Of Asia and Egypt I need not speak before the time at which my history commences. The previous history of these countries has been written by a number of historians already, and is known to all the world; nor in our days has any change specially remarkable or unprecedented occurred to them demanding a reference to their past. But in regard to the Achaean league, and the royal family of Macedonia, it will be in harmony with my design to go somewhat farther back: for the latter has become entirely extinct; while the Achaeans, as I have stated before, have in our time made extraordinary progress in material prosperity and internal unity. For though many statesmen had tried in past times to induce the Peloponnesians to join in a league for the common interests of all, and had always failed, because every one was working to secure his own power rather than the freedom of the whole; yet in our day this policy has made such progress, and been carried out with such completeness, that not only is there in the Peloponnese a community of interests such as exists between allies or friends, but an absolute identity of laws, weights, measures, and currency.[155] All the States have the same magistrates, senate, and judges. Nor is there any difference between the entire Peloponnese and a single city, except in the fact that its inhabitants are not included within the same wall; in other respects, both as a whole and in their individual cities, there is a nearly absolute assimilation of institutions.
