The Spaniards ruled the region 1521–1810, defining the Big Thicket's boundaries with the north as El Camino Real de los Tejas (Old San Antonio Road), a trail from central Texas to Nacogdoches; in the south as the Atascosito Road running from southwest Louisiana to Southeast Texas; to the west by the Brazos River; and to the east by the Sabine River. The Spanish established a settlement called Atascosito on the Atascosito Road at the Trinity River in 1756, renamed Villa de la Santissima Trinidad de la Libertad (Village of the Most Holy Trinity of Liberty) in 1831, later shortened to Liberty. However, this was little more than an outpost on the road and a stop on the river and interior areas were not developed in colonial times. Likewise, Beaumont (Tevis Bluff) was established in 1826 and Fort Teran, a long abandoned site in Tyler County on the Neches River were both primarily stops for river traffic.
