Near Route of Alonso de Leon Expeditions
Los Indios, TX
When French explorer René La Salle landed on the Texas coast in 1684, Spain feared its rival was seizing the region, and the Mexican viceroy dispatched Alonso de León to answer the threat. Across five expeditions from 1686 to 1690, de León crossed the Rio Grande, hunted for French intruders, and finally located and destroyed the ruins of La Salle's Fort St. Louis near Matagorda Bay. His 1690 march into East Texas planted the first Spanish mission, San Francisco de los Tejas, launching Spain's colonization of Texas.
