Answer:
The Caning of Charles Sumner, or the Brooks–Sumner Affair, occurred on May 22, 1856, in the United States Senate chamber, when Representative Preston Brooks, a pro-slavery Democrat from South Carolina, used a walking cane to attack Senator Charles Sumner, an abolitionist Republican from Massachusetts, in retaliation for a speech given by Sumner two days earlier in which he fiercely criticized slaveholders, including a relative of Brooks. The beating nearly killed Sumner and it contributed significantly to the country's polarization over the issue of slavery. It has been considered symbolic of the "breakdown of reasoned discourse"[1] and the use of violence that eventually led to the Civil War.
