Many abolitionists spoke out against slavery citing its
cruelty and its effects on society. Many
former slaves like Frederick Douglas spoke of his experience as a slave and his
eloquent speeches made people realize that Blacks had the potential to do great
things. They also distributed pamphlets
and reading materials on the evils of slavery.
The most successful propaganda that they made was the book Uncle Tom’s
Cabin where it opened the eyes of the public about the cruelties of slavery.
