On the March 20, 2024, episode of the
professional wrestling promotion
All Elite Wrestling's (AEW) flagship television program,
Dynamite,
Kazuchika Okada won the
AEW Continental Championship. The following year on March 9, 2025, at the
Revolution pay-per-view (PPV) event,
Kenny Omega won the
AEW International Championship. Over this time, AEW began teasing a match between the two to reignite a long rivalry between them from their time in
New Japan Pro-Wrestling (NJPW). This came to a head at
Dynamite: Fyter Fest on June 4, where Okada confronted Omega to set up a
Winner Takes All match at
AEW All In: Texas. During the contract signing at
Dynamite: Summer Blockbuster,
Tony Schiavone announced that the match would unify the Continental and International titles as the AEW Unified Championship. Okada would go on to defeat Omega to become the inaugural Unified Champion. Since Okada won as the Continental Champion, AEW president
Tony Khan confirmed that the Unified Championship would be contested under Continental Rules, the same rules for matches for the Continental Championship, in which no one is allowed at ringside, outside interference is strictly prohibited, and matches have a 20-minute time limit. AEW stated that the title would be booked as another top championship on par with the
AEW World Championship and not as a "
mid or upper-midcard level title". During the All In: Texas media call on July 8, Khan clarified that neither the Continental or International Championships would be retired, and that their lineages would still be intact along with a new lineage for the Unified Championship, and the champion can choose to carry all three championship belts. Khan stated that the Unified Championship was established because, "I wanted to create something special around this match and event". Okada defended the three belts as one between All In and the
2025 Continental Classic. The tournament itself was only for the Continental Championship, meaning if Okada lost, he would also have to vacate the Unified Championship. In the final of the Continental Classic at
Worlds End on December 27, 2025, Okada lost to
Jon Moxley, forcing him to relinquish the Unified Championship, rendering it inactive. ==Belt design==
