So again, it is to be recollected that Athenian private citizens, not officially employed, were spread over the whole range of the empire as kleruchs, proprietors, or traders; of course, therefore, disputes would arise between them and the natives of the subject cities, as well as among these latter themselves, in cases where both parties did not belong to the same city. Now in such cases the Spartan imperial authority was so exercised as to afford little or no remedy, since the action of the harmost or the dekadarchy was confined to one separate city; while the Athenian dikasteries, with universal competence and public trial, afforded the only redress which the contingency admitted. If a Thasian citizen believed himself aggrieved by the historian Thucydidês, either as commander of the Athenian fleet off the station, or as proprietor of gold mines in Thrace, he had his remedy against the latter by accusation before the Athenian dikasteries, to which the most powerful Athenian was amenable not less than the meanest Thasian. To a citizen of any allied city, it might be an occasional hardship to be sued before the courts at Athens, but it was also often a valuable privilege to him to be able to sue before those courts others whom else he could not have reached. He had his share both of the benefit and of the hardship. Athens, if she robbed her subject-allies of their independence, at least gave them in exchange the advantage of a central and common judiciary authority; thus enabling each of them to enforce claims of justice against the rest, in a way which would not have been practicable, to the weaker at least, even in a state of general independence.
