WrestleMania XXVI
Along with WrestleMania XXVI, a series of events grouped as "WrestleMania Week" were held in the week preceding the event. To begin promotion for the event in Glendale, a "Kick-off Party" was held at the Westgate City Center on March 19, which included appearances from WWE wrestlers, autograph signings and live entertainment along with a giant LED screen viewing of that night's episode of "SmackDown". The third annual "WrestleMania Art" (formerly "WrestleManiArt"), an art exhibition and auction featuring work by WWE superstars, was held on March 24 at the Make-A-Wish Foundation National Headquarters. WrestleMania's annual fan convention, WrestleMania Axxess, was held from March 25 through March 28 at the Phoenix Convention Center. On March 27, WWE hosted its annual WWE Hall of Fame ceremony at the Dodge Theater, where the Class of 2010 were inducted.
WrestleMania XXVII
WrestleMania XXVII was a joint-promotion event, with performers from both the Raw and SmackDown brands. This would be the last joint-promotion WrestleMania until WrestleMania 33 in 2017; the first brand split ended in August 2011, meaning that performers were no longer exclusive to a brand, but the brand split returned in mid-2016. The event's card consisted of eight matches, including three main matches. In the first, Edge defeated Alberto Del Rio to retain the World Heavyweight Championship in what turned out to be Edge's final televised match before his retirement one week later due to cervical spinal stenosis in his neck. The second saw The Undertaker defeating Triple H in a No Holds Barred match to extend his undefeated WrestleMania streak to 19-0. The third saw The Miz defeating John Cena to retain the WWE Championship. This is the only WrestleMania where no championships changed hands; three championships were defended at the event and all three were retained.
