Blacks were not slaves in the North it was the southern slaves found their way north where their black counterparts got them to Canada. You are probably looking up the democrat version of what happened and democrats have lied all the way through because they were the ones that wanted slavery, they were the ones that wanted blacks kept to heel, they were the ones that started the KKK. They spent years lying and lying and lying to blame someone else. Democrats always blame someone else when they do things look at BLM ANTIFA. What you never ever ever hear is that 6000 white boys died fighting to free the slaves. I wish they hadntnt then none of BLM would be here now to destroy everyones life.
