This also declared the Missouri Compromise unconstitutional, because it limited slavery in a territory. This gave great joy to the South but enraged the North. This was another sign of sectionalism. Sectionalism is what led to the War. A true sign of the sectionalism of the United States was the comment by James Henry Hammond to the Northern Delegation after the caning of Sumner.
Cotton is King.
This statement divided the country up even more, by Cotton in the South and Manufacturing in the North. A representation of the willingness of violence in the Senate was best shown with the caning of Senator Charles Sumner of Massachusetts. Senator Sumner was caned after verbally assaulting a southern Senator. The southern Senator's nephew, Preston Brooks, beat Sumner so severely that he couldn't return to the Senate for four years. This was a sick representation of the temperament that the south had.
