(which make up what the Census Bureau Division calls West South Central States) are almost always considered the "core" of the region. As part of the East South Central States sub-group of the Census Bureau classification, Alabama, Mississippi, Tennessee and Kentucky are also frequently listed under the heading.

History

The history of the South Central states is dominated by the conflict and interaction between three cultural-linguistic groups: the Anglosphere (first Great Britain and then the United States), the Hispanidad (first Spain then Mexico), and the Francophonie (always France). In the 17th and 18th centuries, Spain and France maneuvered for control of Texas; with the Spanish based in Mexico, and the French in Louisiana. During the War of the Quadruple Alliance hostilities spread to the New World and the French troops from Natchitoches, Louisiana, Natchitoches briefly captured the capital of Spanish Texas, Los Adaes, in what is now western Louisiana. The French were not able to wrest control of Texas from Spain, and by the early 19th century sold their North American holdings to the United States in the Louisiana Purchase, which comprised slightly less than half of what is today the South Central United States. During the Texas Revolution (1835–1836), a rebellion of United States immigrants and Tejanos (Texas Mexicans), put up an armed resistance against the Centralist Republic of Mexico. The Battle of the Alamo was a major turning point during the Texas Revolution. This battle would lead to many Texians deciding to join the Texian Army. Texians would defeat the Mexican Army at the Battle of San Jacinto later on, leading to Texas declaring themselves an independent country in 1836, however Mexico viewed them as a rebellious province. Texas would eventually be admitted as a U.S. state in 1845. The official West and East South Central states of Texas, Arkansas, Louisiana, Mississippi, Alabama and Tennessee would secede from the Union and join the Confederate States of America, Confederacy during the Civil War. Kentucky was a Border states (American Civil War), border state that remained with the Union (American Civil War), Union. Oklahoma, although Indian Territory at the time, was home to five major Native-American tribes, of which the majority allied themselves with the Confederacy. Oklahoma territory and Indian Territory would merge into the State of Oklahoma, when it became the 46th U.S. state in 1907. All of these states are usually considered to make up a larger part of the American South, both historically and culturally, as well as classified by the United States Census Bureau, U.S. Census Bureau.

Geography

The climate varies from the semi-tropical in the Mississippi Delta, South Louisiana, and Southeast Texas, to the dry Chihuahuan desert in West Texas. The southeastern portions include the Appalachian mountains in Alabama and Tennessee and the Piney Woods of East Texas, Louisiana, and southern Arkansas and the Mississippi Delta. A large portion of the northeastern quarter of the region is mountainous, with the Ozark Mountains, Ozark and Ouachita Mountains of Arkansas and eastern Oklahoma. The northwest quarter of the region is dominated by the Great Plains which become progressively drier west of 100° W, forming the North American Llano Estacado. The southwestern portions border the Rio Grande, and are generally drier than other areas of the South Central United States. Texas is the largest South Central state by both area and population. Texas is still home to over half the region's population. The largest city in the region, Houston, is located in
