babylonian Empire. Hammurabi's Code, inscribed on a stone stele and clay tablets in the cuneiform script, included laws that covered a wide range of issues, from inheritance to crime, and became a defining feature of his reign, influencing the legal systems of many civilizations that followed.
