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.
Whilst the Amphictyonic confederacy remained, that of the Achaeans, which comprehended the less important cities only, made little figure on the theatre of Greece. When the former became a victim to Macedon, the latter was spared by the policy of Philip and Alexander. Under the successors of these princes, however, a different policy prevailed. The arts of division were practiced among the Achaeans. Each city was seduced into a separate interest; the union was dissolved. Some of the cities fell under the tyranny of Macedonian garrisons; others under that of usurpers springing out of their own confusions. Shame and oppression erelong awaken their love of liberty. A few cities reunited. Their example was followed by others, as opportunities were found of cutting off their tyrants. The league soon embraced almost the whole Peloponnesus. Macedon saw its progress; but was hindered by internal dissensions from stopping it. All Greece caught the enthusiasm and seemed ready to unite in one confederacy, when the jealousy and envy in Sparta and Athens, of the rising glory of the Achaeans, threw a fatal damp on the enterprise. The dread of the Macedonian power induced the league to court the alliance of the Kings of Egypt and Syria, who, as successors of Alexander, were rivals of the king of Macedon.
This policy was defeated by Cleomenes, king of Sparta, who was led by his ambition to make an unprovoked attack on his neighbors, the Achaeans, and who, as an enemy to Macedon, had interest enough with the Egyptian and Syrian princes to effect a breach of their engagements with the league.
The Achaeans were now reduced to the dilemma of submitting to Cleomenes, or of supplicating the aid of Macedon, its former oppressor. The latter expedient was adopted. The contests of the Greeks always afforded a pleasing opportunity to that powerful neighbor of intermeddling in their affairs. A Macedonian army quickly appeared. Cleomenes was vanquished. The Achaeans soon experienced, as often happens, that a victorious and powerful ally is but another name for a master. All that their most abject compliances could obtain from him was a toleration of the exercise of their laws. Philip, who was now on the throne of Macedon, soon provoked by his tyrannies, fresh combinations among the Greeks. The Achaeans, though weakened by internal dissensions and by the revolt of Messene, one of its members, being joined by the Aetolians and Athenians, erected the standard of opposition. Finding themselves, though thus supported, unequal to the undertaking, they once more had recourse to the dangerous expedient of introducing the succor of foreign arms. The Romans, to whom the invitation was made, eagerly embraced it. Philip was conquered; Macedon subdued. A new crisis ensued to the league. Dissensions broke out among its members. These the Romans fostered.
