Florida is a state in the southeastern region of the United States, bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, and to the south by the Straits of Florida. Florida is the 22nd most extensive, the 3rd most populous, and the 8th most densely populated of the 50 United States. The state capital is Tallahassee, the largest city is Jacksonville, and the largest metropolitan area is the Miami metropolitan area. Much of Florida is a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. Its geography is notable for a coastline, omnipresent water and the threat of hurricanes. Florida has the longest coastline in the contiguous United States, encompassing approximately , and is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Much of the state is at or near sea level and is characterized by sedimentary soil. The climate varies from subtropical in the north to tropical in the south. Some of its most iconic animals, such as the American alligator, crocodile, Florida panther and the manatee, can be found in the Everglades National Park. Since the first European contact was made in 1513 by Spanish explorer Juan Ponce de León – who named it La Florida ( "The Flowery") upon landing there during the Easter season, Pascua Florida – Florida was a challenge for the European colonial powers before it gained statehood in the United States in 1845. It was a principal location of the Seminole Wars against the Indians, and racial segregation after the American Civil War. Today, Florida is distinguished by its large Hispanic community and high population growth, as well as its increasing environmental concerns. Its economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also known for its amusement parks, the production of oranges and the Kennedy Space Center. Florida culture is a reflection of influences and multiple inheritance; Native American, European American, Hispanic and African American heritages can be found in the architecture and cuisine. Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, and continues to attract celebrities and athletes. It is internationally known for golf, tennis, auto racing and water sports.
