I have often seen threads that state Northerners did not care about slavery. But how true is this? There were no modern polling done in 1869 so we must find a way to judge this. Not every Notherner was a radical abolitionist, and not every Northerners voted Republican. Keeping slavery out of the territories could give us some indication, but self interest can not be completely ignored. Would the fact slavery was outlawed in Northern States be useful to judge? Again self interest in limiting competition with free labor could be a factor. I am not sure that Northerners who did not believe in forcing Southern States to give up slavery did not find the concept of slavery immoral. How do we judge if Northerners supported the concept of slavery?
