and Indian and Spanish captives taken by the Comanche. The Utes traded their goods for cloth, blankets, guns, horses, maize, flour, and ornaments. A number of Ute learned Spanish through trading. The Spanish "seriously guarded" trade with the Utes, limiting it to annual caravans, but by 1750 they were reliant on the trade with the Utes, their deerskin being a highly sought commodity. The Utes also traded in slaves, women and children captives from Apache, Comanche, Paiute and Navajo tribes. In 1637, the Spanish fought with the Utes, 80 of whom were captured and enslaved. Three people escaped with horses. Their lifestyle changed with the acquisition of horses by 1680. They became more mobile, more able to trade, and better able to hunt large game. Ute culture changed dramatically in ways that paralleled the Plains Indian cultures of the Great Plains. They also became involved in the horse and slave trades and respected warriors. Horse ownership and warrior skills developed while riding became the primary status symbol within the tribe and horse racing became common. With greater mobility, there was increased need for political leadership. During this time, few people entered Ute territory. Exceptions to this include the Dominguez–Escalante expedition of 1776 and French trappers passing through the area or establishing trading posts beginning in the 1810s. The French expedition recorded meeting members of the Moanunts and Pahvant bands. Warrior culture After the Utes acquired horses, they started to raid other Native American tribes. While their close relatives, the Comanches, moved out from the mountains and became Plains Indians as did others including the Cheyenne, Arapaho, Kiowa, and Plains Apache, the Utes remained close to their ancestral homeland. The south and eastern Utes also raided Native Americans in New Mexico, Southern Paiutes and Western Shoshones, capturing women and children and selling them as slaves in exchange for Spanish goods. They fought with Plains Indians, including the Comanche, who had previously been allies. The name "Comanche" is from the Ute word for them, kɨmantsi, meaning enemy. The Pawnee, Osage and Navajo also became enemies of the Plains Indians by about 1840. Some Ute bands fought against the Spanish and Pueblos with the Jicarilla Apache and the Comanche. The Ute were sometimes friendly but sometimes hostile to the Navajo. The Utes were skilled warriors who specialized in horse mounted combat. War with neighboring tribes was mostly fought for gaining prestige, stealing horses,
