The issue of slavery proved especially combustible in the reform-minded antebellum United States. Those who hoped to end slavery had different ideas about how to do it. Some could not envision a biracial society and advocated sending blacks to Africa or the Caribbean. Others promoted the use of violence as the best method to bring American slavery to an end. Abolitionists, by contrast, worked to end slavery and to create a multiracial society of equals using moral arguments—moral suasion—to highlight the immorality of slavery. In keeping with the religious fervor of the era, abolitionists hoped to bring about a mass conversion in public opinion to end slavery.
