Step-by-step explanation:
In the early 1800s, abolitionists wanted to change US society by advocating for the immediate end of slavery and the creation of a multiracial society based on equality between black and white people. They used moral arguments, known as moral suasion, to highlight the immorality of slavery and hoped to bring about a mass conversion in public opinion.
