The Persians .
Many.
Islam (muslims)

sparta,athens and other city states united against a common foe-the persians. were able to keep the persians from conquering the greeks.
a common enemy being the Persians in which they united armies to fight a common enemy
In Amazigh Language and Culture (berbers and moors)
They all attacked parts of the roman empire
All of those three groups were, at one time, enemies of the Roman Empire.
They formed an alliance because they wanted to rebel against the Persians. Athens had all the brains and Sparta had all the war like abilities. Athens needed someone that was good in war. Even though Athens had a strong army it was still too small to over ride the Persian Empire. The Persians were a common enemy for Athens and Sparta. They both had something in common; liking the Persians. So the more people Athens had in their army the more likely it is for Athens to win. In the end Athens does win the war against the Persians but there are many more wars the Athenians and the Persians have had against each other.
