The first European contact was made in 1513 by Spanish explorer Juan Ponce de León, who called it la Florida ([la flo'?iða] "the land of flowers") upon landing there in the Easter season, known in Spanish as 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 Native Americans, and racial segregation after the American Civil War.
Today, Florida is distinctive for its large Cuban expatriate community and high population growth, as well as for its increasing environmental issues.

Florida is also renowned for amusement parks, orange crops, winter vegetables, the Kennedy Space Center, and as a popular destination for retirees. Florida is the flattest state in the United States.
