, who won the title as the AEW All-Atlantic Championship|left The
professional wrestling championship was unveiled by the American promotion
All Elite Wrestling (AEW) on its television program
Dynamite on June 8, 2022. It was originally established as the AEW All-Atlantic Championship and was created to be a secondary title for the men's division. Despite its original name seemingly centering on countries around the
Atlantic Ocean, the company said that the championship represented AEW's fans from around the world. The inaugural champion was crowned in a
four-way match which was held at the
Forbidden Door pay-per-view event on June 26, which was co-produced with the
Japanese promotion
New Japan Pro-Wrestling (NJPW). To determine the competitors in the four-way, six qualifying matches were held. Three of these featured wrestlers from AEW with the three winners advancing to the four-way match. On the AEW side,
Pac,
Miro, and
Malakai Black won their qualifiers; on the NJPW side,
Tomohiro Ishii qualified but suffered a legitimate left knee injury and had to be replaced with the runner-up,
Clark Connors. At Forbidden Door, Pac became the inaugural champion by submitting Connors. ; his first reign is also the longest reign at 326 days and he has the longest combined reign at 471 days.

Tony Khan confirmed that the championship would be defended differently than the company's other titles. Khan said that holders of the championship would defend the title internationally in other promotions, in addition to AEW. This interview came shortly after Pac defended the title at an event for Britain's
Revolution Pro Wrestling (RevPro), which was later shown on AEW's
YouTube show,
Dark, on July 12. Pac also defended the title at an event for Ireland's
Over the Top Wrestling (OTT) on July 22. Since then, the title has been defended in NJPW, Mexico's
Consejo Mundial de Lucha Libre (CMLL), and Canada's
Maple Leaf Pro Wrestling (MLP). On the March 8, 2023, episode of
Dynamite, Tony Khan announced that
Orange Cassidy's defense of the title that night was the final as the AEW All-Atlantic Championship. The following week on March 15, in celebration of the release of the
Warner Bros. film
Shazam! Fury of the Gods, the title was rebranded as the AEW International Championship due to AEW's broadcast partnership with
Warner Bros. Discovery. At the time, AEW had considered this to be a new title, with Cassidy regarded as the final All-Atlantic Champion and inaugural International Champion, but the title history was later amended to show that it was the same championship with Cassidy's reign as one continuous reign from when he originally defeated Pac for the title. with his custom "American Championship" belt.|288x288px During
Dynamite: Blood & Guts on July 24, 2024, reigning champion
MJF, who won the title from
Will Ospreay at the previous week's
Dynamite 250, unofficially rebranded the title as the "AEW American Championship". He also introduced his own custom version of the title belt to reflect this unofficial name change. After Ospreay regained the title at
All In London the following month on August 25, the title was restored as the International Championship. At
Revolution on March 9, 2025,
Kenny Omega dethroned
Konosuke Takeshita to win the International Championship. After successfully defending the title at
Dynamite: Fyter Fest on June 4, 2025, Omega was confronted by
AEW Continental Champion Kazuchika Okada, setting up a
Winner Takes All match for
All In on July 12. A week later during the contract signing at
Dynamite: Summer Blockbuster,
Tony Schiavone announced that the winner would also
unify the International and Continental titles as the
AEW Unified Championship. During the All In: Texas media call just a few days prior to the event on July 8, Tony 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 had the option to carry around all three belts. At All In, Okada defeated Omega to become the Unified Champion. 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, thus ending the unification and forcing Okada to relinquish the Unified Championship.
