As the popularity of the AAU Youth Sports Program increased, the AAU leaders decided to conduct two national championships simultaneously. The idea came to fruition when Vice-President Hubert H. Humphrey proclaimed the first AAU Junior Olympic Games open on August 21, 1967, in downtown Washington, D.C., at the Departmental Auditorium on Constitution Avenue. Five hundred twenty-three athletes competed in the inaugural AAU Junior Olympic Games that year. National champions were determined in swimming and track and field. Eighteen AAU records in swimming and three in track and field were established.
