List of WWF Light Heavyweight Champions: The WWF Light Heavyweight Championship was a professional wrestling cruiserweight championship operated by the World Wrestling Federation (WWF).  Only wrestlers that weighed less than 220 lb , called light heavyweights in professional wrestling, were allowed to challenge for the title.  From 1981 through the 1990s, the WWF had a business partnership with the Universal Wrestling Association (UWA), a Mexican lucha libre-based promotion, which resulted in the creation of the WWF Light Heavyweight Championship for the UWA.  When the UWA ceased operations in 1995, the title traveled to the Japanese New Japan Pro Wrestling (NJPW) promotion.  In 1997, as a result of the WWF owning the trademarks to the championship, NJPW was forced to return the title to the WWF.  One month later, the WWF began operating the title in the United States.  World Championship Wrestling (WCW) and its assets were acquired by the WWF in March 2001, which included the copyrights to their championships.  The WCW Cruiserweight Championship, a counterpart to the Light Heavyweight Championship, was one of these titles.  After acquiring WCW, the WWF used the Cruiserweight Title, among other WCW championships, during The Invasion storyline, which featured former WCW wrestlers feuding with original WWF wrestlers before WCW's purchase.  After The Invasion narrative ended in December 2001, the WWF replaced the Light Heavyweight Title with the Cruiserweight Championship, which had the WWF acronym added to its name.  World Wrestling Entertainment (WWE), the successor of the WWF, operated the Cruiserweight Championship until 2007, when the title was deactivated.
