Sultan's Great Day
Sultan's Great Day (March 22, 1981 – March 22, 2004) was a black American Saddlebred stallion sired by Supreme Sultan, out of the mare Supremes Cassandra.  Great Day, as he was commonly called, was a twice World's Champion Fine Harness Stallion.  In his debut performance, he earned the title 1983 2-year-old World's Champion fine harness stallion.  Other prestigious wins followed during his 2 and 3 year old years.  He was retired to stud at the age of 4, but was shown a few more times in later years.  Great Day was referred to as "one of the most prolific sires of world's champions throughout the 1990s". He sired 387 registered offspring of which 106 were ribbon winners, 63 were futurity ribbon winners, and 24 went on to become champions in their respective disciplines.

Sultan was purchased by William Shatner after he won his second World's Championship Horse Show. He then started living at Belle Reve Farm.

Shatner commented on Sultan's Great Day, “Great Day is to me what a Rodin statue is to an art collector, except that this work of art is alive.” Shatner said "the magnificent part of owning horses is breeding horses." Sultan's Great Day was bred to champion Saddlebred mares, and produced champions.
