National Boxing Association
Formed 1921 in Rhode Island, USA, the National Boxing Association (NBA) became the World Boxing Association (WBA) in 1962. It is not to be confused with the current National Boxing Association, a completely new and different body.
1921-01-13: The newly-founded NBA is composed of 17 American states. Tacoma News Tribune (Tacoma, WA, USA) wire report. (By late 1948, New York and Massachussetts were the only states where boxing was conducted which were not members of the NBA.)
