William Henry Harrison died just 31 days after taking the oath of office in 1841. Today he is a curiosity in American history, but as Collins shows in this entertaining and revelatory biography, he and his career are worth a closer look.

The first president born after America's independence ushers in a new era of no-holds-barred democracy The first "professional politician" to become president, the slick and dandyish Martin Van Buren was to all appearances the opposite of his predecessor, the rugged general and Democratic champion Andrew Jackson. Van Buren, a native Dutch speaker, was America's first ethnic president as well as the first New Yorker to hold the office, at a time when Manhattan was bursting with new arrivals. A sharp and adroit political operator, he established himself as a powerhouse in New York, becoming a U.S. senator, secretary of state, and vice president under Jackson, whose election he managed. His ascendancy to the Oval Office was virtually a foregone conclusion. Once he had the reins of power, however, Van Buren found the road quite a bit rougher. His attempts to find a middle ground on the most pressing issues of his day-such as the growing regional conflict over slavery-eroded his effectiveness. But it was his inability to prevent the great banking panic of 1837, and the ensuing depression, that all but ensured his fall from grace and made him the third president to be denied a second term. His many years of outfoxing his opponents finally caught up with him. Ted Widmer, a veteran of the Clinton White House, vividly brings to life the chaos and contention that plagued Van Buren's presidency-and ultimately offered an early lesson in the power of democracy.

The oddly named president whose shortsightedness and stubbornness fractured the nation and sowed the seeds of civil war In the summer of 1850, America was at a terrible crossroads. Congress was in an uproar over slavery, and it was not clear if a compromise could be found. In the midst of the debate, President Zachary Taylor suddenly took ill and died. The presidency, and the crisis, now fell to the little-known vice president from upstate New York. In this eye-opening biography, the legal scholar and historian Paul Finkelman reveals how Millard Fillmore's response to the crisis he inherited set the country on a dangerous path that led to the Civil War. He shows how Fillmore stubbornly catered to the South, alienating his fellow Northerners and creating a fatal rift in the Whig Party, which would soon disappear from American politics—as would Fillmore himself, after failing to regain the White House under the banner of the anti-immigrant and anti-Catholic "Know Nothing" Party. Though Fillmore did have an eye toward the future, dispatching Commodore Matthew Perry on the famous voyage that opened Japan to the West and on the central issues of the age—immigration, religious toleration, and most of all slavery—his myopic vision led to the destruction of his presidency, his party, and ultimately, the Union itself.

The rough-hewn general who rose to the nation's highest office, and whose presidency witnessed the first political skirmishes that would lead to the Civil War Zachary Taylor was a soldier's soldier, a man who lived up to his nickname, "Old Rough and Ready." Having risen through the ranks of the U.S. Army, he achieved his greatest success in the Mexican War, propelling him to the nation's highest office in the election of 1848. He was the first man to have been elected president without having held a lower political office. John S. D. Eisenhower, the son of another soldier-president, shows how Taylor rose to the presidency, where he confronted the most contentious political issue of his age: slavery. The political storm reached a crescendo in 1849, when California, newly populated after the Gold Rush, applied for statehood with an anti- slavery constitution, an event that upset the delicate balance of slave and free states and pushed both sides to the brink. As the acrimonious debate intensified, Taylor stood his ground in favor of California's admission—despite being a slaveholder himself—but in July 1850 he unexpectedly took ill, and within a week he was dead. His truncated presidency had exposed the fateful rift that would soon tear the country apart.
