The Bedouin way of life depended on camels and horses: Arabians were bred to be war horses with speed, endurance, soundness, and intelligence. Because many raids required stealth, mares were preferred over stallions as they were quieter, and therefore would not give away the position of the fighters. A good disposition was also critical; prized war mares were often brought inside family tents to prevent theft and for protection from weather and predators. Though appearance was not necessarily a survival factor, the Bedouin bred for refinement and beauty in their horses as well as for more practical features.
