WrestleMania 31

WrestleMania 31 was a 2015 professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was the 31st annual WrestleMania and took place on March 29, 2015, at Levi's Stadium in the San Francisco Bay Area city of Santa Clara, California. This was the last WrestleMania to be held in March, as all WrestleMania events since have been held in April.

Nine matches were contested at the event, including two matches on the Kickoff pre-show. In the main event, Seth Rollins cashed in his Money in the Bank contract as the scheduled match between defending champion Brock Lesnar and Roman Reigns was in progress, and won the resulting impromptu triple threat match to win the WWE World Heavyweight Championship. In other prominent matches, The Undertaker (in his first on-screen appearance since the previous year's event) defeated Bray Wyatt and John Cena defeated Rusev to win the WWE United States Championship. The event was also notable for Sting's debut match in WWE, as well as his only WrestleMania match, in which he was defeated by Triple H.

Despite criticism for its build-up, WrestleMania 31 received highly positive reviews from fans and critics; some critics called it one of the greatest WrestleManias of all time. Praise was directed to the quality of matches, the conclusion to the main event and focused match card, although the women's tag team match was subject to criticism for being seen as "filler" and Triple H's win over Sting was criticised as an unnecessary ode to WWE winning the Monday Night War. WWE reported that the show was the highest grossing WWE event ever, drawing a revenue of $12.6 million. The company also claimed an attendance figure of 76,976. This was also the first WrestleMania to incorporate WWE's current logo that was originally used for the WWE Network.
