The Bedouin tribes of the desert, believing the horse to be a gift from God, told many romantic tales of the Arabian's beginnings.
One such legend claims God fashioned the desert south wind into a creature who "shall fly without wings".
No matter how the horse came to the desert, Bedouins took them as prized members of their households.
Individual horses were selected for the gentle, affectionate nature, the striking look and proud spirit the breed is known for today.
The Arabian was also bred to withstand long treks across the desert and the tribal wars which sometimes followed such trips.
The Bedouins developed horses with strength, courage and stamina required for survival, and for the speed and responsiveness needed to win the tribal skirmishes. 
All in all, the Arabian Horse developed a significant list of attributes!
Ancient Bedouin breeders were careful to record bloodlines and jealously guarded the purity of their Arabians.
As a result, even though centuries have passed, today's Arabian cannot be mistaken for any other breed.
Whether ridden English or Western, shown in Park classes or Halter, or even used for Trail riding, Arabians have the same basic distinctive appearance.
The Arabian's head has a characteristic dished profile with a prominent eye, large nostrils and small teacup muzzle.
His gracefully arched neck rises out of a long sloping shoulder and broad chest.
A short, strong back and high tail carriage complete the picture.
Arabians come in grey, chestnut, bay and an occasional solid black. Although some individuals will vary, most are between 14.2 and 15.2 hands in height.
