With the emergence of trios (tag teams consisting of three people) such as "Los Misioneros de la Muerte", "Los Brazos" and more, the six-man tag team match became increasingly popular in the early 1980s. Its popularity led to the trios format becoming the most prevalent match format in "Lucha libre" to this day. The popularity led to the creation of the first trios championship in Mexico when the Universal Wrestling Association (UWA) created the UWA World Trios Championship in 1984. The Mexican National Trios Championship was created in 1985, at the request of Empresa Mexicana de Lucha Libre (EMLL) and endorsed by the Mexico City Boxing and Wrestling Commission. The commission granted EMLL the rights to promote the championship, which meant that CMLL had control over the everyday use of the championship, determining which storylines the title wre being used in, who were allowed to challenge for the title and how to use it in a public relations sense. The Commission would oversee the rule and approves any championship change that EMLL proposed.
