Florida ( FLORR-ih-də; Spanish: [floˈɾiða] ) is a state in the Southeastern and South Atlanticregions of the United States. It borders the Gulf of Mexico to the west, Alabama to the northwest, Georgia to the north, the Atlantic Ocean to the east, the Straits of Florida to the south, and The Bahamas to the southeast. About two-thirds of Florida occupies a peninsula between the Gulf of Mexico and the Atlantic Ocean. It has the longest coastline in the contiguous United States, spanning approximately 1,350 miles (2,170 km), not including its many barrier islands. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. With a population of over 23 million, it is the third-most populous state in the United States and ranks seventh in population density as of 2020. Florida spans 65,758 square miles (170,310 km), ranking 22nd in area among the states. The Miami metropolitan area, anchored by the cities of Miami, Fort Lauderdale, and West Palm Beach, is the state's largest metropolitan area, with a population of 6.138 million; the most populous city is Jacksonville. Florida's other major population centers include Tampa Bay, Orlando, Cape Coral, and the state capital of Tallahassee.
Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first documented European to make landfall in the region and named it La Florida (Spanish for "land of flowers"; [la floˈɾiða]), giving the territory its present name. Spain subsequently incorporated Florida into the Spanish Empire in the early 16th century. In 1565, it founded St. Augustine, the oldest continuously inhabited European-established settlement in the continental United States. The region was frequently coveted and attacked by Great Britain throughout the 18th century. Britain briefly gained control of Florida in 1763, but Spain recovered it in 1783 following the British defeat in the American Revolutionary War. Florida remained under Spanish rule until it was ceded to the United States in 1821, in exchange for U.S. recognition of Spanish sovereignty in Texas and the resolution of the border dispute along the Sabine River. Florida was admitted as the 27th state on March 3, 1845, and was the principal location of the Seminole Wars (1816–1858), the longest and most extensive of the American Indian Wars. The state seceded from the Union on January 10, 1861, becoming one of the seven original Confederate States, and was readmitted to the Union after the Civil War on June 25, 1868.
