The Toledo Blue Stockings formed as a minor league baseball team in Toledo, Ohio, in 1883. They won the Northwestern League championship in 1883. Their home ballpark was League Park. The following year, they joined the major league American Association. That year, they finished 8th with a 46–58 record. The team returned to the minors the next year and disbanded after the 1885 season.
The team was the only major league team with black players (brothers Moses Fleetwood Walker and Weldy Walker) prior to Jackie Robinson's appearance with the Brooklyn Dodgers in 1947. This was before baseball's color barrier had been firmly established in 1887.
