Sparta
In Ancient Greece, Sparta was a city-state with a very strong army and a government that was well led.  Sparta was known as one of the strongest city-states in Greece.  Only the strongest survived in Sparta, male or female.  The Spartans killed weak children.  If they believed that a baby was too weak, they left it out to die of exposure beside a slope on Mount Taygetus.  This place was called the Apothetae, which meant 'the place of rejection'.
