Why did the fisrt cities of mesopotamia need organized government?

Answer 1

Ancient cities needed organized government because they can't just lay around like pigs. If they were like pigs they wouldn't care if somebody from another place attack and/or kill people. Someone needed to organize things. They organized food for armies, people to build city walls, they trained armies and gave them weapons, clothing, and shelter.

Answer 2

Because humans need to be told what to do, cause if they aren't they will be like animals just lying around, after they have fulfilled their needs, and why should they be being lazy if the rulers can use them for something better.
