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.
A proclamation made by President Abraham Lincoln in 1863 that all slaves under the Confederacy were from then on âforever free.â. Note: In itself, the Emancipation Proclamation did not free any slaves, because it applied only to rebellious areas that the federal government did not then control. It did not affect the four slave states that stayed in the Union: Delaware, Maryland, Kentucky, and Missouri.
