History of WWE
The two top stars of the Attitude Era, Stone Cold Steve Austin and The Rock, eventually left the company in 2003 and 2004 respectively, while newcomers such as Brock Lesnar, who would become the youngest WWE Champion and Randy Orton, who became the youngest World Heavyweight Champion, saw huge success. Triple H would also be featured prominently during this time, winning several of his fourteen world championships, as would The Undertaker whose WrestleMania win streak started gaining fame. Eddie Guerrero, Rey Mysterio, Kurt Angle, Chris Benoit, Edge, Brock Lesnar, Randy Orton, John Cena, Batista, John "Bradshaw" Layfield, and Rob Van Dam were also given main event opportunities and all ended up becoming multiple-time world champions. From mid 2002 to 2003, WWE brought several prominent WCW stars to the company, including Eric Bischoff, Scott Steiner, Goldberg, Kevin Nash and Ric Flair. The Great American Bash, originally a WCW pay-per-view event, made its debut in WWE.
Professional wrestling tournament
After CM Punk won the WWE Championship by defeating John Cena at WWE Money in the Bank and walked out of the company with the title, Vince McMahon set up a tournament to decide a new champion the following night on Raw. A week later in the final, Rey Mysterio defeated The Miz in the opening match of the broadcast to become WWE Champion. However, he would lose the title to Cena later that night, who would win the title for a WWE record ninth time. CM Punk then returned to the WWE with the title he won, meaning that for the first time in WWE history, two men had a claim to the title. The issue was settled at SummerSlam where Punk won a controversial rematch with Cena to become Undisputed Champion though he would lose the title to Raw Money In The Bank winner Alberto Del Rio seconds later.
