I’m assuming you’re referring to Jim Crow not Slavery. The only difference between the north and south is that the south made it very difficult for blacks to vote and weren’t allowed to use the same water fountain. Other than that, whites in both areas made it difficult for Blacks to be upwardly mobile, using redlining and, yes, also using segregation (there is a old achool building thats a National Landmark in Hillburn, NY near Monsey, because that district didn’t desegregate until 1943).
