Think of it like this — if American leaders had never made the *decision* to break away from Britain, America would still be a colony of Britain.
Decision making determines the course of events. This is because a certain decision will then trigger certain actions, which in the grand scheme of things will impact history.
Example; American leaders made the *decision* to break off from Britain, triggering the Revolutionary War and America’s Independence, thus that decision changed history.
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.
