NWA Mexico is a Lucha Libre promotion based out of Mexico City, Mexico. In March 2010 Blue Demon Jr., the president of NWA Mexico, sent letters to CMLL, telling them to stop promoting the NWA branded championships (NWA World Welterweight Championship, NWA World Middleweight Championship, and NWA World Light Heavyweight Championship) since they were no longer part of the NWA. NWA Mexico had previously tried to reclaim the three NWA branded championships promoted by CMLL but were ignored. On August 12, 2010, CMLL debuted the new NWA World Historic Welterweight Championship, NWA World Historic Middleweight Championship and NWA World Historic Light Heavyweight Championship to avoid anymore trouble from NWA Mexico. NWA Mexico created two new championships of their own (see below).
