Why was Sparta more warlike Athens was primarily focused on learning?

Answer 1

Sparta's very society was based on a war culture. Infants who were ill or born with birth defects were allowed to die. Only the strong survived. At nine years old, boys became wards of the state, taken from their parents, and trained as soldiers. They considered themselves in a perpetual state of war against the Helots, their slave population. Some believe that this is because the Spartans were interlopers who invaded the Greek territories and settled there. By contrast, Athens was a democracy which existed by maritime trade. That opened them up to exposure to and acceptance of other cultures and views.
