There were 9 US presidents that had slaves at some time. These were George Washington, Thomas Jefferson, James Madison, Andrew Jackson, John Tyler, James K. Polk, Zachary Tayl â¦ or, Andrew Johnson, and Ulysses S. Grant.
Itâs a commonplace that Abraham Lincoln never trafficked in slaves, much less owned them â indeed, he âfreed the slaves.â But hereâs the shocker: Although the slave trade had been abolished in the District of Columbia in 1850, slaves inhabited the capital for another 15 years â till the end of the Civil War.
