Leave being granted, the Thebans spoke as follows: "We should never have asked to make this speech if the Plataeans on their side had contented themselves with shortly answering the question, and had not turned round and made charges against us, coupled with a long defence of themselves upon matters outside the present inquiry and not even the subject of accusation, and with praise of what no one finds fault with.

However, since they have done so, we must answer their charges and refute their self-praise, in order that neither our bad name nor their good may help them, but that you may hear the real truth on both points, and so decide.
"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.
