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 cracker
Florida crackers were colonial-era English and American pioneer settlers and their descendants in what is now the U.S. state of Florida. The first of these arrived in 1763 after Spain traded Florida to Great Britain following the latter's victory over France in the Seven Years' War.
