The Florida Cracker Horse originated in Spain, but was brought over to Florida in the 1500's to be used as a cow horse. When the Spanish discovered Florida, they originally flooded the agriculture industry in the area with cattle and ranching. This little, gaited horse, was used for ranching, as the gait and size made the horse comfortable for riding over long distances.
The Spanish inevitably left horses behind, and the breed continued to evolve as a wild species. Today there are only 800 Florida Cracker Horses registered with the FCHA (website HERE), a registry that was founded in 1989.
