3. John C. Calhoun
John C. Calhoun, born on March 18, 1782, in Abbeville District, South Carolina, was a prominent political figure in the early 19th century. Serving as the seventh Vice President of the United States under both John Quincy Adams and Andrew Jackson, Calhoun was a staunch advocate for states’ rights and slavery. His aggressive defense of these positions, particularly during the Nullification Crisis, set the stage for the Civil War. Despite his significant influence, he never secured the presidency (britannica.com).
