The league was conceived both as an official Triple-A minor league circuit and member of the National Association of Professional Baseball Leagues. It was composed of six clubs unaffiliated with Major League Baseball farm systems.
The Inter-American loop was headed by Roberto Maduro, former owner of the Triple-A Havana Sugar Kings and a longtime scout and front-office executive active in Latin American countries and Major League Baseball.
A 130-game regular season was planned, while the six teams were located in the United States (2), Panama, Puerto Rico, the Dominican Republic and Venezuela. The league featured several well-known MLB veterans, with rosters averaging players between 26-29 years of age.
But the new circuit was barely able to complete half its schedule, fatally wounded by "under-capitalized owners, internecine rivalries among Caribbean baseball powers, tropical monsoons, and unreliable air travel."
On June 17, 1979, the Panama and Puerto Rico teams disbanded, leaving the league with only four clubs. Thirteen days later, the entire league folded. The Miami Amigos, led by future Major League manager Davey Johnson, were in first place with a 51–21 mark (.708) when the Inter-American League shut down.
