Andalusian horse
Both the Andalusian and the Percheron have Spanish and Barb ancestry. The Andalusian horse is descended from the Iberian horses of Spain and Portugal, and derives its name from its place of origin, the Spanish region of Andalusia. Throughout history, the Iberian breeds have been influenced by many different people and cultures who occupied Spain, including the Celts, the Carthaginians, the Romans, various Germanic tribes and the Moors. The Iberian horse was identified as a talented war horse as early as 450 BCE. Despite their ancient history, all living Andalusians trace to a small number of horses bred by religious orders in the 18th and 19th centuries. An influx of heavy horse blood beginning in the 16th century, resulted in the dilution of many of the bloodlines; only those protected by selective breeding remained intact to become the modern Andalusian.
