In the early 1900s, African Americans faced widespread discrimination. Professional baseball leagues banned Black ballplayers. So African Americans formed their own professional baseball leagues. This book explores the history of these leagues and their legacy today. Easy-to-read text, vivid images, and helpful back matter give readers a clear look at this subject. Features include a table of contents, infographics, a glossary, additional resources, and an index. Aligned to Common Core Standards and correlated to state standards. Core Library is an imprint of Abdo Publishing, a division of ABDO.
