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 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.
