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.
History of Bartow, Florida
Meanwhile, European powers were struggling to establish themselves on the Florida peninsula. The Spanish, French and British all gained and lost control over Florida before the United States finally gained permanent control of the peninsula in 1819. By this time, the Seminoles had established themselves on the peninsula and proved to be an impediment to white settlement of Florida. At first, the United States attempted to force the Seminoles onto a large reservation covering much of Central Florida, which included the land now part of present-day Bartow. At the conclusion of the First Seminole War, the United States passed the Indian Removal Act of 1830, which attempted to remove most of the Seminoles to Oklahoma.
