From Ohio History Central
The Columbus Bluebirds 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 Columbus Bluebirds played its home games in Columbus, Ohio. The team played in the Negro National League. The team played in Columbus for only part of the year in 1933. During the middle of the season, the Columbus Bluebirds relocated from Columbus to Cleveland, Ohio, and became the Cleveland Giants. The Cleveland Giants played only two seasons (1933 and 1934) before disbanding. For the 1934 season, the team became known as the Cleveland Red Sox.
