The only ancient Greek history of the Peloponnesian war that I know of yet. Athens and Sparta had each developed a sphere of influence - officially an alliance, but in practice more like an empire - until they had practically divided all Greece between them. So when they fought, all Greece fought, and all Greece was devastated. Though Thucydides was Athenian, the history is a little more sympathetic to the Spartans, who claimed to be liberating Greece from Athenian tyranny. But usually it exposes both sides' idealistic proclamations and calls for justice as covers for calculating, self-interested imperialism. The cynicism is more fatalistic than judgmental. The syntax is convoluted and a lot of the vocabulary is unfamiliar to me, so I didn't understand it that well. Since I was reading in Greek, and there are a lot of other things I want to read in Greek soon, I only finished books 1-4 out of nine.
