In the greater number of cities, he established an oligarchy of ten citizens, or a decarchy, composed of his own partisans; while he at the same time planted in each a Lacedæmonian harmost or governor, with a garrison, to uphold the new oligarchy. The decarchy of ten Lysandrian partisans, with the Lacedæmonian harmost to sustain them, became the general scheme of Hellenic government throughout the Ægean, from Eubœa to the Thracian coast towns, and from Miletus to Byzantium. Lysander sailed round in person with his victorious fleet to Byzantium and Chalcedon, to the cities of Lesbos, to Thasos, and other places--while he sent Eteonicus to Thrace for the purpose of thus recasting the governments everywhere. Not merely those cities which had hitherto been on the Athenian side, but also those which had acted as allies of Sparta, were subjected to the same intestine revolution and the same foreign constraint. Everywhere the new Lysandrian decarchy superseded the previous governments, whether oligarchical or democratical. In what spirit these new decarchies would govern, consisting as they did of picked oligarchical partisans distinguished for audacity and ambition--who, to all the unscrupulous lust of power which characterised Lysander himself, added a thirst for personal gain, from which he was exempt, and were now about to reimburse themselves for services already rendered to him--the general analogy of Grecian history would sufficiently teach us, though we are without special details. But in reference to this point, we have not merely general analogy to guide us; we have further the parallel case of the Thirty at Athens, the particulars of whose rule are well known and have already been alluded to.
