The IWA is probably the fastest growing promotion in Puerto Rico of the past few years. In recent years, it has given the island's long-standing promotion World Wrestling Council a tough competition, featuring younger local and international stars.
This promotion should not be confused with another IWA, which was started up by Eddie Einhorn and operated in the mid-1970s. Einhorn's IWA was arguably the first concentrated effort to create a single, nationally-touring wrestling promotion, competing directly against the members of the National Wrestling Alliance.
