Abolitionists went on speaking tours to preach and speak about god and to get rid of slavery. They tried to influence slave owners and other plantation owners to change their minds about slaves freedoms
As all this was going on with people trying to abolish slavery slaves were trying to escape through the underground railroad. They would go to houses that had secret hiding spots for the slaves to hide from the white men looking for them
The slaves would travel at night so they wouldn't be caught and they could hide and travel better and further.
