Explain how ancient Greece was destroyed by warfare.

The Persian king Darius first attacked Greece in 490 BC, but was defeated at the Battle of Marathon by a mainly Athenian force ... The Athenian Acropolis was destroyed by the Persians, but the Athenian response was to build the beautiful buildings whose ruins we can still see today.

Answer:In the ancient Greek world, warfare was seen as a necessary evil of the human condition. Whether it be small frontier skirmishes between neighbouring city-states, lengthy city-sieges, civil wars, or large-scale battles between multi-alliance blocks on land and sea, the vast rewards of war could outweigh the costs in material and lives.
