League Alliance
The League Alliance was the first semi-affiliated minor league baseball league. Proposed by Al Spalding on January 15, 1877. Independent baseball teams were to affiliate with National League teams, which would honor their respective contracts. The league only existed for one season, 1877, though another version was attempted in 1882. Teams
