A People's History of the United States

The United States government's support of slavery was based on an overpowering practicality. In 1790, a thousand tons of cotton were being produced every year in the South. By 1860, it was a million tons. In the same period, 500,000 slaves grew to 4 million. A system harried by slave rebellions and conspiracies (Gabriel Prosser, 1800; Denmark Vesey, 1822; Nat Turner, 1831) developed a network of controls in the southern states, hacked by the laws, courts, armed forces, and race prejudice of the nation's political leaders.

It would take either a full-scale slave rebellion or a full-scale war to end such a deeply entrenched system. If a rebellion, it might get out of hand, and turn its ferocity beyond slavery to the most successful system of capitalist enrichment in the world. If a war, those who made the war would organize its consequences. Hence, it was Abraham Lincoln who freed the slaves, not John Brown. In 1859, John Brown was hanged, with federal complicity, for attempting to do by small-scale violence what Lincoln would do by large-scale violence several years later-end slavery.
