Answer:
Violence & Bloodshed (hence the term for the event "Bleeding Kansas") arose when slave-owning & pro-slavery settlers as well as free settlers moved into the territory of Kansas, and both sides fought in a literal all-out war to see if Kansas was to be admitted as a free or slave state. However, Kansas was admitted as a free state to the Union, and was a prologue to what will later become known as the American Civil War, as the uneasy peace and failure to balance powers became the eventual stepping stones towards the South declaring independence.
