The valley was used for more than 9,000 years as a major route for travel and trade according to archaeological evidence.[5] Pit houses and room blocks provided the first permanent housing for inhabitants beginning about 900 A.D.[5] Ancestral Puebloans are believed to have moved into the area of the Taos Valley and tributaries of the Rio Grande at that time.[6]
It was the home of the puebloan people of Taos Pueblo beginning about 1100[7] or 1200 A.D.[5] At that time, construction began on multiple dwellings.[7] It was first visited by people of European descent in the 1500s, when Capitan Hernando Alvarado arrived on August 29, 1540. He was part of Francisco Vázquez de Coronado's expedition. Alvarado met the Tiwa people of Taos Pueblo.[8] Fray Francisco de Zamora spread the Catholic religion throughout the Taos Valley, will based at the Taos Pueblo from 1610 to 1617.[7] The Spanish were driven out of the area by the Puebloans in 1680.[7] Sixteen years later, Diego de Vargas resettled the area around Ranchos de Taos, the Taos Pueblo, and Taos Plaza. Taos Valley had a population of 306 people of Spanish descent in 67 families in 1776. The most populated area in the valley at that time was Ranchos de Taos.[7] The Spanish brought modern methods for irrigation called acequias and introduced fruit and vegetables to the region. They also introduced livestock.[5] The Puebloans taught the Spanish how to build adobe structures.[5]
