National Wrestling Association

The National Wrestling Association (NWA) was an early professional wrestling sanctioning body created in 1930 by the National Boxing Association (NBA; now the World Boxing Association, WBA) as an attempt to create a governing body for professional wrestling in the United States. The group created a number of "World" level championships as an attempt to clear up the professional wrestling rankings which at the time saw a number of different championships promoted as the "true world champion". The National Wrestling Association's NWA World Heavyweight Championship was later considered part of the historical lineage of the National Wrestling Alliance's NWA World Heavyweight Championship when then National Wrestling Association champion Lou Thesz won the National Wrestling Alliance championship, folding the original championship into one title in 1949.

With the creation of the National Wrestling Alliance and Thesz winning the Alliance's world title, the National Wrestling Association would officially recognize the champions of the National Wrestling Alliance at their annual conventions but no longer promote their own separate championships. The governing body would continue to hold conventions through at least the 1960s and officially disband in September 1980 but had no significant impact on professional wrestling past 1949.
