The NWA World Historic Light Heavyweight Championship (Campeonato Mundial Historico de Peso Semicompleto de la NWA in Spanish) is a professional wrestling championship promoted by Consejo Mundial de Lucha Libre (CMLL). CMLL had held the NWA World Light Heavyweight Championship for over 48 years, when the relationship between the promotion and National Wrestling Alliance broke down in March 2010. Blue Demon Jr., the president of NWA Mexico, sent letters to CMLL, telling them to stop promoting the NWA-branded championships since they were no longer part of the NWA. On August 12, 2010, CMLL debuted the new NWA World Historic Light Heavyweight Championship belt and named El Texano Jr., the final CMLL-recognized NWA World Light Heavyweight Champion, as the inaugural champion.
