WWF Light Heavyweight Championship: The WWF Light Heavyweight Championship was a professional wrestling championship in the World Wrestling Federation (WWF, now WWE) promotion.  The title was challenged by light heavyweights at a maximum weight of 215 lbs (before deactivation, the weight limit was changed to 220Ibs).  It was created on March 26, 1981 for the Universal Wrestling Association (UWA) in a partnership between the WWF and UWA.  In 1995, the title moved to New Japan Pro Wrestling, but due to WWF's ownership of the title, it was returned to the WWF in 1997, the year in which the WWE begins the championship's lineage.  The inaugural champion in UWA was Perro Aguayo, however, the WWE considers the inaugural champion to be Taka Michinoku, with his reign beginning on December 7, 1997.  It was retired in November 2001 with X-Pac as the final champion.

WNC Championship: The WNC Championship was a professional wrestling championship owned by the Wrestling New Classic (WNC) promotion.  The title was a spiritual successor to the Smash Championship, the top title of WNC's predecessor, Smash.  The championship was first announced at a press conference on September 28, 2012, when it was announced that a single-elimination tournament to determine the inaugural champion would take place from October 26 to December 27.  In storyline, the championship belt was donated to WNC by the final Smash Champion and WWE road agent Dave Finlay, who was also named the head of the WNC Championship Committee, which decides matches for the title.

NWA World Historic Welterweight Championship: The NWA World Historic Welterweight Championship ("Campeonato Mundial Historico de Peso Welter de la NWA" in Spanish) is a professional wrestling championship governed by Consejo Mundial de Lucha Libre (CMLL).  CMLL had held the NWA World Welterweight Championship for over 53 years even after leaving the NWA in 1989.  In 2010 the National Wrestling Alliance, represented by Blue Demon Jr., the president of NWA Mexico, sent letters to CMLL telling them to stop promoting NWA-branded championships since CMLL was not part of the NWA any longer.  On August 12, 2010, CMLL debuted the new NWA World Historic Welterweight Championship belt and named Mephisto, the final CMLL-recognized NWA World Welterweight Champion, as the inaugural champion.  The championship was initially announced as the CMLL Historic Welterweight Championship, but when the belt was unveiled, it was labelled the "NWA World Historic Welterweight Championship".

The title is often referred to simply as the "White Belt", a name famously used by All Japan Women's Pro-Wrestling (AJW) to refer to its All Pacific Championship.  The title belt was crafted by American company Top Rope Belts based on designs sent by Stardom, with a conscious decision to imitate the AJW title belt in terms of its color, with Stardom president Rossy Ogawa referring to the promotion's heyday as the "Golden Age of "Joshi Puroresu"".  The original title belt was awarded to undefeated inaugural champion Yuzuki Aikawa, when she retired from professional wrestling on April 29, 2013.  It was replaced that same night by a second identical title belt.

After then-WWE Divas Champion Maryse was drafted to Raw as part of the 2009 WWE draft, she took the title with her.  McCool won a match against Melina to unify the WWE Divas and Women's titles at the Night of Champions pay-per-view on September 19, 2010, creating the Unified WWE Divas Championship; it eventually dropped the "Unified" moniker.

WWE Hardcore Championship: The WWE Hardcore Championship was a hardcore wrestling championship in WWE (formerly the World Wrestling Federation), which was contested under "hardcore" rules (no disqualifications, no countouts, and pinfalls count anywhere).
