An independent baseball league is a professional baseball organization located in the United States and Canada that is not operated in conjunction with either a Major League Baseball team or an affiliated Minor League Baseball team.  Being independent allows teams to be located close to major league teams without their consent.  Such leagues have been around for many years and were once known as "outlaw leagues" due to their position outside the rules of affiliated minor league baseball.
