During the nineteenth century and especially after the Civil War, scores of black abolitionists like Frederick Douglass, Moses Roper and Ellen Craft travelled to England, Ireland, Scotland, and parts of rural Wales to educate the public on slavery. By sharing their oratorical, visual, and literary testimony to transatlantic audiences, African American activists galvanised the antislavery movement, which had severe consequences for former slaveholders, pro-slavery defenders, white racists, and ignorant publics. Their journeys highlighted not only their death-defying escapes from bondage but also their desire to speak out against slavery and white supremacy on foreign soil. Hannah-Rose Murray explores the radical transatlantic journeys formerly enslaved individuals made to the British Isles, and what light they shed on our understanding of the abolitionist movement. She uncovers the reasons why activists visited certain locations, how they adapted to the local political and social climate, and what impact their activism had on British society.
