 The Provincias Internas were the brainchild of José de Gálvez.He hit upon the idea during his time as royal "Visitador General" (Inspector General) to New Spain from 1761 to 1772.His initial idea was to create a full-fledged viceroyalty or captaincy general out of the northern provinces, but the low population of the area and large military expenses of the area in comparison to its revenues, prevented this.
