Andrew Johnson never expected to be president. But just six weeks after becoming Abraham Lincoln's vice president, the events at Ford's Theatre thrust him into the nation's highest office. Johnson faced a nearly impossible task—to succeed America's greatest chief executive, to bind the nation's wounds after the Civil War, and to work with a Congress controlled by the so-called Radical Republicans. Annette Gordon-Reed, one of America's leading historians of slavery, shows how ill-suited Johnson was for this daunting task.

James A. Garfield may have been the most extraordinary man ever elected president. Born into abject poverty, he rose to become a wunderkind scholar, a Civil War hero, and a renowned and admired reformist congressman. Nominated for president against his will, he engaged in a fierce battle with the corrupt political establishment. But four months after his inauguration, a deranged office seeker tracked Garfield down and shot him in the back. But the shot didn’t kill Garfield. The drama of what hap­pened subsequently is a powerful story of a nation in tur­moil.

President Rutherford B. Hayes, the first Gilded Age president, began his career as an antislavery Union soldier. Yet the Compromise of 1877, which led to his prevailing in the wake of the hotly contested Hayes-Tilden elec­tion, caused Hayes to abandon Reconstruction and turn his attention to economic priorities such as using federal troops to subdue railroad strikes.

Despite his promising start as a young man, by his early 50s Chester A. Arthur was known as the crooked crony of New York machine boss Roscoe Conkling. For years Arthur had been perceived as unfit to govern, not only by critics and the vast majority of his fellow citizens but by his own conscience. As President James A. Garfield struggled for his life, Arthur knew better than his detractors that he failed to meet the high standard a president must uphold. And yet, from the moment President Arthur took office, he proved to be not just honest but brave.

President Franklin Pierce took steps to build new commercial relation­ships abroad, revamp the military, and restructure the federal courts. After an unprecedented landslide in the 1852 presidential election gave him supermajorities in the House and Senate, Pierce seemed poised for a productive presidency.
