Between 1803 and 1838, the United States, most famously personified by Andrew Jackson, fought a multifront war in the Deep South. In those years, the United States suppressed slave revolts and pacified whites still loyal to the European powers that had once controlled the region. These wars culminated in the ethnic cleansing of the Deep South. By the end of the 1830s, the Seminole, the Creek, the Chickasaw, the Choctaw and the Cherokee had all been “removed” to lands west of the Mississippi. Their expropriated land provided the foundation of the leading sector of the global economy in the first half of the 19th century.

In the 1830s, hundreds of millions of acres of conquered land were surveyed and put up for sale by the United States. This vast privatization of the public domain touched off one of the greatest economic booms in the history of the world up to that time. Investment capital from Britain, the Continent and the Northern states poured into the land market. “Under this stimulating process, prices rose like smoke,” the journalist Joseph Baldwin wrote in his memoir, “The Flush Times of Alabama and Mississippi.”

Without slavery, however, the survey maps of the General Land Office would have remained a sort of science-fiction plan for a society that could never happen. Between 1820 and 1860 more than a million enslaved people were transported from the upper to the lower South, the vast majority by the venture-capitalist slave traders the slaves called “soul drivers.” The first wave cleared the region for cultivation. “Forests were literally dragged out by the roots,” the former slave John Parker remembered in “His Promised Land.” Those who followed planted the fields in cotton, which they then protected, picked, packed and shipped — from “sunup to sundown” every day for the rest of their lives.
