The Provincias Internas or Commandancy General of the Internal Provinces of the North (Comandancia y Capitanía General de las Provincias Internas) was a colonial, administrative district of the Spanish Empire, created in 1776 to provide more autonomy for the frontier provinces in the Viceroyalty of New Spain, present day northern Mexico and southwestern United States. The goal of its creation was to establish a unified government in political, military and fiscal affairs. Nevertheless, the Commandancy General experienced significant changes in its administration due to both experimentation to find the best government for the frontier region and bureaucratic in-fighting. Its creation was part of the Bourbon Reforms and was part of an effort to invigorate economic and population growth in the region to stave off encroachment on the region by foreign powers. During its existence, the Commandancy General encompassed the Provinces of Sonora y Sinaloa, Nueva Vizcaya, Las Californias, Nuevo México, and Coahuila y Tejas (formerly Nueva Extremadura).
