In 1984, the United Quarab Registry (UQR) was formed as the breed association for Quarter Horse/Arabian crossbred horses. In 1989, a new section of the registry, called the Painted Quarab Index, was added to include horses with blood from the American Paint Horse that showed tobiano and overo color patterns. The UQR was privately owned and later went out of business after a change of ownership. In 1999 the International Quarab Horse Association was formed to register the breed, functioning under the same guidelines as the UQR and soon spreading overseas, with member groups in Germany and the Netherlands.
