The Federalist Papers · Federalist No. 9 · paragraph 5

The utility of a Confederacy, as well to suppress faction and to guard the internal tranquillity of States, as to increase their external force and security, is in reality not a new idea. It has been practiced upon in different countries and ages, and has received the sanction of the most approved writers on the subject of politics. The opponents of the plan proposed have, with great assiduity, cited and circulated the observations of Montesquieu on the necessity of a contracted territory for a republican government. But they seem not to have been apprised of the sentiments of that great man expressed in another part of his work, nor to have adverted to the consequences of the principle to which they subscribe with such ready acquiescence.
