and revenge. Men would organize themselves into war parties made up of warriors, medicine men, and a war chief who led the party. To prepare themselves for battle Ute warriors would often fast, participate in sweat lodge ceremonies, and paint their faces and horses for special symbolic meanings. The Utes were master horsemen and could execute daring maneuvers on horseback while in battle. Most plains Indians had warrior societies, but the Ute generally did not - the Southern Utes developed such societies late, and soon lost them in reservation life. Warriors were exclusively men but women often followed behind war parties to help gather loot and sing songs. Women also performed the Lame Dance to symbolize having to pull or carry heavy loads of loot after a raid. The Utes used a variety of weapons including bows, spears and buffalo-skin shields, as well as rifles, shotguns and pistols which were obtained through raiding or trading. Contact with other European settlers The Ute people traded with Europeans by the early 19th century including at encampments in the San Luis Valley, Wet Mountains, and the Upper Arkansas Valley and at the annual Rocky Mountain Rendezvous. Native Americans also traded at annual trade fairs in New Mexico, which were also ceremonial and social events lasting up to ten days or more. They involved the trading of skins, furs, foods, pottery, horses, clothing, and blankets. In Utah, Utes began to be impacted by European-American contact with the 1847 arrival of Mormon settlers. After initial settlement by the Mormons, as they moved south to the Wasatch Front, Utes were pushed off their land. Wars with settlers began about the 1850s when Ute children were captured in New Mexico and Utah by Anglo-American traders and sold in New Mexico and California. The rush of Euro-American settlers and prospectors into Ute country began with an 1858 gold strike. The Ute allied with the United States and Mexico in its war with the Navajo during the same period. There was continued pressure by the Mormons to push the Utah Utes off their land. This resulted in the Walker War (1853–54). By the mid-1870s, the Utes had been moved onto a reservation, less than 9% of its former land. The Utes found it to be very inhospitable and they tried to continue hunting and gathering off the reservation. In the meantime, the Black Hawk War (1865–72) occurred in Utah.
