“Not every former president uses their position for good. Franklin Pierce, a Northerner who favored popular sovereignty—the idea that democracy allowed citizens, and not the federal government, to decide if the territory in which they lived would allow slavery—tried to rally the living ex-presidents in 1861 to resolve the Civil War. But his efforts were torpedoed by Martin Van Buren, and Pierce became a vocal critic of Lincoln, a sympathizer for the South, and a correspondent of Confederate president Jefferson Davis. Worse still, Pierce’s predecessor, the Virginian John Tyler, defected from the Union and won a seat in the Confederate House of Representatives. He died a traitor in January 1862, and President Lincoln denied his predecessor a state funeral. Instead, Tyler was honored in Richmond, the Confederate capital.”
