NWA World Middleweight Championship The NWA World Middleweight Championship is a currently inactive professional wrestling championship , promoted by the National Wrestling Alliance ( NWA ) . For the majority of its existence it has been promoted by Mexican promotion Consejo Mundial de Lucha Libre ( CMLL ) , where it was known as the " Campeonato Mundial Peso Medio de NWA " . The title , being a professional wrestling championship , it is not won legitimately : it is instead won via a scripted ending to a wrestling match . The official definition of the middleweight weight class in Mexico is between 82 kg ( 180 lbs ) and 87 kg ( 190 lbs ) , but is not always strictly enforced . The Championship was originally called the " World Middleweight Championship " , and was created by Salvador Lutteroth , owner of Empresa Mexicana de Lucha Libre ( EMLL ) . Lutteroth awarded the title to Gus Kallio , a five - time National Wrestling Association World Middleweight Champion and the " king of the middleweights " in the United States . The title was created at an unknown point before March 29 , 1939 . When Octavio Gaona defeated Kallio on March 29 , 1939 he also won Kallio ' s other World Middleweight Championship . Kallio ' s original world middleweight title was retired in 1940 to keep the focus on the Mexican version of the championship . When EMLL became a member of the National Wrestling Alliance ( NWA ) in 1952 the belt was given the " NWA " prefix . In the early 1990s EMLL withdrew from the NWA and changed their name to Consejo Mundial de Lucha Libre in order to create a clean break from their past NWA association . While they withdrew from the NWA , they retained the ownership of three NWA - labelled championships that all originated in EMLL . The other two titles were the NWA World Welterweight Championship and the NWA World Light Heavyweight Championship . The titles are still promoted as " NWA Championships " by CMLL despite not being officially recognized by the NWA since the early 1990s . In 1994 Último Dragón paid CMLL for the rights to the NWA World Middleweight Championship , giving him control of the Championship . Dragón won the title from Corazón de León on November 8 , 1994 , after which he began promoting the belt in Japan ; where it and the title remained in Japan for almost ten years . In 2003 Último Dragón signed with World Wrestling Entertainment and sold the title back to CMLL . Averno defeated Zumbido to win the vacant title in the first CMLL - based title match since 1994 . 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 not part of the NWA . NWA Mexico has previously tried to reclaim the three NWA - branded championships promoted by CMLL , but was ignored by CMLL . The promotion did not directly respond to the latest claim either ; the NWA Welterweight Champion , Mephisto , commented , simply stating that the titles belonged to CMLL . Finally , on August 12 , 2010 , CMLL debuted the new NWA World Historic Middleweight Championship and returned the old belt to NWA . NWA has not determined a new champion since getting the title back from CMLL . There have been 84 reigns between 45 different wrestlers . René Guajardo has held the championship on six separate occasions , the most by any wrestler . Tarzán López ' s four reigns combine for 2 , 977 days , the longest of any champion , while the Great Sasuke ' s single reign is the longest individual reign with 1 , 487 days . Oro is the person who has held the title the shortest time , 41 days .
