Building an Antislavery Wall

In Building an Antislavery Wall, R. J. M. Blackett examines the efforts of black Americans in England to advance the cause of their own freedom. Speaking to enthusiastic working-class crowds in the cities and lobbying in the salons of the wealthy and aristocratic, black Americans used England as a forum to tell the world of their cruel plight in the United States, to expose what they saw as an oppressive slave society masquerading as the seat of democracy and freedom. It was their goal to create a moral cordon around the United States so that, in the words of Frederick Douglass, ""wherever a slaveholder went, he might hear nothing but denunciation of slavery, that he might be looked upon as a man-stealing, cradle-robbing, woman-stripping monster, and that he might see reproof and detestation on every hand.""

British support had monetary as well as symbolic value, and the popularity of the blacks as lecturers gave them a special edge in both fund-raising and proselytizing. At the same time, while organized white abolitionist societies expended much of their energy on sectarian disputes, the blacks sought to bridge these differences in the hope of marshaling the full weight of British opinion in their favor. The blacks played an especially important role, Blackett...
