By 1808, the United States abolished the transatlantic slave trade, formally ending the three-century-long forced migration of Africans to the American hemisphere.
But that did not end slavery in the United States. Nor did it stop the black-market importation of enslaved Africans into the United States or the trading of slaves between the states. By the time of the Louisiana Purchase enslaved Blacks were roughly 20 percent of this nation’ s population. The buying and selling of these people – and their progeny – within the United States would continue for nearly 60 years.
The Louisiana Purchase was made during the presidency of Thomas Jefferson, who is credited with being the primary author of the Declaration of Independence – which has been called the“ birth certificate” of a worldwide movement for selfdetermination. But Jefferson, who enslaved more than 600 Blacks during his lifetime, deserves credit of a more heinous kind. He freed only seven of his slaves – believed to have been the children he fathered with Sally Hemings, the enslaved sister of Robert Hemings.
The War of 1812 marked yet another turning point in the struggle to end slavery in the United States.
President James Madison declared war on Britain on June 18, 1812, after nearly a decade of British warships seizing American ships at sea stealing their cargo and forcing the crews to serve in the British navy. England also stoked the ire of its former colonies by giving support to Native American tribes that resisted the seizure of their land by American settlers.

But while both sides in the conflict appealed to enslaved Blacks to join the fight on their side, the United States largely reneged on its promise of freedom to those who did so. The British lured 4,000 to 5,000 runaway slaves to join its forces with promises of equal pay and freedom from their enslavement. It kept both promises – paying Black recruits the same as its White soldiers and resettling them to other British territories, like Bermuda, Trinidad, and Nova Scotia.
One British unit of Black runaways, called the Corps of Colonial Marines, fought in the Battle of Bladensburg in which American troops defending Washington were routed. With the
