Late in the spring of 1783, a Franciscan friar, Antonio de los Reyes, arrived in the Province of Sonora and Sinaloa, the first prelate for the newly created bishopric of Northwest New Spain. The bishop was accompanied by his young nephews, Padre José Almada y Reyes and his brother Antonio. A third brother had decided to remain behind in Spain with his parents. The brothers were hidalgos, from the town of Aspe in the province of León.
New Spain was expanding northwestward and the Almada brothers were part of the large influx of peninsulares immigrating from the mother country in the latter third of the 18th century. Their uncle, the bishop, represented royal recognition and promotion of that movement. Like the Almadas, most of the immigrants coming to the Northwest were from the small towns and cities of northern Spain. They brought with them a tradition of urban life in the peninsula dating back into at least the eleventh century. For them, the town was the focal point of civilized society — the center of learning, of business, and of whatever level of culture society had achieved. Not surprisingly, they settled in the embryonic urban centers then emerging in the Province of Sonora and Sinaloa. Urban life was what they knew and what they wanted. They aimed to re-create in the Northwest what they had grown up in back home.
