WrestleMania 13 was the thirteenth annual WrestleMania professional wrestling pay-per-view event produced by the World Wrestling Federation (WWF). The event was held on March 23, 1997 at the Rosemont Horizon in the Chicago suburb of Rosemont, Illinois.
The main event was a no disqualification match between The Undertaker and Sycho Sid for the WWF Championship, which Undertaker won following interference from Bret Hart. The main matches on the undercard were Bret Hart versus Steve Austin in a submission match, Legion of Doom and Ahmed Johnson versus Nation of Domination in a Chicago Street Fight and Hunter Hearst Helmsley versus Goldust.
Steve Austin and Bret Hart continued their rivalry after WrestleMania, but Austin was now a babyface while Hart was a heel. Hart recruited British Bulldog, Owen Hart, Brian Pillman and former tag team partner Jim Neidhart to reform The Hart Foundation. At Revenge of the 'Taker, Hart and Austin had a match which Austin won by disqualification. Their feud continued until Canadian Stampede, where Canadian Hart Foundation defeated American team of Austin, Ken Shamrock, Legion of Doom (Hawk and Animal) and Goldust.
The Undertaker got a push after he won his second WWF Championship at WrestleMania 13. He spent a reign of 133 days which included battles with Mankind, Steve Austin, Faarooq and Vader. At SummerSlam 1997, Undertaker's long reign finally ended when he lost the title to Bret Hart when special guest referee Shawn Michaels accidentally struck Undertaker with a steel chair, which was intended for Hart.
