At the end of the 19th century, the Spanish Army was entrusted with promoting horse breeding. In order to provide horses of the Arabian breed, in the first third of the 20th century, several commissions to the East were made to import desert horses. Between the end of 1926 and the beginning of 1927, this commission was carried out by Mayor Francisco Javier Nanetti and Captain José Sevillano Cousillas. Twenty-five typescript pages of the latter are the description of this journey that culminated in the successful importation of fourteen mares and six stallions. All of them arrived healthy in Jerez de la Frontera and some of them left their genetic imprint in modern Spanish Arabian. Includes thirty-four unpublished photos
