But of course, what defined "America" was still in question. Just as Garrison and others were naming their abolitionist society "American," South Carolinians were endeavoring to "nullify" federal laws. 1830ish showcased the end of one era (the making of "America" as a nation-state) and the beginning of a new one (the fracturing of "America" as a nation-state).
1830(ish) is far and away my favorite moment in time to teach. What's yours and why?
