Two years after his completion of the three orations, Isocrates wrote an oration for Archidamus, the prince of Sparta. Isocrates considered the settling of the Thebans colonists in Messene a violation of the Peace of Antalcidas. He was bothered most by the fact that this ordeal would not restore the true Messenians but rather the Helots, in turn making these slaves masters. Isocrates believed justice was most important, which secured the Spartan laws but he did not seem to recognize the rights of the Helots. Ten years later Isocrates wrote a letter to Archidamus, now the king of Sparta, urging him to reconcile the Greeks, stopping their wars with each other so that they could end the insolence of the Persians.
