Prince Aly Khan, The Aga Khan III’s son, took over the program upon his father’s death in 1957, and he saw success two years later with the champion filly Petite Etoile. The Aga Khan IV then took control of the Thoroughbred operation in 1960 following the death of his father. He earned France’s leading owner title in his first year at the helm, and success followed in the years to come with names like Blushing Groom, Shergar, and Darshaan. Following the turn of the century, his runners of note have included Sinndar, Dalakhani, Zarkava, and Siyouni.
