Exploring Causes of the Civil War – Part VII: Political Discord, Slavery, and the Fight for Political Control


William E. GienappPolitical discord represents yet another candidate for the war’s cause. Late historian William E. Gienapp (pictured right) suggests that “however much social and economic developments fueled the sectional conflict, the coming of the Civil War must be explained ultimately in political terms, for the outbreak of war in April 1861 represented the complete breakdown of the American political system. As such, the Civil War constituted the greatest single failure of American democracy.”[i]

Gienapp poinSlave Sale Posterts to the role of slavery as the underlying cause of the sectional conflict. “Without slavery it is impossible to imagine a war between the North and the South (or indeed, the existence of anything we would call “the South” except as a geographic region).”[ii] He also asserts that America’s slave heritage was completely associated with race. That is, had the slaves brought to America been white, the practice would have disappeared much earlier.[iii] But an argument asserting slavery as chief cause of the war neglects the fact that not only was it older than the republic, but “for over half a century following adoption of the Constitution, the institution had only sporadically been an issue in national politics, and it had never dominated state politics in either section.”[iv] What changed? It was the rise of the slavery issue in American society; that is, the heightened awareness of it. This development was rooted in a number of changes in American society in the first half of the nineteenth century already addressed.[v]

As mentioned in previous posts in this series, the abolitionist movement did a great deal to raise that awareness. But Gienapp suggests that “it was the politicians themselves, as part of the struggle for control of the two major parties, whJames Polko ultimately injected the slavery issue into national politics.”[vi] The key development was the introduction in Congress in 1846 of the Wilmot Proviso, which prohibited slavery from any territory acquired from Mexico, by a group of Van Burenite Democrats who were angry with President James K. Polk (pictured right) and his southern advisers. Once the slavery issue, in the shape of the question of its expansion into the western territories, entered the political arena, it proved impossible to get it out. The issue took on a life of its own, and when politicians tried to drop the issue after 1850, they discovered that many voters were unwilling to acquiesce.[vii]

Gienapp makes a good case for the war’s true cause in the following discourse.

A second critical development, intimately related to the first, was the crystallization of rival sectional ideologies oriented toward protecting white equality and opportunity. Increasingly, each section came to see the other section and its institutions as a threat to its vital social, political, and economic interests. Increasingly, each came to think that one section or the other had to be dominant. Informed by these ideologies, a majority of the residents of each section feared the other, and well before the fighting started the sectional conflict represented a struggle for control of the nation’s future.

It fell to the political system to adjudicate differences between the sections and preserve a feeling of mutual cooperation and unity. And for a long time the political system had successfully defused sectional tensions. Because it brought northern and southern leaders together, Congress was the primary arena for hammering out solutions to sectional problems. In various sectional confrontations–the struggle over the admissiLecompton Constitutionon of Missouri as a slave state in 1819-21, the controversy over nullification and the tariff in 1833, the problem of the status of slavery in the territory acquired from Mexico in 1850, and the struggle over the proslavery Lecompton constitution in 1858-Congress had always managed to find some acceptable way out of the crisis.

Yet the American political system was particularly vulnerable to sectional strains and tensions. One reason was the institutional structure of American politics. The Civil War occurred within a particular political institutional framework that, while it did not make the war inevitable, was essential to the coming of the war.

Integral to this institutional framework was the United States Constitution. While some aspects of the Constitution retarded the development of sectionalism, it contained a number of provisions that strengthened the forces of sectional division in the nation. No constitution can anticipate all future developments and conclusively deal with all controversies that subsequently arise. The purpose in analyzing the Constitution’s role in the sectional conflict is not to fault its drafters or condemn it as a flawed document, but rather to indicate the importance of certain of its clauses for the origins of the war.

One signifiAndrew Moorecant feature of the Constitution was its provision for amendment. Lurking beneath the surface in the slavery controversy was white Southerners’ fear that the Constitution would be amended to interfere with the institution. In advocating secession after Abraham Lincoln’s election, Governor Andrew B. Moore of Alabama (pictured above) predicted that the Republicans would quickly create a number of new free states in the West, which “in hot haste will be admitted to the Union, until they have a majority to alter the Constitution. Then slavery will be abolished by law in the States.”[viii]

The fear, uncertainty and doubt associated with this possibility, on the part of the Southern political establishment, pushed the country toward war.
