when did the navajo arrive in the southwest
Navajo Archaeological and historical evidence suggests the Athabaskan ancestors of the Navajos and Apaches entered the Southwest around 1400 CE.[7][8] The Navajo oral tradition is said to retain references of this migration.[citation needed]
Indian Trade Trade with the Spanish Trading between Spanish settlers and Native Americans was rare and occurred in parts of New Mexico and California. The Spanish mainly intended to spread the Christian faith to Indians and to use them as slaves for work. The most significant effect of trading with the Spanish was the introduction of the horse to the Ute in New Mexico. Gradually, horses bred and their use was adopted across the Great Plains, dramatically altering the lifestyles and customs of many Native American tribes. Many Indians switched from a hunter- gatherer economy to a nomadic lifestyle after they began using horses for transportation. They had a greater range for hunting bison and trading with other tribes.[11]
