The title started in 1968 as a National Wrestling Alliance title, named the NWA North American Heavyweight Championship (Buffalo/Cleveland version) until the NWF was founded in 1970. It was then renamed with the NWF name. The NWF would close in 1974, and the title migrated to New Japan Pro Wrestling. The title was then abandoned in 1981.
