On the June 8, 2021, episode of NWA Power, National Wrestling Alliance (NWA) president Billy Corgan announced a four-day block of NWA programming from Saturday, August 28 to Tuesday, August 31 that would emanate from the Khorassan Ballroom of the Chase Park Plaza in St. Louis, Missouri, marking the first event that the NWA has held outside of the state of Georgia since the 2019 Crockett Cup. The block consisted of two pay-per-view (PPV) events, which were broadcast exclusively on FITE TV, and two Power tapings. NWA 73 was announced as the Sunday PPV, celebrating the 73rd anniversary of the National Wrestling Alliance.[1][2] On August 28, the NWA released a video package on their YouTube page that would be used for the cold opening of the PPV event, celebrating the history of wrestling at The Chase, with narration provided by actor John Goodman.[3]
Women's wrestling veteran Mickie James, who was revealed as executive producer for the previous pay-per-view, EmPowerrr, revealed that she would be issuing an open challenge at the 73rd Anniversary Show.[4][5][6][7][8] Her opponent would be revealed on August 13 as Kylie Rae.[9]
On July 13 at an NWA press conference held at The Chase, James announced the NWA Women's Invitational; a tournament held on EmPowerr featuring the best up-and-coming female talent in the world, where the winner of the tournament would defend every year on NWA Anniversary weekend. She also announced that the winner of the tournament would earn an NWA World Women's Championship match at NWA 73.[10][11]
