The [[Negro National League (the first)|Negro National League]] was founded in {{baseball year|1920}} by [[Rube Foster]], independent of the [[National Baseball Commission]] (1903–1920). The NNL survived through 1931, primarily in the midwest, accompanied by the major [[Eastern Colored League]] for several seasons to 1928. "National" and "American" [[Negro league baseball|Negro leagues]] were established in 1933 and 1937 which persisted until integration. The [[Negro Southern League (1920–36)|Negro Southern League]] operated consecutively from 1920, usually at a lower level. None of them, nor any integrated teams, were members of Organized Baseball, the system led by Commissioner [[Kenesaw Mountain Landis]] from 1921. Rather, until {{baseball year|1946}} professional baseball in the United States was played in two racially segregated league systems, one on each side of the so-called color line. Much of that time there were two high-level "Negro major leagues" with a championship playoff or all-star game, as between the white major leagues.
