Why did the bleeding Kansas start?

Answer 1

When Kansas decided to become part of the U.S.A. it was given the decision to become a slave state of a state that was free to slaves. When it came time to vote, the Southerners went to Kansas and acted like they where from Kansas. They, of course voted for slavery, and so it became a slave state. Once the people from the north found out about this, they where not happy. They told a judge but the judge did not do anything, so the U.S.A. attacked the south, which was called bleeding kansas

was it because john brown attacked kansa and killed 5 black mens
