Why did Sparta and Athens become comrades in arms in the face of the challenge from Persia?

The most essential reason why Sparta and Athens became allies is because of the entanglement of interests. In fact, the relationship between Sparta and Athens and Persia was not a simple relationship, in the early days, Sparta sought help from Persia and wanted to become an ally with Persia, but in the later period, he gave up his pursuit of Persia and chose Athens insteadBut no matter which country it is, Sparta is looking for the best solution in the environmental situation.

Sparta itself is a land country, although relatively powerful, but mostly hand-to-hand combatAnd his ability to fight at sea was very weak, and this weakness put him in a weak position in the struggle at sea, unable to fight Persia on his own.

Secondly, although it has a lot of disagreement with Athens, it is fundamentalSparta also had a great dislike for PersiaBecause Sparta wanted to get help from Persia before, Persia said that it needed Sparta to recognize its suzerainty, and Sparta felt that he should be the liberator, and recognizing the suzerainty of Persia was undoubtedly a resounding slap in the face to himself.

The ancestors of Sparta once led the Greeks and drove the Persians out of Greece and even the Aegean region, but promised Persia, and the glory that his ancestors had exchanged for flesh and blood became nothing.

This is a shame for the Spartans, who regard glory as everything, and the Spartans are resistant to the Persians, especially when the Persians send troops, they can only turn enemies into friends with Athens, and first solve the biggest enemy in front of themIn order to defend themselves against the mighty Persia, the two countries chose to stand together, become allies, and expand each other's power.

The community of interests will prosper and lose both, so when Persia attacks, Sanda will definitely form an alliance with Athens to jointly protect interests.

The most essential reason why Sparta and Athens became comrades-in-arms in seconds is because of the entanglement of interests, no matter which country it is, what Sparta pursues is the optimal solution under the environmental situation.

The Persian Empire was too powerful. Both Sparta and Athens saw Persia's ambition to devour the world, so they soon united against Persia.

For the sake of their own interests, to protect themselves, in order to be able to defeat Persia, it is what makes Sparta and Athens allies, and it is also driven by the situation.

When countries go to war or become allies, the fundamental reason is that there is a conflict of interest or a convergence of interests, and the relationship changes.

The enemy of your enemy is your friend, there is no permanent enemy, only eternal interests, in this case of course the alliance is reliable.

In the face of the challenge from Persia, will Sparta and Athens become allies, or because of interests?

The enemy of the enemy is the friend, and in the face of a more powerful enemy, Sparta and Athens will definitely form an alliance.
