What southern state was still frontier On the late 1800s?

In the late 1800s, Arkansas was considered a frontier state in the South. Although it was admitted to the Union in 1836, much of its land remained undeveloped and sparsely populated during this period. The state was characterized by its rugged terrain, dense forests, and a growing demand for agricultural expansion, particularly in cotton farming. The frontier status contributed to a unique blend of cultures and a slower pace of development compared to more urbanized areas.
