Alabama () is a state in the Southeastern region of the United States, bordered by Tennessee to the north; Georgia to the east; Florida and the Gulf of Mexico to the south; and Mississippi to the west. Alabama is the 30th largest by area and the 24th-most populous of the U.S. states. With a total of 1,500 miles (2,400 km) of inland waterways, Alabama has among the most of any state.Alabama is nicknamed the Yellowhammer State, after the state bird. Alabama is also known as the "Heart of Dixie" and the "Cotton State". The state tree is the longleaf pine, and the state flower is the camellia. Alabama's capital is Montgomery. The largest city by population is Birmingham, which has long been the most industrialized city; the largest city is Huntsville. The oldest city is Mobile, founded by French colonists in 1702 as the capital of French Louisiana. Greater Birmingham is Alabama's largest urban economy, its most populous urban area, and its economic center.The state's geography is diverse, with the north dominated by the mountainous Tennessee Valley and the south by Mobile Bay, a historically significant port. Politically, as part of the Deep South, Alabama is now a predominantly conservative state, and it is known for its Southern culture. Today, American football, particularly at the college level at schools like the University of Alabama, Auburn University, Alabama A&M University, Alabama State University and Jacksonville State University is a major part of the state's culture.
Originally home to many native tribes, present-day Alabama was a Spanish territory beginning in the sixteenth century until the French acquired it in the early eighteenth century, founding Mobile in 1702. The British won the territory in 1763 until losing it in the American Revolutionary War. Spain held Mobile as part of Spanish West Florida until 1813; Spain ceded West Florida to the US in 1819. In December 1819, Alabama was recognized as a state. During the antebellum period, Alabama was a major cotton producer and widely used African-American slaves on its plantations. In 1861, the state seceded from the United States to become part of the Confederate States of America, with Montgomery acting as its first capital, and rejoined the Union in 1868.
From the American Civil War until World War II, Alabama, like many states in the southern U.S., suffered economic hardship, in part because of its continued dependence on agriculture. Similar to other former slave states, Alabamian legislators employed Jim Crow laws to disenfranchise and otherwise discriminate against African Americans from the end of the Reconstruction Era up until at least the 1970s. Despite the growth of major industries and urban centers, white rural interests dominated the state legislature from 1901 to the 1960s. During this time, urban interests and African Americans were markedly under-represented. High-profile events such as the Selma to Montgomery march made the state a major focal point of the civil rights movement in the 1950s and 1960s. Following World War II, Alabama grew as the state's economy changed from one primarily based on agriculture to one with diversified interests. The state's economy in the 21st century is based on management, automotive, finance, manufacturing, aerospace, mineral extraction, healthcare, education, retail, and technology.
