In 2018, MMWA’s Tony Casta, SICW’s Herb Simmons, and New Breed Wrestling’s Scott Zei founded this inter-promotional tag team title, originally known as the Multi-State Tag Team Championship. Impact Pro (Iowa) and 3XW (Iowa) joined the agreement thereafter.
After the death of Tony Casta and SICW’s establishment of their own tag title, the Multi-State title de facto became New Breed Wrestling’s property. The name change was formalized in May 2021.
The champions can defend the title at any of the companies’ events.
