The war between the AL and NL caused shock waves throughout the baseball world. At a meeting at the Leland Hotel in Chicago in 1901, the other baseball leagues negotiated a plan to maintain their independence. A new National Association was formed to oversee these minor leagues. While the NA continues to this day (known as Minor League Baseball), at the time Ban Johnson saw it as a tool to end threats from smaller rivals who might expand in other territories and threaten his league's dominance.
