What was the Iconoclastic Controversy?

Both Abraham Lincoln and Jefferson Davis had to deal with contentious congresses with often clashing interests and agendas. In Davis’ case the discord was intrinsic in the very “States’ Rights” concept behind the Confederacy, though in practice Lincoln had plenty of cat herding of his own to do. Lincoln was arguably the more successful president in having better political instincts, which became more evident as he grew into his presidency—a talent for knowing when and how to cajole, horse-trade, bribe outright or ruthlessly assert his power, depending on who he was dealing with.
