> It’s widely accepted today that the Civil War was about slavery.
That's a bit too simplified. The South fought primarily because they wanted to keep slavery and thought Lincoln would abolish it, but the North fought primarily to prevent secession, and ending slavery was just a convenient tool they could use to help win the war. The "good north vs evil south" narrative is too often used as a political cudgel, and doesn't really accurately reflect the on-the-ground reality.
