The first champion was Yaqui Joe; records of the identity of his opponent for the championship are unclear. In early 2009, AAA stopped promoting all Mexican National Championships, opting to focus on its AAA-branded championships instead. In 2021, the championship was reactivated by Consejo Mundial de Lucha Libre, with Templario defeating Dragón Rojo Jr. to win the vacant title.
