Mexican National Welterweight Championship
The Mexican National Welterweight Championship is a Mexican professional wrestling championship created and sanctioned by Comisión de Box y Lucha Libre Mexico D.F.. While the commission sanctions the title, it does not promote the events at which the title is defended. Consejo Mundial de Lucha Libre promotes the events and has the everyday control of the championship. The official definition of the welterweight weight class in Mexico is between and, but is not always strictly enforced. Because Lucha Libre emphasizes the lower weight classes, this division is considered more important than the normally more prestigious heavyweight division of a promotion. As it is a professional wrestling championship, it is not won legitimately; it is instead won via a scripted ending to a match or awarded to a wrestler because of a storyline. All title matches take place under two out of three falls rules.
The championship was created on June 17, 1934, making it the oldest professional wrestling championship still promoted. Documentation is unclear on the details of the tournament other than that Mario Nuñez won the title by defeating Tony Canales in the final on June 17, 1934. In the early days of the championship no single professional wrestling promotion had exclusive control of the championship, but as Empresa Mexicana de Lucha Libre became dominant it became the main promoter of the championship, with the Commission pre-approving the champions. After El Felino vacated the title in 1992, control of the championship was granted to Asistencia Asesoría y Administración, which promoted the title for the next six years. In 1998 control of the Welterweight Championship was returned to CMLL when Arkangel de la Muerte defeated El Toreo on a CMLL show. Since then the title has been promoted exclusively by CMLL.
Karloff Lagarde holds all "longevity" records for the championship. He has had the longest individual reign, the longest combined reign and the most reigns of any champion, with four. Psicosis holds the record for the shortest reign, having held the title for only two days. Soberano Jr. is the current champion, having defeated Rey Cometa on May 12, 2017, to win the championship. It is Soberano Jr.'s first Welterweight Championship reign and first championship reign of any kind, he is the 75th overall champion and the 56th person to hold the title.
