The History of the Peloponnesian War
Page: 112"The origin of our quarrel was this. We settled Plataea some time after the rest of Boeotia, together with other places out of which we had driven the mixed population. The Plataeans not choosing to recognize our supremacy, as had been first arranged, but separating themselves from the rest of the Boeotians, and proving traitors to their nationality, we used compulsion; upon which they went over to the Athenians, and with them did as much harm, for which we retaliated.
"Next, when the barbarian invaded Hellas, they say that they were the only Boeotians who did not Medize; and this is where they most glorify themselves and abuse us. We say that if they did not Medize, it was because the Athenians did not do so either; just as afterwards when the Athenians attacked the Hellenes they, the Plataeans, were again the only Boeotians who Atticized. And yet consider the forms of our respective governments when we so acted. Our city at that juncture had neither an oligarchical constitution in which all the nobles enjoyed equal rights, nor a democracy, but that which is most opposed to law and good government and nearest a tyranny—the rule of a close cabal. These, hoping to strengthen their individual power by the success of the Mede, kept down by force the people, and brought him into the town. The city as a whole was not its own mistress when it so acted, and ought not to be reproached for the errors that it committed while deprived of its constitution. Examine only how we acted after the departure of the Mede and the recovery of the constitution; when the Athenians attacked the rest of Hellas and endeavoured to subjugate our country, of the greater part of which faction had already made them masters. Did not we fight and conquer at Coronea and liberate Boeotia, and do we not now actively contribute to the liberation of the rest, providing horses to the cause and a force unequalled by that of any other state in the confederacy?
"Let this suffice to excuse us for our Medism. We will now endeavour to show that you have injured the Hellenes more than we, and are more deserving of condign punishment. It was in defence against us, say you, that you became allies and citizens of Athens. If so, you ought only to have called in the Athenians against us, instead of joining them in attacking others: it was open to you to do this if you ever felt that they were leading you where you did not wish to follow, as Lacedaemon was already your ally against the Mede, as you so much insist; and this was surely sufficient to keep us off, and above all to allow you to deliberate in security. Nevertheless, of your own choice and without compulsion you chose to throw your lot in with Athens. And you say that it had been base for you to betray your benefactors; but it was surely far baser and more iniquitous to sacrifice the whole body of the Hellenes, your fellow confederates, who were liberating Hellas, than the Athenians only, who were enslaving it. The return that you made them was therefore neither equal nor honourable, since you called them in, as you say, because you were being oppressed yourselves, and then became their accomplices in oppressing others; although baseness rather consists in not returning like for like than in not returning what is justly due but must be unjustly paid.
