At the earliest period of which we have any authentic information, this territory of Spain was divided into the kingdoms of Mexico, New Galicia, and New Leon; the colony of New Santander; and the provinces of Coahuila, Texas, New Biscay, Sonora, New Mexico and the two Californias. This arrangement was extremely indefinite; but, in 1776, the country was divided into twelve intendancies: Merida, Oajaca, Vera Cruz, Puebla, Mexico, Valladolid, Guanajuato, Guadalajara, Zacatecas, San Luis Potosi, New Biscay, and Sonora; and the three provinces of New Mexico, and Alta and Nueva California. The intendancy of San Luis Potosi, included New Leon, New Santander, Coahuila and Texas, and San Luis Potosi, proper;--the intendancy of New Biscay embraced the provinces of Durango and Chihuahua; and the intendancy of Sonora took in the provinces of Sinaloa, Ostimuri, and Sonora. Each intendancy was subdivided into _subdelegaciones_. Another division cut off New Spain, proper, from the _Provincias Internas_. These last named provinces included all the territory lying north and northwesterly of the intendancies of Zacatecas and Guadalajara, or the kingdom of Nueva Gallicia. The "_Provincias Internas del Vireynato_," must be distinguished from the "_Provincias Internas de la Commandancia de Chihuahua_," which, in 1779, were comprised in a General-Captaincy. The two intendancies New Biscay and Sonora, then part of San Luis Potosi, belonged to the provinces of Coahuila and Texas. The interior provinces of the viceroyalty were the intendancy of San Luis Potosi, including the provinces of New Leon and New Santander. The _actual_ kingdom of New Spain was composed of the intendancies of Mexico, Puebla, Vera Cruz, Guadalajara, Valladolid, Zacatecas, Guanajuato, Oajaca, Merida, and San Luis, proper, and the two Californias. In the year 1807, the "_Provincias Internas_" were divided into _western_ and _eastern_, and two general commandancies created. 1st. The _Provincias Internas Occidentales_, or _Western_, were the intendancies of Sonora, Durango, with Chihuahua (new Biscay); the province of New Mexico, and the two Californias. 2d. The _Provincias Internas Orientales_, or _Eastern_, were, Coahuila, Texas, New Santander and New Leon. * * * * *
