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.
Either: How many presidents owned slaves at some point in their lives? Or: How many presidents owned slaves while serving as chief executive? Many books get the answers to these questions wrong, and when I speak on the presidents and ask these two questions, audiences invariably low-ball the answer to both.
