The National Colonization Law of August 18, 1824, which superseded the Imperial Colonization Law, determined how Texas would be peopled. It stipulated that those wishing colonization contracts should make arrangements with the legislatures of individual states and not the federal government. In the case of Texas, an empresario would have to negotiate with Saltillo, the capital of Coahuila since Texas was merged with that state. Government officials in Coahuila would thus define the course of immigration by determining whether those receiving contracts would be Anglos, Europeans, or Mexicans.
