Professional historians, to varying degrees, believe that slavery was elemental to the coming of the Civil War. While there is disagreement as to the ways that the conflict over slavery and wage labor infused sectional differences, David Potter has arguably done more than any other scholar to forge a consensus on this issue. In Impending Crisis, he explores the different ways that slavery ignited the sectional conflict while refuting generalizations that describe the North and South as culturally different. Some saw the struggle as a clash of profoundly dissimilar cultures whose disparities transcended the difference over slavery. Others had a more economic opinion and viewed the conflict as a clash between economic interests of an emerging industrialist North and an agricultural South. A third viewpoint saw the conflict arising from different values between the sections. Potter’s criticism with these three arguments is that they all embellish the differences between the North and South and fail to see the similarities between the two regions. Potter displays how similar northerners and southerners were, and that a sense of American nationalism permeated both cultures more than historians have acknowledged.
Although the cultural, economic, and ideological explanations recognize slavery as an issue in sectional division, they neglect its significance within American culture. Potter shows how slavery was a key element to all three of the explanations for division. “Slavery, in one aspect or another, pervaded all of the aspects of sectionalism,” argues Potter (44). In spite of the American nationalism and cultural homogeneity between the North and South, the slavery issue intensified following the acquisition of new territory following the Mexican-American War and caused both northerners and southerners to lose sight of how much alike they were and how many values they shared. With a breakdown of the two-party system nationally, the Election of 1860 represented how much the slavery issue isolated the two regions as the young Republican party won a victory despite only receiving Northern votes. Not surprisingly, the breakup of the country followed soon after.
By placing slavery at the forefront of the conflict, Potter continues the debate over the main cause of the war. Was the war inevitable? Was slavery the main cause? Michael Holt has led a movement against Potter’s interpretation and responded with a study claiming that slavery was not the central reason, and that the breakdown of the two-party political system caused disunion. William Freehling’s work adds to the historiography by arguing that the South’s culture was not unified over slavery and that these internal divisions fostered anxieties, which fueled extremism. Future studies that elaborate from Potter’s traditional political narrative and infuse political culture will give a more complete analysis of 1850s. Not only understanding how Americans viewed singular events but also how they interpreted the world in which they lived will open new discussions about the causes of the war.
