From The Federalist Papers
Very different, nevertheless, was the experiment from the theory. The powers, like those of the present Congress, were administered by deputies appointed wholly by the cities in their political capacities; and exercised over them in the same capacities. Hence the weakness, the disorders, and finally the destruction of the confederacy. The more powerful members, instead of being kept in awe and subordination, tyrannized successively over all the rest. Athens, as we learn from Demosthenes, was the arbiter of Greece seventy-three years. The Lacedaemonians next governed it twenty-nine years; at a subsequent period, after the battle Leuctra, the Thebans had their turn of domination.
It happened but too often, according to Plutarch, that the deputies of the strongest cities awed and corrupted those of the weaker; and that judgment went in favor of the most powerful party.
Even in the midst of defensive and dangerous wars with Persia and Macedon, the members never acted in concert, and were, more or fewer of them, eternally the dupes or the hirelings of the common enemy. The intervals of foreign war were filled up by domestic vicissitudes, convulsions, and carnage.
After the conclusion of the war with Xerxes, it appears that the Lacedaemonians required that a number of the cities should be turned out of the confederacy for the unfaithful part they had acted. The Athenians, finding that the Lacedaemonians would lose fewer partisans by such a measure than themselves, and would become masters of the public deliberations, vigorously opposed and defeated the attempt. This piece of history proves at once the inefficiency of the union, the ambition and jealousy of its most powerful members, and the dependent and degraded condition of the rest. The smaller members, though entitled by the theory of their system to revolve in equal pride and majesty around the common center, had become, in fact, satellites of the orbs of primary magnitude.
