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 Louisiana
As a result of his setbacks, Napoleon gave up his dreams of American empire and sold Louisiana (New France) to the United States. The U.S. divided the land into two territories: the Territory of Orleans, which became the state of Louisiana in 1812, and the District of Louisiana, which consisted of the vast lands not included in the Orleans Territory, extending west of the Mississippi River north to Canada. The Florida Parishes were annexed from the short-lived and strategically important Republic of West Florida, by proclamation of President James Madison in 1810.
