 The Chichimeca Jonaz arrived in the 14th century and mainly settled in Tembladera, El Portugués and the areas around the Extoraz River and the Cerro de Media Luna, in the east where the land is less arid.The first Spanish in the region were led by Nicolás de San Luis Montañez in the mid 16th century.Because of their battles with the Chichimecas, San Luis Montañez was named “Capitan of the Chichimecas.” The Pames did not offer much resistance to Spanish incursion but the Chichimeca Jonaz did.
