Texas Under France (1685-1690)
French flag.

In an attempt to expand west of Louisiana, France in 1685, laid claim to eastern Texas near the Gulf Coast. Though claimed by Spain, the nearest Spanish settlements were hundreds of miles away. French nobleman Rene Robert Cavelier, Sieur de la Salle, founded a colony called Fort St. Louis. But by 1690 shipwreck, disease, famine, hostile Indians, and internal strife ending in La Salle's murder by one of his own company doomed the colony and France's claim. The French flag – actually the royal ensign for ships and forts – featured Fleurs-de-lis on a white field.
