The inhabitants of New Mexico had from the epoch of Onate the desire to have an bishopric, that increased in the measure that autonomists were increasing the desires. The motives were varied. The Franciscans to avoid the control of the bishop of Durango; the inhabitants because they saw in it a form of spiritual and material promotion, as well as the development of centers of formation. The project almost was realized in the Cortes de Cadiz after the intervention of the deputy for New Mexico, Pedro Baptista Pino, in collaboration with the journalist Juan Lopez Cancelada. The return of Fernando VII would finish with the project. It would be necessary to wait to the annexation to the United States in order that the new diocese was created.
