Zachary Taylor, a professional soldier and sugar planter with no previous political experience, held the office of president for barely sixteen months before dying of acute gastroenteritis. A war hero before moving into the White House, he immediately confronted a rogue effort to seize Cuba and had to address issues involving slavery in the new territories acquired from Mexico.

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.

Often remembered as the president who died shortly after taking office, William Henry Harrison remains misunderstood by most Americans. Before becoming the ninth president of the United States in 1841, Harrison was instrumental in shaping the early years of westward expansion. Robert M. Owens now explores that era through the lens of Harrison’s career, providing a new synthesis of his role in the political development of Indiana Territory and in shaping Indian policy in the Old Northwest.

Millard Fillmore, who fell into the presidency when Zachary Taylor died unexpectedly, is often regarded as a weak leader and a failed chief executive. Eager to show that he could heal the rift between North and South, Fillmore reversed some of Taylor’s cautious policies. He zealously supported the controversial Compromise of 1850, which some historians believe worsened the sectional divide.

He's the butt of political jokes, frequently subjected to ridicule, and almost never absent a "Worst Presidents" list where he most often ends up at the bottom. Historians have labeled him the "Worst President Ever," "Dead Last," "Unfit," and "Incompetent," to name but a few. Many contemporaries were equally cruel. H. L. Mencken called him a "nitwit." To Alice Roosevelt Longworth, he was a "slob."
