XVIII: The Same Subject Continued (The Insufficiency of the Present Confederation to Preserve the Union) explained

What happens

Madison examines ancient Greek confederacies—the Amphictyonic council and the Achaean league—to illustrate the fatal weaknesses of loose unions. He shows how internal discord, ambition of powerful members, and foreign manipulation led to the ruin of these confederacies, arguing that the American Confederation suffers from similar defects and requires a stronger national government.

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.
