Only wrestlers that weighed less than 220 pounds (100 kg), called "light heavyweights" by the WWF, 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-based lucha libre 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 promotions Michinoku Pro Wrestling (MPW) and New Japan Pro-Wrestling (NJPW).
The first champion to be recognized by the UWA and NJPW was Perro Aguayo, who won the title in a tournament final in March 1981.
The first champion recognized by the WWF was Taka Michinoku, who won the title in a tournament final on December 7, 1997.
