Professional baseball league for blacks founded in 1920 by pitcher Andrew Rube Foster. During Jim Crow era, Major League Baseball excluded blacks so they formed their own teams with blacks in all key roles. The Negro League was widely successful and supported in black communities. Other black leagues followed, including Eastern Colored League and Southern Negro League. Jackie Robinson integrated Major League Baseball in 1947. Last black clubs folded in the early 1960s.
