The Andalu­sian, also known as the Pure Span­ish Horse or PRE (Pura Raza Españo­la), is a horse breed from the Iber­ian Penin­su­la, where its ances­tors have lived for thou­sands of years. The Andalu­sian has been rec­og­nized as an indi­vid­ual breed since the 15th cen­tu­ry, and its con­for­ma­tion has changed very lit­tle over the cen­turies. Through­out its his­to­ry, it has been known for its prowess as a war horse, and was prized by the nobil­i­ty. The breed was used as a tool of diplo­ma­cy by the Span­ish gov­ern­ment, and kings across Europe rode and owned Span­ish hors­es. Dur­ing the 19th cen­tu­ry, war­fare, dis­ease and cross­breed­ing reduced herd num­bers dra­mat­i­cal­ly, and despite some recov­ery in the late 19th cen­tu­ry, the trend con­tin­ued into the ear­ly 20th cen­tu­ry. Exports of Andalu­sians from Spain were restrict­ed until the 1960s, but the breed has since spread through­out the world, despite their low pop­u­la­tion. In 2010, there were more than 185,000 reg­is­tered Andalu­sians world­wide. Strong­ly built, and com­pact yet ele­gant, Andalu­sians have long, thick manes and tails. Their most com­mon coat col­or is gray, although they can be found in many oth­er col­ors. They are known for their intel­li­gence, sen­si­tiv­i­ty and docil­i­ty. A sub-strain with­in the breed known as the Carthu­sian, is con­sid­ered by breed­ers to be the purest strain of Andalu­sian, though there is no genet­ic evi­dence for this claim. The strain is still con­sid­ered sep­a­rate from the main breed how­ev­er, and is pre­ferred by breed­ers because buy­ers pay more for hors­es of Carthu­sian blood­lines. There are sev­er­al com­pet­ing reg­istries keep­ing records of hors­es des­ig­nat­ed as Andalu­sian or PRE, but they dif­fer on their def­i­n­i­tion of the Andalu­sian and PRE, the puri­ty of var­i­ous strains of the breed, and the legal­i­ties of stud book own­er­ship. At least one law­suit is in progress , to deter­mine the own­er­ship of the Span­ish PRE stud book. The Andalu­sian is close­ly relat­ed to the Lusi­tano of Por­tu­gal, and has been used to devel­op many oth­er breeds, espe­cial­ly in Europe and the Amer­i­c­as. Breeds with Andalu­sian ances­try include many of the warm­bloods in Europe as well as west­ern hemi­sphere breeds such as the Azteca. Over its cen­turies of devel­op­ment, the Andalu­sian breed has been select­ed for ath­leti­cism and sta­mi­na. The hors­es were orig­i­nal­ly used for clas­si­cal dres­sage, dri­ving, bull­fight­ing, and as stock hors­es. Mod­ern Andalu­sians are used for many eques­tri­an activ­i­ties, includ­ing dres­sage, show jump­ing and dri­ving. The breed is also used exten­sive­ly in movies, espe­cial­ly his­tor­i­cal pic­tures and fan­ta­sy epics.
