 Social Classes (for ex: 2nd class...) 
In Mesopotamia, they have 3 social classes: 1st, 2nd, and 3rd. The kings, priests, and wealthy people
were in 1st class (the top). The 2nd class had merchants, fishermen, etc. They don't have wealthy houses, like the 1st class people have. Last but not least, the 3rd class. The 3rd class had slaves. The slaves are for to help and do work for the 1st and some 2nd class people. 

 King Hammurabi 
King Hammurabi ruled a place in Mesopotamia called Babylonia. He was a very tough king. He was one of the first kings to write laws for his people. But he was the first king to hang his rules/ laws up in every place in Babylonia, so if someone breaks the law, no one can complain or tell they never noticed or read the laws. These laws are called The Hammurabi Code. 

 The Hammurabi Code 
The Hammurabi code are laws written in stone. Scientists had found a stone of laws written by a priest that was told to write the laws that King Hammurabi said. one of the laws are "If you kill a father's son in the fire, then your son will be killed in the fire too." or "If you steal something during a fire, then you will chop off your hands." Most of these laws/ rules protect women and 3rd class people.
