On May 22, 1856, in the United States Congress, Representative Preston Brooks attacked Senator Charles Sumner with a walking cane in retaliation for a speech given by Sumner two days earlier. The beating nearly killed Sumner and it drew a sharply polarized response from the American public on the subject of the expansion of slavery in the United States. It has been considered symbolic of the "breakdown of reasoned discourse"[1] that eventually led to the American Civil War.
