Step-by-step explanation:
The oldest written law code was the Ur-Nammu law code. This law code was written around 300 years before the law code of Hammurabi. The Ur-Nammu law is the law of the Eshunna town, of king Lipit-Ishtar of Isin.
On the other hand, the Hammurabi code is a collection of 282 regulations, established by Hammurabi, the king of Babylon in 1750 BC. He was the one who wanted his people to know about his rules and laws thus he ordered his officers to display his laws publicly.
