"In the decades prior to the American Civil War, as many as two million enslaved African Americans were sold and often relocated through the domestic slave trade. The two largest slave markets of the 1850s, Richmond, Virginia, and New Orleans, Louisiana, both developed significant architectural and economic infrastructure that supported the trade. By examining the architecture of the trade and mapping its location in each city, this article examines the distinct character of the trade in each city and explores what those differences reveal about the distinct place of slavery in each region's economy."
