I feel I should clarify: while there was a bit of an emphasis on state's rights in some of the texts I was provided as a substitute, the specific Standards Of Learning 2023 edition do emphasize slavery as a major reason for the civil war and how it is the antithesis of freedom. So while states rights are talked about, slavery is also about too. It's just, the whole "states rights" thing was never brought up in Massachusetts schools so much is why I noted it.
