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.

In 1763, France ceded Louisiana east of the Mississippi River to Great Britain in the Treaty of Paris. The area became part of the colony of British West Florida. In 1783, British West Florida was ceded to Spain as part of the Peace of Paris, and the area became part of the province of Spanish West Florida. The United States claimed West Florida in 1803 as part of the Louisiana Purchase. However, Spain disputed this claim. Tensions between the United States and Spain grew as many Americans began to move into the area. A large number of these immigrants were Tories who resented Spanish rule. On May 14, 1812, immediately prior to the start of the War of 1812 with Great Britain, with whom Spain was allied, the United States assigned the claimed area to the Mississippi Territory, even though the area was still governed by Spain. On February 12, 1813, the United States Congress passed a statute giving President James Madison authority to occupy the area. In April 1813, an American force occupied Mobile and received the surrender of the Spanish commander.
