The French colonization of Texas began with Fort Saint Louis in present-day southeastern Texas. It was established in 1685 near Arenosa Creek and Matagorda Bay by explorer Robert Cavelier de La Salle. He intended to found the colony at the mouth of the Mississippi River, but inaccurate maps and navigational errors caused his ships to anchor instead 400 miles (640 km) to the west, off the coast of Texas. The colony survived until 1688.
