Nochistlán (Spanish ) is a town in the Mexican state of Zacatecas. Nuño Beltrán de Guzmán, on December 3, 1531, hired Cristóbal de Oñate to establish a village in Nochistlán; the village would be named Guadalajara to honor Guzmán for having been born in Guadalajara. Guadalajara was founded in Nochistlán on January 5, having as officials Cristóbal de Oñate, Sancho Ortíz de Zuñiga and Miguel Ibarra. They worked at this project for only 16 months and created the first layout of Guadalajara.
The first news that we have regarding the natives of these lands points to the Tecuexe. These people established settlements around 1000. Later in the 12th century a new group of people moved in, these people were called Caxcan and they were from the valley in Tuitlán, which is now found in the municipality of Villa Nueva, Zacatecas. The Caxcan established Nochistlán by driving out the Tecuexe by force.
