AWA World Heavyweight Championship (Boston version)

[1] The title was created by Bowser after Gus Sonnenberg, who had beaten Ed Lewis for the original World Heavyweight Wrestling Championship in 1929,[2] was stripped of recognition as champion by the National Boxing Association.

Browser continued to recognize Sonnenberg as champion and named his championship after the "American Wrestling Association" governing body, which hitherto did not actually exist.

[3] Rival promoters, including Jack Curley, countered by forming the National Wrestling Association and its NWA World Heavyweight Championship.

[4] During Don Eagle's second reign, splinter titles were created by regional promoters in Chicago and Ohio.

Bowser abandoned the championship later in Eagle's reign, while he was rendered inactive due to injuries in November 1952.
