Again, not actually true up north. You (and I) were “trained” to think nationally, not a state by state basis. Freed blacks did vote in 9 states at one point long before the Civil War. In one example, North Carolina legislators in 1835 voted 66 for eliminating freed blacks from voting and 61 whites voted for keeping their right to vote. That state constitution was thus changed to take away their rights and repress them. Women in New Jersey had a right to vote for a few elections around 1800, before having it taken away. White “peasants” who didn’t own land in Kentucky gave them the right to vote and even briefly had given freed blacks the right to vote before rescinding it. There are many examples of this struggle to vote spread out across the states in the first period up until 1860, but like this example from Rosa Parks, they’ve been eliminated. (I won’t mention the blacks voting in Rapides Parish in 1835 as that seems not possible under any narrative, and the white in the rest of the state were infuriated and rewrote that triumph out of the historical narrative).
