The region was primarily controlled by the Spanish for the first couple centuries of contact, until the Texas Revolution. They were not particularly kind to their native populations—even less so with the Caddoans, who were not trusted as their culture was split between the Spanish and the French. When the Spanish briefly managed to conquer the Louisiana colony, they decided to switch tactics and attempt being exceedingly friendly to the Indians, which they continued even after the French took back the colony. After the 1803 Louisiana Purchase, the United States inherited this odd circumstance. The Caddoans preferred the company of Americans and almost the entire population of them migrated into the states of Louisiana and Arkansas. The Spanish felt jilted after having spent so much time and effort and began trying to lure the Caddo back, even promising them more land. Seemingly without actually knowing how they came by it, the United States (who had begun convincing tribes to self-segregate from whites by selling everything and moving west ever since they gained the Louisiana Purchase) faced an overflow of native peoples in Missouri and Arkansas and were able to negotiate with the Caddoans to allow several displaced peoples to settle on unused lands in eastern Texas. They included the Muscogee, Houma Choctaw, Lenape and Mingo Seneca, among others, who all came to view the Caddoans as saviors, making those peoples highly influential.
