why did the spanish look for la salles colony
French colonization of Texas Spain learned of La Salle's mission in 1686. Concerned that the French colony could threaten Spain's control over the Viceroyalty of New Spain and the unsettled southeastern region of North America, the Crown funded multiple expeditions to locate and eliminate the settlement. The unsuccessful expeditions helped Spain to better understand the geography of the Gulf Coast region. When the Spanish finally discovered the remains of the French colony at the fort in 1689, they buried the cannons and burned the buildings. Years later, Spanish authorities built a presidio at the same location. When the presidio was abandoned, the site of the French settlement was lost to history.
