What were the Negro Leagues?

"This baseball league that was made up of African American players and run by African American owners ushered in the biggest change in the history of baseball. In America during the early twentieth century, no part was safe from segregation, not even the country's national pastime, baseball. Despite their exodus from the Major Leagues because of the color of their skin, African American men still found a way to participate in the sport they loved. [This book] shines a spotlight on the players, coaches, owners, and teams that dominated the Negro Leagues during the 1930s and 40s. Readers will learn about how phenomenal players like Satchel Paige, Josh Gibson, and of course, Jackie Robinson greatly changed the sport of baseball"--OCLc.
