Slave Country tells the story of the expansion of slavery in the new United States. In the wake of the American Revolution, slavery gradually disappeared from the northern states and the importation of captive Africans was prohibited. Yet, at the same time, the country's slave population grew, new plantation crops appeared, and several new slave states joined the Union. Adam Rothman explores how slavery flourished in a new nation dedicated to the principle of equality among free men, and reveals the enormous consequences of U.S. expansion into the region that became the Deep South.
