Despite the onset of legal abolition in 1865, African American activists continued to be in the vanguard for defying transatlantic white supremacy in both the U.S. and the U.K. To irreversibly fulfil the failed promises of abolition, black women and men followed in the footsteps of their activist forebears to campaign and educate transatlantic audiences on global racism and the fact that, U.S. slavery had never actually died. Based on newly excavated written and oral testimonies, this article examines the broad motivations of why African Americans travelled to the British Isles post-1865 and published their narratives into the early twentieth century.
