The PRE horse dates back into the 16th Century, during the times of great change in what was going to be modern europe and during the time where the Spanish empire was the greatest in Europe. The spanish horse became popular during this time and influenced the founding of many breeds across Europe. They reflect both the past and the present, and allow the sense of future possilbilities. By 1912, Spanish Ministry of Defense Breeding Service (known as the Crua Caballar) initiated the PRE Studbook. Following a series of zootechnical rules and regulations implemented by the EU and the Ministry of Agriculture, Fisheries and Food, the PRE studbook was turned over the ANCCE, thus guarantee the purity of this century-old breed. ANCCE is the only PRE studbook for PRE horses worldwide. ANCCE establishes the agreements and the procedures with breeders and governing bodies in various countries to manage the breed in those locations, Australia having AUSPRE. The breeding program was launched in 2003, since then methodologies have been establish to fine tune the complete and objective control of conformation and functional performances. This provides breeders the tools to asess their stocks and plan their breeding to better assist them in breeding the best stock they can.
