Herodotus' narrative analysis of historical events and social phenomena has some advantages. Regarding the Persian war, he condemned the Persian expedition to Greece, saying that Persia "should no longer covet any other land and should no longer enslave those who are not provocative at all." It is believed that Persia failed because its military composition is too complicated and it is difficult to fight on exterior lines. Athens won, because it practiced democracy, and everyone fought for freedom "wholeheartedly".

Herodotus admired Greece, praised Athens and yearned for the democratic politics of slave owners, but he did not completely deny Persia. What he opposed was the unjust behavior of Persians invading Greece and its monarchy. So sometimes he even described Persia as a heroic country, choosing and praising its culture.
