In 1920, National Negro Baseball League franchises began operating in cities with large black populations, such as New York City, New York; Newark, New Jersey; Philadelphia, Pennsylvania; St. Louis, Missouri; and Baltimore, Maryland. The League consists of the Kansas City Monarchs, Indianapolis ABC's, Dayton Marcos, Chicago American Giants, Detroit Stars, St. Louis Stars, and more. A year after Rube Foster died in 1930, the league stopped. However, in 1933, Gus Greenlee, the Pittsburgh numbers boos who owned the Pittsburgh Crawfords brought back another version of the Negro National League. The league later included the Homestead Grays, who won the league championship in 1942.
