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.
Micanopy
Following the American purchase of Florida from Spain in 1819 through the Adams–Onís Treaty, and the subsequent appointment of Andrew Jackson as territorial governor in 1821, large numbers of American settlers began colonizing northern Florida during the next decade. Micanopy opposed further American settlement of the region. As conflicts arose more frequently between the Seminole and settlers, the Seminole were driven away from the Florida coast and into the extensive wetlands of the interior. By the Treaty of Moultrie Creek in 1823, the Americans seized 24 million acres of Seminole land in northern Florida. The Seminole moved to central and southern territory.
