Greece was always split in half because of this rivalry.
Split in half ???
I would say split in tons of independant cities, fighting for their own interest & power.
Sadly people are led to believe that the Spartans were glorious, honourable and mighty warriors
Hmmm, the Spartans were zealots, fanatic warriors and raised in violence.
But yes i'm sorry, they were very good in the hoplite melee fight-style.
[...]but the truth is that the Athenians were always above the Spartans at everything, military, trade, culture, wealth, and that always annoyed the Spartans, made them envy the Athenians.
Where the spartans were excellent
in only one thing : Hoplite melee fight,
The Athenians developped science, culture, philosophy & many technologies.
However, the Athenians who created their fresh democracy after kicking the last "tyran", had no dedicated army. (Time of the battle of Marathon)
The "Athenians-hoplite-civilian" equiped & bought their stuff by themself. They didn't grow in a life of violence with a permanent training. (as Sparta)
When Darius, invaded Thracia, Makedon and pushed to Greece, Athens sent diplomats in order to gather independant cities. Plataea accepted fast and sent soldiers.
Sparta accepted as well but they explained that they wont come till the end of their religious event. (which means too late to save Athens' city)
Miltiades (who was leading the "greek-league") proved to other greek states that the Athenians were also great warriors in ground battlefield with the great victory at Marathon.
Around 200 greeks died for 6.000 persians.
(Pretty nice KD ) Sparta arrived 5 days after the victory of Marathon. And went back at home without glory.
Themistocles (who fought in Marathon as a strategoï for Athens) understood that the Persians will come back again.
He used the threat of their pirat greek neighbor to start building an important fleet. (which will save them when Xerses' fleet pushed into Greece)
At this point, Athens became a powerfull trading & naval city over Greece.
Apart from the glorious hold at the Hotgates, Spartans have done nothing else that actually justifies their huge reputation.
Yes, when Xerses surrounded the "greek-coaliltion" at the battle of the thermophiles, Sparta succesfully used this defeat as an act of sacrifice from their soldiers.
They always sided with the enemy for gold and weapons, they would always cause problems at time of peace for no apparent reason.
As i just wrote it above, it's not always the truth.
But when it was greek-wars, yes they rarely sided with Athens.
If they could make Athens weaker they would try it.
Do yourself a favour and dont believe the crap that you read about spartans (no walls at sparta, the "If" reply to Phillip) all are lies.
Yes, occidentals are still using propaganda, even if it's much more incidious, less retarded than the East, etc... But yes, we still have our own kind of propaganda, and USA is very good at it.
