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.
WWE United States Championship
The inaugural champion was Harley Race. There have been 92 different champions, with Ric Flair having the most reigns at six. The longest-reigning champion was Lex Luger who held the title for 523 days from May 22, 1989, to October 27, 1990. The shortest-reigning champion was "Stunning" Steve Austin who held the title for approximately five minutes. Dean Ambrose is the longest-reigning champion under the WWE banner at 351 days from May 19, 2013, to May 5, 2014. Booker T and Seth Rollins are the only two men to have held both the United States Championship and a world championship simultaneously; in Booker T's case, the world title was the WCW World Heavyweight Championship, while Rollins held the WWE World Heavyweight Championship. (Both Lex Luger and Goldberg were the United States Champion when they won their first world championship, but unlike Booker T and Rollins, they vacated the United States Championship after winning their world championships.) Terry Funk is the oldest champion in the title's history, winning the title at the age of 56 on September 22, 2000, while David Flair is the youngest at the age of 20 on July 5, 1999.
