These homes were known as hogans, and their doors faced the east to be sure the sun would shine in. When the Spanish came into their territory in the 1600's, the Navajo who use their sheep for things like clothing and food. They would set up trading posts within the Spanish towns with their handmade items in order to barter for things that they needed.
