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.

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.

Blue Demon Jr. was in the process of establishing NWA Mexico as a promotion and wanted to use the championship.

The promotion did not directly respond to the latest claim; the NWA Welterweight Champion, Mephisto, commented instead, simply stating that the championships belonged to CMLL.

[10] Finally, 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.

[11][12] The first champion, El Texano Jr., held the title for the shortest reign between August and December 2010, a total of 124 days.

[20][22] While the heavyweight championship is traditionally considered the most prestigious weight division in professional wrestling, CMLL places more emphasis on the lower weight divisions, often promoting those ahead of the CMLL World Heavyweight Championship.

[24][25] The following week, on June 21, Rey Bucanero defeated El Hijo del Fantasma to become the third ever NWA World Historic Light Heavyweight Champion.

La Sombra and Rey Bucanero outlasted Atlantis, Blue Panther, Dragón Rojo Jr., Ephesto, Misterioso Jr., Mr. Águila, Niebla Roja, Stuka Jr., Valiente and Último Guerrero in a 12-man torneo cibernetico elimination match.
