What can we learn about the life of the Babylonians from the laws of Hammurabi?

From his laws we learn that even then Babylonian society was quite developed. There, at a high level, there were various public institutions, such as the courts, law enforcement agencies, etc. There was also some protection for the rights of the Babylonians themselves. So it was forbidden by law to sell the Babylonians into slavery to another country. If a Babylonian slave was bought in another country, then he should be immediately released. At the same time, the laws were rather harsh in relation to crimes.
