AAU Mr contests were to find the best representative of the ideal male. Judging included physique, athletic abilities, facial appearance, and personality. Therefore often the people with the best physiques did not win. Other orgs (including the relatively new IFBB (1964 was the first time the IFBB was not just two guys promoting shows), that only judged on muscle were becoming more popular. Some people in the AAU felt they needed to adapt with the times, others did not. A bunch of guys broke away and formed the NPC. There was a court case. Both sides won and lost. Ten plus years later the AAU tried to become a drug tested org, but kept getting sued by people who failed the drug tests, and finally in 1999 the AAU washed its hands of bodybuilding.
