The Antebellum City — Wealthiest in the South

By 1840, New Orleans had become the third-largest city in the United States and the wealthiest per capita in the South. The source of that wealth moved through the city in bales and hogsheads: cotton and sugar grown by enslaved people across the Mississippi Valley, shipped downriver to New Orleans wharves, sold through New Orleans banks, and loaded onto ships bound for Europe and the North. For several years in the 1830s and '40s, the city handled more exports than New York by value. What that money built is still here. The cast-iron galleries wrapping French Quarter balconies. The white-columned mansions spreading across the Garden District. The marble banks and exchanges rising in what became the Central Business District. All of it traces to the same ledger: the city's antebellum economy depended on the slave trade, and the nation's original sin is inseparable from New Orleans' prosperity in those years. The wealth is gone. The buildings remain. Walking the Quarter or the Garden District now means walking through what enslaved labor paid for—not as distant history, but as the iron you touch and the marble you pass. The city's formative wound is architectural.
