Equestrian Events, Inc. is a non-profit Kentucky corporation formed in 1975 initially to stage the 1978 World Three-Day Event Championships at the brand new Kentucky Horse Park, in Lexington, Ky. In October 1976, as preparation for the World Championships, EEI organized the first horse trials ever held at the Horse Park. In 1977, the organization coordinated the staging of the National Pony Club Rally in August and produced the North American Junior Three-Day Event Championships in September.
EEI went on to organize the 1978 World Three-Day Event Championships, held for the first time in the United States, which were an unprecedented success. Shortly after the conclusion of the World Championships, the American Horse Shows Association asked EEI to host the first major three-day event of the new year, setting the wheels in motion for the 1979 Kentucky Horse Trials and similar events thereafter.
Equestrian Events, Incorporated is a non-profit, charitable organization that supports the development of riders and horses in one or more of the sports recognized by the Fédération Equestre Internationale (FEI). Through the staging of an annual event at the highest level, EEI seeks to ensure the competitiveness of the United States in international competition, and to enhance the equine industry worldwide.
