The role the rural South and its plantation system played in the secession of the Confederate states is well established, but historian Frank Towers contends that we should look just as closely at the South's urban centers. An exemplary feat of research, The Urban South and the Coming of the Civil War sheds light on the dynamics of secession by concentrating on pivotal sociopolitical shifts in the South's three largest cities - Baltimore, New Orleans, and St. Louis. Despite having a culture and an economy rooted in agriculture, between 1840 and 1860 the South actually experienced greater growth in its cities than in its rural sectors. Attracted to the cities by jobs in commerce and industry, propertyless white workingmen developed a slave-state variant of the free-labor politics that Abraham Lincoln's Republican Party used to gain prominence in the North. Lacking the sort of national organization that could contribute to the cause through patronage and legislation, parties such as Baltimore's Know-Nothings relied instead on a combination of nativism, labor-supported machine politics, and electoral coercion.
By the late 1850s, the Democratic Party dominated the state legislatures of Louisiana, Missouri, and Maryland, and yet it had lost all of those states' largest cities. Towers shows how the ascendance of urban opposition parties hastened the collapse of the Jacksonian party system. Although they were proslavery, urban voters favored workers' rights and stronger municipal government, both of which threatened the landowning society, particularly in light of prospective urban alliances with Washington. Fearing the horrors of mob rule and the slim chances of slavery's survival in an atmosphere of working-class politics, rural planters largely abandoned the traditional Whig-Democrat competition and banded together in a more staunchly secessionist position. The Urban South and the Coming of the Civil War makes clear that this shift played a critical role in placing the South on an unalterable path toward war.
