Ineed ! how did the social classes in athens and sparta compare to one another?

These city-states were very different. Sparta was traditionally the great land power of the Greek world and controlled many neighboring territories whose populations were tied to the land as slaves. Athens' power was based upon its command of the sea, and though it was officially only head of a naval alliance (the Delian League), in practice this amounted to an empire in all but name.

They both have strong millitary forces The females were both taken into school instead of war and The boys were all entered into the millitary

it affected it because the kingdoms (with trade) slowly got richer and richer.
