The event is a revival of the Professional Wrestling Opera House Cup, which had been last held in 1948.
MLW hosted their first edition in 2019 and it has since become a recurring event for the promotion.
Opera House Cup was annually held as a professional wrestling tournament for nearly fifty years in various cities in the United States until 1948, when Stu Hart won the tournament and it was discontinued.
On July 21, 2019, Major League Wrestling announced that it would be holding an event on December 5 at the Melrose Ballroom in Queens, New York City, New York which would be a set of television tapings for MLW Fusion.
