Amateur Athletic Union

The Amateur Athletic Union (AAU) is a nonprofit, volunteer-based organization in the United States dedicated to the promotion and development of amateur sports and physical fitness programs.

History

The AAU was founded on January 21, 1888, by James E. Sullivan and William Buckingham Curtis with the goal of establishing common standards in amateur sports[1]. Initially, it served as a leader in international sport and represented the United States in international sports federations. The AAU worked closely with the Olympic movement to prepare athletes for the Olympic Games[1].

Programs and Events

The AAU offers programs in over 45 sports and hosts numerous national championships, including the AAU Junior Olympic Games, one of the largest multi-sport events in the country[2]. It also organizes the AAU Junior National Volleyball Championships, the largest volleyball event in the world[2]. The AAU James E. Sullivan Award is presented annually to recognize the outstanding athlete in the U.S. at the collegiate, Olympic, or similar elite levels[4].

Mission and Philosophy

The AAU's philosophy is "Sports for All, Forever," aiming to provide opportunities for athletes of all ages and backgrounds to engage in sports[2]. Its mission emphasizes the development of athletes through good sportsmanship and citizenship[2].

Membership and Structure

The AAU has over 900,000 members and is structured into 55 distinct district associations across the U.S.[1]. It relies heavily on volunteer support, with more than 100,000 volunteers involved nationwide[1].

Transition and Focus

Following the Olympic Sports Act of 1978, the AAU shifted its focus from governing the U.S. Olympic sports teams to providing grassroots-level sports programs for all participants[1]. This transition allowed the AAU to maintain its relevance by focusing on youth development and community involvement[1].
