Faced with the Great Depression and World War II, Franklin D. Roosevelt, nicknamed “FDR,” guided America through its greatest domestic crisis, with the exception of the Civil War, and its greatest foreign crisis. His presidency—which spanned twelve years—was unparalleled, not only in length but in scope. FDR took office with the country mired in a horrible and debilitating economic depression that not only sapped its material wealth and spiritual strength, but cast a pall over its future. Roosevelt's combination of confidence, optimism, and political savvy—all of which came together in the experimental economic and social programs of the "New Deal"—helped bring about the beginnings of a national recovery.
