Federalist Papers 5B

The history of Great Britain is the one with which we are in general the best acquainted, and it gives us many useful lessons. We may profit by their experience without paying the price which it cost them. Although it seems obvious to common sense that the people of such an island should be but one nation, yet we find that they were for ages divided into three, and that those three were almost constantly embroiled in quarrels and wars with one another. Notwithstanding their true interest with respect to the continental nations was really the same, yet by the arts and policy and practices of those nations, their mutual jealousies were perpetually kept inflamed, and for a long series of years they were far more inconvenient and troublesome than they were useful and assisting to each other.

Should the people of America divide themselves into three or four nations, would not the same thing happen? Would not similar jealousies arise, and be in like manner cherished? Instead of their being "joined in affection" and free from all apprehension of different "interests," envy and jealousy would soon extinguish confidence and affection, and the partial interests of each confederacy, instead of the general interests of all America, would be the only objects of their policy and pursuits. Hence, like most other BORDERING nations, they would always be either involved in disputes and war, or live in the constant apprehension of them.
