From Ohio History Central
The Cleveland Giants was a professional African American baseball team.
During the late 1800s and the early 1900s, professional baseball teams and leagues were segregated. African Americans did not play on teams with white players. White teams and black teams did not play in the same professional leagues. As a result of this segregation, there were separate leagues and teams for whites and blacks in professional baseball's early decades.
The Cleveland Giants played its home games in Cleveland, Ohio. The team played in the Negro National League. In 1933, the Columbus Bluebirds relocated from Columbus, Ohio, to Cleveland and became the Cleveland Giants. The Cleveland Giants played only two seasons (1933 and 1934) before disbanding. In the 1934 season, the team was known as the Cleveland Red Sox.
