Titled "The Same Subject Continued: The Insufficiency of the Present Confederation to Preserve the Union", Madison Continues the argument advanced by Alexander Hamilton regarding the failures of the Articles of Confederation.
Madison highlights parallels between the history of Ancient Greece and the Confederation, and uses these points to illustrate the importance of bringing the union closer together. He points out that the Achaean and Amphictyonic Leagues both ended in despotism and dissolution.
