News about the insurgent movement started by Miguel Hidalgo on September 16, 1810, was virtually nonexistent to the inhabitants of the New Kingdom of León, until a letter sent by Felix María Calleja to then New Leon governor Manuel de Santa María on September, 29. The distance and poor condition of access routes were a factor for the delayed post service, from the capital of New Spain to the relatively remote northern provinces. The impulse toward insurgency against Spain was rapidly suffocated in the region. The New Kingdom of León, along with Provincias Internas de Oriente, was in its first years one of the regions with relatively less support for the insurgent cause. As for the New Kingdom of León, among several explanations for this fact was that it was one of the last territories colonized by the Spanish Empire in New Spain. Also, it was the province which reported the highest proportion of people of Spanish and Criollo ancestry, as reported in the "revillagigedo" 1790 census, followed by Texas and Coahuila.
