Central and western Europe

The 18th century marked the establishment of most of the great Arabian studs of Europe, dedicated to preserving "pure" Arabian bloodstock. The Prussians set up a royal stud in 1732, originally intended to provide horses for the royal stables, and other studs were established to breed animals for other uses, including mounts for the Prussian army. The foundation of these breeding programs was the crossing of Arabians on native horses; by 1873 some English observers felt that the Prussian cavalry mounts were superior in endurance to those of the British, and credited Arabian bloodlines for this superiority.

Other state studs included the Babolna Stud of Hungary, set up in 1789, and the Weil stud in Germany (now Weil-Marbach or the Marbach stud), founded in 1817 by King William I of Württemberg. King James I of England imported the first Arabian stallion, the Markham Arabian, to England in 1616. Arabians were also introduced into European race horse breeding, especially in England via the Darley Arabian, Byerly Turk, and Godolphin Arabian, the three foundation stallions of the modern Thoroughbred breed, who were each brought to England during the 18th century. Other monarchs obtained Arabian horses, often as personal mounts. One of the most famous Arabian stallions in Europe was Marengo, the war horse ridden by Napoleon Bonaparte.

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.

This period also marked a phase of considerable travel to the Middle East by European civilians and minor nobility, and in the process, some travelers noticed that the Arabian horse as a pure breed of horse was under threat due to modern forms of warfare, inbreeding and other problems that were reducing the horse population of the Bedouin tribes at a rapid rate. By the late 19th century, the most farsighted began in earnest to collect the finest Arabian horses they could find in order to preserve the blood of the pure desert horse for future generations. The most famous example was Lady Anne Blunt, the daughter of Ada Lovelace and granddaughter of Lord Byron.
