United States territorial acquisitions
West Florida was declared to be a U.S. possession in 1810 by President James Madison after the territory had declared its independence from Spain. Madison ordered the U.S. Army to take control. Six weeks later, the army entered and occupied the capital, St. Francisville, putting an end to the republic after 74 days of independence. Spain did not relinquish its claim to sovereignty (see West Florida Controversy) until ratification of the Adams–Onís Treaty. General Andrew Jackson personally accepted the delivery of West Florida from its Spanish governor on July 17, 1821.
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.
