lifestyle. This occurred by the 1730s, when they had acquired enough horses to put all their people on horseback. The horse enabled the Plains Indians to gain their subsistence with relative ease from the seemingly limitless bison herds. Riders were able to travel faster and farther in search of bison herds and to transport more goods, thus making it possible to enjoy a richer material environment than their pedestrian ancestors. For the Plains peoples, the horse became an item of prestige as well as utility. They were extravagantly fond of their horses and the lifestyle they permitted. The first Spanish conqueror to bring horses to the new world was Hernán Cortés in 1519. However, Cortés only brought about sixteen horses with his expedition. Coronado brought 558 horses with him on his 1539–1542 expedition. At the time, the Indians of these regions had never seen a horse. Only two of Coronado's horses were mares, so he was highly unlikely to have been the source of the horses that Plains Indians later adopted as the cornerstone of their culture. In 1592, however, Juan de Oñate brought 7,000 head of livestock with him when he came north to establish a colony in New Mexico. His horse herd included mares as well as stallions. Pueblo Indians learned about horses by working for Spanish colonists. The Spanish attempted to keep knowledge of riding away from Native people, but nonetheless, they learned and some fled their servitude to their Spanish employers—and took horses with them. Some horses were obtained through trade in spite of prohibitions against it. Other horses escaped captivity for a feral existence and were captured by Native people. In all cases, the horse was adopted into their culture and herds multiplied. By 1659, the Navajo from northwestern New Mexico were raiding the Spanish colonies to steal horses. By 1664, the Apache were trading captives from other tribes to the Spanish for horses. The real beginning of the horse culture of the plains began with the Pueblo Revolt of 1680 in New Mexico and the capture of thousands of horses and other livestock. They traded many horses north to the Plains Indians. In 1683 a Spanish expedition into Texas found horses among Native people. In 1690, a few horses were found by the Spanish among the Indians living at the mouth of the Colorado River of Texas and the Caddo of eastern Texas had
