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.
Cuban Americans
Before the Louisiana Purchase and the Adams–Onís Treaty of 1819, Spanish Florida, and when divided during British occupation, East Florida and West Florida, including what is now Florida and the Gulf Coast west to the Mississippi River were provinces of the Captaincy General of Cuba (Captain General being the Spanish title equivalent to the British colonial Governor). Consequently, Cuban immigration to the U.S. has a long history, beginning in the Spanish colonial period in 1565 when St. Augustine, Florida was established by Pedro Menéndez de Avilés, and hundreds of Spanish-Cuban soldiers and their families moved from Cuba to St. Augustine to establish a new life.
