What type of Government ruled Ancient Mesopotamia? Please help!!!

 Mesopotamia was ruled by kings. The kings only ruled a single city though, rather than the entire civilization. For example, the city of Babylon was ruled by King Hammurabi. Each king and city designed the rules and systems that they thought would be most beneficial for their people.

Explanation: I just learned all about Mesopotamia.

the factors that the economies of the muslim empires prosper were:

1- land trade routes-located between three continents  

2- sea trade routes

trade contributed to the spread of muslim empires, and with that islamic culture led to a growing feeling of internationalism resulted in the transfer of technology, science, and other cultural forms.

okay what's the question?
