The Great Heart of the Republic : Harvard University Press : 9780674052888 : 0674052889 : 21 Dec 2010 : The Civil War revealed what united as well as what divided Americans in the nineteenth century?not only in its deadly military conflict, but also in the broader battle of ideas, dueling moral systems, and competing national visions that preceded and followed. This cultural civil war was the clash among North, South, and West, as their leaders sought to shape Manifest Destiny and slavery politics. No site embodied this struggle more completely than St. Louis, the largest city along the border of slavery and freedom. In this sweeping history, Adam Arenson reveals a city at the heart of the cultural civil war.

They tried to reorient the nation's political landscape, with westerners in the vanguard and St. Louis as the cultural, commercial, and national capital. John C. Calhoun,
