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.
History of Tampa, Florida
On January 10, 1861, the state of Florida seceded from the United States along with the rest of the American South to form the Confederate States of America, touching off the American Civil War.
Two Tampa locals attended the Secession Convention; judge and "Florida Peninsular" newspaper editor Simon Turman and lawyer James Gettis. The "Peninsular" was one of Tampa's oldest media publications. Both Turman and Gettis signed the Ordinance of Secession. Gettis's law partner was Henry L. Mitchell.
