This work traces professional football's movement from segregation to integration, beginning with a discussion of the various reasons why the game was first segregated. It describes the schemes that NFL owners came up with to ban African Americans from the league in the 1930s and 1940s, and tells how these barriers broke down after World War II. The author considers how professional football overcame the legacies of Jim Crow and how Jim Crow laws may still haunt the game.
