Ever heard of the Underground Railroad?
Most of the data I have given in this thread is from a book by James Ronald Kennedy and Walter Donald Kennedy. They cite a bazillion original sources.
Ah, there it is, better late than never.
Lol. Or course. The few who helped with that are NOT representative of the majority of Northerners' sentiments towards blacks. If you have studied the war and etc. you should know that abolitionists were a minority. We hear a lot about them today, but they were only a small group of people and did NOT represent the feeling of most Northerners towards blacks. Again, have you read the post upthread about many Northern states barring blacks from entering and Northerners saying they want the territories slave free because they want those lands reserved for white labor and white labor only?
