When Jefferson acquired the Louisiana Territory, he envisioned an “empire for liberty” populated by self-sufficient white farmers. Cleared of Native Americans and the remnants of European empires by Andrew Jackson, the Mississippi Valley was transformed instead into a booming capitalist economy commanded by wealthy planters, powered by steam engines, and dependent on the coerced labor of slaves. River of Dark Dreams places the Cotton Kingdom at the center of worldwide webs of exchange and exploitation that extended across oceans and drove an insatiable hunger for new lands. This bold reaccounting dramatically alters our understanding of American slavery and its role in U.S. expansionism, global capitalism, and the upcoming Civil War.
