The state of Arkansas was a part of the Confederate States of America during the American Civil War, and provided a source of troops, supplies, and military and political leaders for the fledgling country.
Arkansas had become the 25th state of the United States, on June 15, 1836, entering as a slave state. Antebellum Arkansas was still a wilderness in most areas, rural and sparsely populated. As a result, it did not have early military significance when states began seceding from the Union.
Arkansas refused to join the Confederate States of America until after Abraham Lincoln called for troops to respond to the provoked attack of Fort Sumter by Confederate forces in South Carolina. It finally seceded from the Union on May 6, 1861. Despite its relative lack of strategic importance, the state was the scene of numerous small-scale battles during the Civil War.
Several global companies are headquartered in the northwest corner of Arkansas, including Wal-Mart (the world's largest public corporation by revenue in 2007), J.B. Hunt and Tyson Foods. This area of the state has experienced an economic boom since the 1970s as a result.
In recent years, automobile parts manufacturers have opened factories in eastern Arkansas to support auto plants in other states. Additionally, the city of Conway is the site of a school bus factory.
Tourism is also very important to the Arkansas economy; the official state nickname "The Natural State" was originally created (as "Arkansas Is A Natural") for state tourism advertising in the 1970s, and is still regularly used to this day.
