In 1856, South Carolina Congressman Preston Brooks assaulted Massachusetts Senator Charles Sumner with a cane in the United States Capitol, defending his family's honor and the rights of slaveholders. In beating Sumner unconscious, Brooks fueled a nationwide clash over slavery that ended in civil war.

Southern historian Paul Quigley brings Brooks to life more vividly than ever, revealing how his personal struggles shaped the fateful decision to attack Sumner. Raised in the slaveholding culture of honor and scarred by missed opportunities for glory in the Mexican-American War, Brooks came to believe in the redemptive power of violence. Quigley uses Brooks's life to examine the deeper currents propelling the United States to the brink of destruction. Brooks's story reveals the increasingly fraught relationship between words and violence. With the caning, Brooks sparked an ominous national debate over the righteousness of bloodshed in a polarized nation.

Examining enduring issues of masculinity, honor, and free speech, The Man Behind the Cane shows how words and violent behavior became perilously entangled in the fight over slavery and casts new light on the origins of the Civil War—and the ongoing dangers of political violence in our own time.
