One of George Washington's primary mounts during the American Revolutionary War was a gray half-Arabian horse named Blueskin, sired by the stallion "Ranger", also known as "Lindsay's Arabian", said to have been obtained from the Sultan of Morocco. Other Presidents are linked to ownership of Arabian horses; in 1840, President Martin Van Buren received two Arabians from the Sultan of Oman, and in 1877, President Ulysses S. Grant obtained an Arabian stallion, Leopard, and a Barb, Linden Tree, as gifts from Abdul Hamid II, the "Sultan of Turkey".
