The Reinvention of Atlantic Slavery shows how, at a moment of crisis after the Age of Revolutions, ambitious planters in the Upper US South, Cuba, and Brazil forged a new set of relationships with one another to sidestep the financial dominance of Great Britain and the northeastern United States. They hired a transnational group of chemists, engineers, and other "plantation experts" to assist them in adapting the technologies of the Industrial Revolution to suit "tropical" needs and maintain profitability. These experts depended on the know-how of slaves alongside whom they worked. Bondspeople with industrial craft skills played key roles in the development of new production technologies like sugar mills. While the very existence of skilled enslaved workers contradicted the racial ideologies underpinning slavery and allowed black people to wield new kinds of authority within the plantation world, their contributions reinforced the economic dynamism of the slave economies of Cuba, Brazil, and the Upper South. When separate wars broke out in all three locations in the 1860s, the transnational bloc of masters and experts took up arms to perpetuate the Greater Caribbean they had built throughout the 1840s and 1850s. Slaves played key wartime roles on the opposing side, helping put an end to chattel slavery. However, the worldwide racial division of labor that emerged from the reinvented plantation complex has proved more durable.

The period of the "second slavery" was marked by geographic expansion of zones of slavery into the Upper US South, Cuba, and Brazil and chronological expansion into the industrial age.As The Reinvention of Atlantic Slavery shows, ambitious planters throughout the Greater Caribbean hired a transnational group of chemists, engineers, and other "plantation experts" to assist them in adapting industrial technologies to suit their "tropical" needs and increase profitability. Not only were technologies reinvented so as to keep manufacturing processes local but slaveholders' adaptation of new racial ideologies also shaped their particular usage of new machines. Finally, these businessmen forged a new set of relationships with one another in order to sidestep the financial dominance of Great Britain and the northeastern United States. In addition to promoting new forms of mechanization, the technical experts depended on the know-how of slaves alongside whom they worked. Bondspeople with industrial craft skills played key roles in the development of new production processes and technologies like sugar mills. While the very existence of such skilled slaves contradicted prevailing racial ideologies and allowed black people to wield power in their own interest, their contributions grew the slave economies of Cuba, Brazil, and the Upper South. Together reform-minded planters, technical experts, and enslaved people modernized sugar plantations in Louisiana and Cuba; brought together rural Virginia wheat planters and industrial flour-millers in Richmond with the coffee-planting system of southeastern Brazil; and enabled engineers and iron-makers in Virginia to collaborate with railroad and sugar entrepreneurs in Cuba. Through his examination of the creation of these industrial bodies of knowledge, Daniel B. Rood demonstrates the deepening dependence of the Atlantic economy on forced labor after a few revolutionary decades in which it seemed the institution of slavery might be destroyed. The reinvention of this plantation world in the 1840s and 1850s brought a renewed movement in the 1860s, especially from enslaved people themselves in the United States and Cuba, to end chattel slavery. This account of capitalism, technology, and slavery offers new perspectives on the nineteenth-century Americas.
