It appears that the cities had all the same laws and customs, the same weights and measures, and the same money. But how far this effect proceeded from the authority of the federal council is left in uncertainty. It is said only that the cities were in a manner compelled to receive the same laws and usages. When Lacedaemon was brought into the league by Philopoemen, it was attended with an abolition of the institutions and laws of Lycurgus, and an adoption of those of the Achaeans. The Amphictyonic confederacy, of which she had been a member, left her in the full exercise of her government and her legislation. This circumstance alone proves a very material difference in the genius of the two systems.
It is much to be regretted that such imperfect monuments remain of this curious political fabric. Could its interior structure and regular operation be ascertained, it is probable that more light would be thrown by it on the science of federal government, than by any of the like experiments with which we are acquainted.
One important fact seems to be witnessed by all the historians who take notice of Achaean affairs. It is, that as well after the renovation of the league by Aratus, as before its dissolution by the arts of Macedon, there was infinitely more of moderation and justice in the administration of its government, and less of violence and sedition in the people, than were to be found in any of the cities exercising SINGLY all the prerogatives of sovereignty. The Abbe Mably, in his observations on Greece, says that the popular government, which was so tempestuous elsewhere, caused no disorders in the members of the Achaean republic, BECAUSE IT WAS THERE TEMPERED BY THE GENERAL AUTHORITY AND LAWS OF THE CONFEDERACY.
We are not to conclude too hastily, however, that faction did not, in a certain degree, agitate the particular cities; much less that a due subordination and harmony reigned in the general system. The contrary is sufficiently displayed in the vicissitudes and fate of the republic.
