The Mexican National Trios Championship is a three-man tag team professional wrestling championship, sanctioned by the "Comisión de Box y Lucha Libre Mexico D.F.", which oversees all matches where the championship is defended. Since its creation in 1985 the championship has been promoted by several major Mexican wrestling promotions, Empresa Mexicana de Lucha Libre (EMLL), Asistencia Asesoría y Administración (AAA) and is currently promoted by Consejo Mundial de Lucha Libre. The change from promotion to promotion was approved by the commission if the trios champions left one promotion to work for the other. As it is a professional wrestling championship, it is not won or lost competitively, but instead by the decision of the bookers of a wrestling promotion. The title is awarded to a team after the team "wins" a match to maintain the illusion that professional wrestling is a competitive sport. All title matches take place under two-out-of-three falls rules.

Arturo Díaz Mendoza was a Mexican professional wrestler who performed under the ring name Villano III. Díaz was a second-generation wrestler, son of luchador Ray Mendoza and the father of professional wrestlers Villano III Jr. and El Hijo del Villano III himself. All five of the Díaz brothers used the Villano name; José de Jesús, José Alfredo, Tomás and Raymundo. Of the five Villanos, Arturo was considered the most successful in terms of championship and Lucha de Apuesta wins as well as the most talented luchador in the family. He retired from wrestling in 2015 due to health issues stemming from wrestling. A few days after his death, he was inducted in the AAA Hall of Fame.
