In the early 20th century, with the 1910 revolution that ended the monarchy, the Alter Real strain faced extinction, as records were burned, stallions were gelded and the stud discontinued. Ruy d'Andrade, a specialist in Iberian horse breeds, saved two stallions and several mares, and was able to re-establish the strain, turning his herd over to the Portuguese Ministry of Agriculture in 1942, when the stud was reopened. The Portuguese state has maintained ownership of the stud, and continues to produce horses for use in high school dressage.
