Maritime history of Florida
Spain ceded Florida to the United States as part of the Adams–Onís Treaty of 1819, and Florida became a U.S. territory in 1821. Coastal trade with other markets continued to expand and towns like Jacksonville, Pensacola and Tampa became important ports. After becoming a U.S. territory, the federal government began building a series of lighthouses as aids to navigation along the coasts of Florida to mark dangerous headlands, shoals, bars and reefs.
Florida
The first European contact was made in 1513 by Spanish explorer Juan Ponce de León, who called it "la Florida" ( "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.
