Answer: Iconoclastic Controversy, a dispute over the use of religious images (icons) in the Byzantine Empire in the 8th and 9th centuries. The Iconoclasts (those who rejected images) objected to icon veneration for several reasons, including the Old Testament prohibition against images in the Ten Commandments (Exodus 20:4) and the possibility of idolatry.
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.
