As food-producing economies spread and became more productive,
chiefdoms and eventually states developed in many parts of the world.A state is
a form of social and political organization that has a formal central
government and a division of society into classes.
The first states developed in Mesopotamia by 5500
chiefdoms were precursors to states with privileged and effective
leaders-chiefs but lacking the sharp class divisions that characterize
states.By 7000 in the Middle East there is evidence for an elite level
indicating a chiefdom or a state.
