While many historians look to internal conflict alone to explain the onset of the American Civil War, in The Problem of Emancipation, Edward Bartlett Rugemer places the origins of the war in a transatlantic context. Addressing a huge gap in the historiography of the antebellum United States, he explores the impact of Britain's abolition of slavery in 1834 on the coming of the war and reveals the strong influence of Britain's old Atlantic empire on the United States' politics. He demonstrates how American slaveholders and abolitionists alike borrowed from the antislavery movement developing on the transatlantic stage to fashion contradictory portrayals of abolition that became central to the arguments for and against American slavery. Richly researched and skillfully argued, The Problem of Emancipation explores a long-neglected aspect of American slavery and the history of the Atlantic World and bridges a gap in our understanding of the American Civil War.
