NWA World Historic Middleweight Championship

The NWA World Historic Middleweight Championship (Campeonato Mundial Historico de Peso Medio de la NWA in Spanish) is a professional wrestling championship promoted by Consejo Mundial de Lucha Libre (CMLL). The official definition of the middleweight weight class in Mexico is between 82 kg and 87 kg, but is not always strictly enforced. For example, previous NWA World Historic Middleweight Champion Último Guerrero is billed as weighing 95 kg. Místico is the current champion, he is the eighth champion overall and he is in his first reign.

For over 62 years CMLL controlled the NWA World Middleweight Championship, even after leaving the National Wrestling Alliance (NWA) in the late 1980s. Up until 2010 the NWA more or less ignored CMLL's use of the championship, but in March 2010 Blue Demon Jr., the president of the newly formed NWA Mexico, sent letters to CMLL, demanding that they stop promoting the NWA-branded championships since they were not part of the organization. NWA Mexico had previously tried to reclaim the three NWA-branded championships promoted by CMLL, but was ignored by CMLL. Finally, on August 12, 2010, CMLL debuted the new NWA World Historic Middleweight Championship belt and named Averno, the final CMLL-recognized NWA World Middleweight Champion, as the inaugural champion.

Background
In 1933 the Mexican National Middleweight Championship was introduced as Yaqui Joe won it in a tournament. The same year Salvador Lutteroth founded Empresa Mexicana de Lucha Libre (EMLL; "Mexican Wrestling Enterprise") and would later be allowed to host matches for the Mexican National Middleweight Championship although they did not have exclusive rights to the championship.

In either late-1938 or early-1939 Lutteroth and EMLL declared that Gus Kallio, due to holding the National Wrestling Association World Middleweight Championship was also recognized as the World Middleweight Champion in Mexico. On February 19, 1939 Kallio lost the championship to EMLL wrestler Octavio Gaona, to create EMLL's main championship for the middleweight division. In 1952 EMLL joined the National Wrestling Alliance (NWA) and the middleweight championship was rebranded as the NWA World Middleweight Championship from that point forward. In 1989 EMLL left the NWA because the promoters did not want to deal with the internal politics of the NWA at the time. While they left the NWA they kept promoting the NWA World Middleweight Championship as well as the NWA World Light Heavyweight Championship and the NWA World Welterweight Championship that they had controlled for years.

In 1991. EMLL changed their name to "Consejo Mundial de Lucha Libre" (CMLL; "World Wrestling Council") and began to introduce a number of CMLL branded championships. On December 18, 1991, Blue Panther won the CMLL World Middleweight Championship in a tournament, giving CMLL control of three different middleweight championships at the time. In 1992, then-CMLL promoter Antonio Peña left CMLL along with a number of CMLL wrestlers, and founded rival promotion Asistencia Asesoría y Administración, later known simply as AAA. One of the wrestlers that left CMLL was Octagón, who was the reigning Mexican National Middleweight Champion. The Mexico City Boxing and Wrestling Commission granted AAA the rights to promote the Mexican National Middleweight Championship from that point on.

On December 4, 1993, Corazón de León won the NWA World Middleweight Championship on a CMLL show and then took the title with him when he began working in Japan. On November 8, 1994, Último Dragón won the championship and for the next 10 years the title was promoted primarily in Japan. On September 3, 2004, Averno defeated Zumbido to win the vacant championship, bringing it back under CMLL's control.

In March 2010, Blue Demon Jr., the president of the newly formed NWA Mexico, reached out to CMLL, demanding that they stop promoting the NWA-branded championships since they were not part of the NWA. While the NWA had previously tried to reclaim the three NWA-branded championships promoted by CMLL, those requests were ignored by CMLL. The promotion did not directly respond to the latest request either; instead the then-NWA Welterweight Champion, Mephisto, commented on the situation, simply stating that the titles belonged to CMLL. Finally, on August 12, 2010, CMLL announced that they were replacing the NWA World Middleweight Championship with the CMLL World Historic Middleweight Championship and named Averno, the final CMLL-recognized NWA World Middleweight Champion, as the inaugural champion. When Averno made his first appearance with the championship it had been rebranded as the "NWA World Historic Middleweight Championship" (Campeonato Mundial Historico de Peso Medio de la NWA in Spanish).

Reigns
Místico is the current NWA World Historic Middleweight Champion, having defeated the previous champion, Ultimo Guerrero, on August 21, 2018 in Guadalajara, Jalisco, Mexico. Caristico is the eighth overall champion, with no wrestler holding the championship more than once so far. The championship has not been declared vacant since its creation in 2010 and has been defended in both Mexico and in Japan. Volador Jr. was the shortest reigning champion, holding the title for 45 days in early 2012, while La Sombra currently holds the record for the longest reign, 953 days or over two-and-a-half years. When La Sombra defeated Dragón Rojo Jr. to win the championship during the Fantastica Mania 2013 show in Bunkyo, Tokyo, it marked the first time the championship changed hands outside of Mexico.

With his victory on August 31, 2015, Último Guerrero became the oldest wrestler to win the championship, being 43 years, 183 days old, while La Sombra was the youngest wrestler to win the championship, 23 years, 78 days old. At an official weight of 79 kg Averno is the lightest wrestler to hold the championship, while Último Guerrero, at 93 kg, is the heaviest champion.

Rules
The championship, being a professional wrestling championship, is not won legitimately: it is instead won via a scripted ending to a wrestling match. The official definition of the middleweight weight class in Mexico is between 82 kg and 87 kg, but is not always strictly enforced. For example, the previous NWA World Historic Middleweight Champion Último Guerrero is billed as weighing 93 kg, significantly above the official weight limit. All championship matches held in Mexico take place under best two-out-of-three-falls rules, while championship matches held in Japan normally conform to the one fall rule that is customary in Japanese wrestling.
