Trumbull, Lyman (1813-1896), was an American political leader. He strongly opposed slavery. As a United States senator, he supported President Abraham Lincoln during the American Civil War (1861-1865), and helped frame Amendment 13 to the U.S. Constitution, which abolished slavery. Trumbull guided Amendment 14, guaranteeing the rights of African Americans, through Congress. He voted against conviction after President Andrew Johnson's impeachment in 1868.
