The two tribes developed a strong friendship as they roamed and hunted their new land together. In the early 19th century, the Texas Congress granted each tribe two strips of land along the Trinity River. Their land was soon taken over by European-American settlers, leaving them homeless. Sam Houston, the governor of Texas, recommended that the state purchase for the Alabamas; although money was appropriated to buy for the Coushattas, the land was never bought. Either through marriage or special permission, many Coushatta went to live on the land given to the Alabama. Other Coushatta had stayed in an area in southern Louisiana near the Red River. Many of their descendants are enrolled members of the federally recognized Coushatta Tribe of Louisiana. By 1820, there were three main Alabama towns and three large Coushatta towns in east Texas, in the region known as the Big Thicket. In 1854, the Alabama were given 1,280 acres (5 km2) in Polk County. The following year, 640 acres (2.6 km2), also in Polk County, were given to the Coushattas. The Coushatta claim was disputed by white settlers in 1859. When the Coushatta lost the land claim, the Alabama invited them to live on their land claim. The federal government approved a large grant in 1928 to purchase additional land near the reservation; it was granted to the "Alabama and Coushatta tribes." Since that time, the reservation has officially been known as "Alabama-Coushatta". Origin myths focus on the interconnectedness of the tribes. One myth states that the two tribes sprouted from either side of a cypress tree. Another legend was recorded in 1857 from "Se-ko-pe-chi", one of the oldest Creeks in Indian Territory. He said that the tribes "sprang out of the ground between the Cohawba and Alabama Rivers." The symbol of the Alabama-Coushatta tribe comes from pre-contact Mississippian culture: two intertwined woodpeckers, now symbolic of the connection between the two tribes. The "obtusifolium" subspecies of the plant Pseudognaphalium obtusifolium is used in a compound decoction for nervousness and sleepiness, and in a decoction as a face wash for nerves and insomnia.
