During the mid-19th century, the need for Arabian blood to improve the breeding stock for light cavalry horses in Europe resulted in more excursions to the Middle East. Queen Isabel II of Spain sent representatives to the desert to purchase Arabian horses and by 1847 had established a stud book; her successor, King Alfonso XII imported additional bloodstock from other European nations. By 1893, the state military stud farm, Yeguada Militar was established in Córdoba, Spain for breeding both Arabian and Iberian horses. The military remained heavily involved in the importation and breeding of Arabians in Spain well into the early 20th century, and the Yeguada Militar is still in existence today.
