The Ara­bi­an Horse Asso­ci­a­tion (AHA) is the sin­gle nation­al orga­ni­za­tion that is the only breed reg­istry that reg­is­ters Ara­bi­an hors­es in the Unit­ed States. It also works with the Unit­ed States Eques­tri­an Fed­er­a­tion to sanc­tion horse shows and license judges for Ara­bi­an hors­es. The AHA was formed by a merg­er between the Inter­na­tion­al Ara­bi­an Horse Asso­ci­a­tion (IAHA) and the Ara­bi­an Horse Reg­istry of Amer­i­ca (AHRA) in 2003. AHRA was the old­er of the two orga­ni­za­tions, a breed reg­istry found­ed in 1908. IAHA, found­ed in 1950, orga­nized to “meet the breed­ing, com­pet­i­tive and recre­ation­al inter­ests of all Ara­bi­an horse own­ers,” and also main­tained a Half-Ara­bi­an and Anglo-Ara­bi­an registry.
