How did the Persian wars affect greek unity?

Answer 1

For the 50 years of the War 499-449 BCE, most of the normal fighting between Greek city-states was diverted to opposing Persian attempts to bring peace to the Eastern Mediterranean.

At the end of the War, Persia gave up and the city-states went back to their normal fighting between each other.

Answer 2

There was little Greek unity. The Greek world comprised several hundred independent city-states some of which from time to time joined several leagues, and even changed leagues as it suited them.

So there was no Greek unity. After some of the states joined together to repel the Persians, they then returned to fighting each other. Again, leagues appeared and dissolved.

Their unifying factor was quasi-religious - the Amphytionic League whic pontificated on religious and cultural matters, however this was eventually harnessed by proxies of Phillip II of Macedonia, a nom-member - as a control measure in Greek affairs.

Answer 3

It did not lead to Greek unification. Half the Greek states were on the side of Persia, and after the southern Greek city-states repelled the persian invasion, they went back to their usual activity to fighting each other, leading eventually to the disastrous Peloponnesian War which devastated Greece.

Answer 4

With the threat of takeover by Persia, the city-states united to repell it as none were capable of resisting by themselves. After peace was made when the invasion was repelled, the Greek city-states went back to fighting each other.

Answer 5

The Greek polis in mid and northern Greece were unified in joining Persia's attack in the southern Greek polis which unified in defeating the Persian force and its Greek polis allies.

Answer 6

For survival as independent city-states.
