In the late 1980s, EMLL left the NWA over internal politics, and by 1991 they had changed their name to Consejo Mundial de Lucha Libre ("World Wrestling Council"; CMLL) to distance themselves from the NWA. At first, they continued to use the name "NWA World Middleweight Championship" as the name had originated with EMLL, but they soon created a series of CMLL-branded world championships, including the CMLL World Middleweight Championship, which became the third middleweight championship in the company. CMLL held a one-night, eight-man tournament to determine the first middleweight champion on December 18, 1991. The tournament final saw Blue Panther defeat El Satánico to become the first new titleholder.
