Between the end of the Civil War and 1890, some African American baseball players played alongside white players in minor and major leagues. After 1890, Jim Crow segregation dominated the sport until Jackie Robinson integrated major league baseball in 1947. Consequently African Americans formed their own professional baseball leagues commonly and collectively known as Negro League baseball. During its heyday in the 1920s and 30s, the Negro Leagues drew large crowds and fielded over thirty teams throughout the East Coast and Midwest. In this primary source set, students will view original photographs, listen to oral history recordings, and read historical texts to gain a better understanding of of the lives and experiences of Negro League baseball players.
