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.
Sanford, Florida
The Mayaca or Jororo Indians inhabited the shores of Lake Monroe at the time of European contact. By 1760, however, war and disease had decimated the tribe, which would be replaced by the Seminole Indians. Florida was acquired by the United States from Spain in 1821, but the Seminole Wars would delay settlement. In 1835, the Seminoles burned the port of Palatka on the St. Johns River, then the major artery into Central Florida from the East Coast. Consequently, an army garrison was established upstream, on the southern side of Lake Monroe near a trading post. Called Camp Monroe, the log breastwork was attacked on February 8, 1837. It would be strengthened and renamed Fort Mellon in honor of Captain Charles Mellon, the sole American casualty.General Zachary Taylor had a road built connecting a string of defenses from Lake Monroe to Fort Brooke (now Tampa). The town of Mellonville was founded around Fort Mellon in 1842 by Daniel Stewart. In 1845, Florida became a U.S. state, and Mellonville became county seat of Orange County, formerly called Mosquito County with its county seat across the lake at Enterprise. Orange groves were planted, with the first fruit packing plant built in 1869. In 1870, "General" Henry Shelton Sanford bought to the west of Mellonville and laid out the community of Sanford. Believing it would become a transportation hub, he called it "The Gateway City to South Florida."
