Key passages

  • “Among the confederacies of antiquity, the most considerable was that of the Grecian republics, associated under the Amphictyonic council.”

    The most notable ancient confederation was the Greek league known as the Amphictyonic council.

    Madison introduces the first historical example to draw parallels with the American Confederation.

  • “Had Greece, says a judicious observer on her fate, been united by a stricter confederation, and persevered in her union, she would never have worn the chains of Macedon; and might have proved a barrier to the vast projects of Rome.”

    A wise commentator noted that if Greece had formed a tighter union and maintained it, she would have avoided conquest by Macedon and could have resisted Rome.

    Madison emphasizes the lesson that a stronger union prevents foreign subjugation.

  • “The Achaeans were cut to pieces, and Achaia loaded with chains, under which it is groaning at this hour.”

    The Achaean league was destroyed, and Greece remains enslaved under Roman rule.

    Madison concludes the historical account with a stark warning about the fate of disunited states.
