Spanish Texas, situated on the border of Spain’s vast North American empire, encompassed only a small portion of what is now the Lone Star State. The province lay above the Nueces River to the east of the Medina River headwaters and extended into Louisiana. Over time, Texas was a part of four provinces in the Viceroyalty of New Spain (Colonial Mexico). The El Paso area was under the jurisdiction of New Mexico, the missions founded near La Junta de los Ríos were under Nueva Vizcaya, the coastal region from the Nueces River to the Rio Grande and thence upstream to Laredo was under Nuevo Santander after 1749, and Texas was initially under joint jurisdiction with the province of Coahuila.
